Onkyo A800 – "MASTER CLASS"

Nice headphone. Are these the ones that send radio frequency in addition to its sound? If so, that's really cool. Also, nice HP 1000
It was described as an audible radio wave, but I am not sure.
I used to be able to visit the website of this manufacturer and see a paper on the UST technology developed in collaboration with a university, but the site is now closed and the developer is dead.
I would be interested to hear this from anyone who comes to Japan who might be interested.

That is unfortunate to hear the developer is dead. That headphone seems to have a unique sound signature based on the article you linked in the previous post, "... I feel that it is the third drive system located between the dynamic type and the condenser type..." I will add the EXH-313 to my bucket list of Japanese headphones to try including more Sony old classics and the Kurada KD-P1. Also want to hear an Onkyo H900M one day as well. Got to figure out why they made a $10,000 version of it.

I know a few things about kurada about its predecessor kd-or12 but personally I doubt it's worth it.
SE-Master1 and some old sony speakers you might also like.
I am also interested in H900M but have never heard of it.

Nice, is that the Ergo Amt on the left? I am not familiar with the right, but that looks interesting as well. I’ve been interested in really open and unique design in headphones lately. That was why in the Kurada KD-P1 design because it was similar to what Sony did with the F-1 and MA-900. Have you tried the Mysphere headphone yet? It’s the successor of the K1000. So the Mysphere headphone have an amazing midrange (probably one of the best I heard) and the open design like the K1000 give an amazing imaging and soundstage.

Speaking on Japanese goodies. It's interesting that there are a lot of wood 🪵 type of headphones they like to make.

Denon D5000
Denon D7000
Denon D9200
JVC HP-DX1000
JVC HP-DX2000
JVC Victor Woodies HA-WM90
Fostex TH900
All Audio Technica woodies, including W2022
Sony R10, the obvious one.
Kurada and onkyo also have wood headphones. The onkyo SN-1 for onkyo.

Konohazuk H3 Headphones 😀

Only $100,000? pshhhh easy money.

Never heard of the Konohazuk H3 Headphones, but they look really neat. Plus it's affordable, so that would be a cool headphone to try one day when I got 200 bones lying around. I am also really digging the new Japanese woodies that have been release recently. The Onkyo SN-1 and even the new Audio Technica W2022B/W2022 have really comfy looking headband to me. Those Japanese woodies headphones look nice and comfy. The HA-WM90 just looks cool with its 100+ year old wood, might be comfy.

I have one. It is different to A800 and I don't think it soulds like ultrasone.

SN-1.jpg
Did you try the Pioneer SE Monitor 5? I'm curious how they compare since they seem to derive from the same design and seem to have several elements in common (driver, metal mount with double chamber, yokes) but cups and ear pads are enough to change the sound signature.

Protoss you genius! I recently bought the DowiTech pads because Protoss never misses on a recommendation. $13 bucks, why not. They were a little struggle putting them onto the Onkyo A800. The harder you work, the more satisfying the reward will be. When I finally got the DowiTech pads on and started listening to the Onkyo A800, first word that came out of my mouth, "woah". Oh my 😳... I was not expecting to hear this. As Protoss stated, 50% or pretty much 80% in my exaggerated language, the Subbass has been subdued and tamed! I wouldn't exactly say bass as a whole, mostly just the subbass category which is the rumbling and physical part of the music have been tamed. When the subbass has been tamed and is now on good behavior making physical contact delicately instead of punching your guts with its visceral kicks, midrange is veeeeeeeeeeeery sweet. I mean, this is the sweet spot of midrange. It hits all the good spots and man it feels good! The song I was first testing it out with was "Windy Spring" by WoongSan and I wanted to test vocals. Of course, the vocals melt in my ears, but man the piano sounded extra good. I think the reason why midrange was in the sweet spot is probably because subbass wasn't there overpowering the midrange. The music was able to focus more on the piano and my brain was able to 100% focus on the piano to appreciate its sweet melody. I still could hear the bass guitar, accoustic guitar, and of course WoongSan lovely voice. As Protoss said, only the subbass was tone down, but the Onkyo A800 still have the rest of the range and it is freaking magical. The only downside is that it loses excitement which is one of my favorite features on the Onkyo A800. The Onkyo A800 is easily one of the most exciting headphones no matter what the price range if you use leather pads. And excitement is what I am looking for on some genres like Pop and Rock.


Back in December 2022, I said I prefer the Caldera thin pads on the Onkyo A800 because the electric guitar, bass guitar, and drums sounded better to me. I standby it 50% now because of the DowiTech pads. The Caldera thin pads are still for someone like me where it can shine the Onkyo A800 exciting trait like its subbass, especially for my pop and rock songs. 1 example is one of my flavor song of the season, "無窮プラトニック" (Mukyu Platonic) by Valis. For some songs, I just want bass to beat me near death making my body feel the music rather than just listening to it. I think it gives a more "Movie Theater" presentation in music rather than a concert hall feel. Where I want to experience the music rather than just listening to it, does that make sense? If I want a more analytical approach and experience and appreciate all that midrange goodness, I will go with the DowiTech pads. If I want something with more excitement and go to the movie theaters, I use the Caldera Thin Pads. Thank goodness I have 2 Onkyo A800, now I can have both without all that swapping pads hassle :)

How are you guys fitting the Cowipads? I see no lip to attach them to. Do you stretch them over the original pads?

@Mommerman you can try the below method.

G'day fellow A800 owners! For anyone considering replacing / changing pads, here's my 2 cents.

1674037375048.png
Above is the stock twist on/off mounting plate. On the inside, there is a plastic ring that clips in on the inside perimeter. Make some markings to help you later from re-installing the ring. Use something to poke into the holes and flick up gently; careful not to snap the plastic (shouldn't matter TOO much). Once the ring is off, put the pad on the mounting plate and insert the ring back in. Done!

IMG_20220331_230921.jpg

Above pads are pretty much stock sound. Beyer-ish furry velour? 105mm fits perfect. go 110mm if you want a slightly larger ear space.

IMG_20220331_231132.jpg

Above pads ... Theeeese! Perforated-Hifiman-style-mesh-fabric-hybrid! 105mm. This is where the money is for me. This is how it's staying. Pads are wrapped around the gold ring.

A refined stock sound - more perceived clarity, less in your face overall sound, vocals stay the same as far as I can tell and slightly less bass. That foam (got it from from Hifiman packaging) brings the bass back up to stock pad level.

Imagine stock pads sound is 10/10 for intensity/aggressiveness/forward etc; these take it down to 8/10 which gives you a very noticeable refined version of that sound and keeps all the detail.

Same volume stock is a bit much for me, gets grating. Same volume with the perforated is like a breath of fresh air, all the information without the wincing. I can keep cranking up the volume with these pads (within reason) and it never bothers me!

Onkyo A800 has killer bass. Out of 100 headphones I tired only the Onkyo A800 made me say, "this is just crazy top tier bass," so here we are reducing the bass LOL 😆 😎

I just tried the Byerdymanic earpads. The real version
https://www.amazon.com/beyerdynamic-Velour-Silver-Grey-Other-Models/dp/B0016MMYKA/ref=sr_1_3?crid=9M68A6FYVJC8&keywords=beyerdynamic+earpads&qid=1691242509&sprefix=byerdymanic+earpads,aps,118&sr=8-3&th=1

It's very good. Extremely hard to put on the rings. The only way to get the rings is to rip off the og pads and use those rings. No other way sadly. Luckily I have spare parts. <- The rings, if remove improperly it can break and the earpads can rip.

Overall, very comfortable and bigger room space. And sound is very good. The Byerdymanic earpads are better than the og it's seem atm.

20230805_093135.jpg



Just order another Byerdymanic earpads 2x 😀
The sound is pretty good with them. Bass is tamed and controlled.
More sparkle and enegry.

You can bend the headband any way you want for the perfect fit btw.

いいですね、左側はエルゴアムトでしょうか?右はよくわかりませんが、それも面白そうです。最近、ヘッドフォンのオープンでユニークなデザインに興味があります。それが、ソニーが F-1 や MA-900 で行ったことと似ていたため、Kurada KD-P1 のデザインに採用されたのです。Mysphere ヘッドフォンはもう試しましたか? K1000の後継機種です。そのため、Mysphere ヘッドフォンは驚くべき中音域 (おそらく私が聞いた中で最高のものの 1 つ) を備えており、K1000 のようなオープンなデザインにより、素晴らしいイメージングとサウンドステージが得られますERGO AMT and RP-HDA100.

ERGO AMT and RP-HDA100.
The ERGO AMT sounds quite good and irreplaceable when used with AMP2.
I have never used Mysphere, but I would like to try it because it seems to sound very good.

The A800 pads were put in the groove without using rings. I am currently enjoying the original pads.

This thread is a bad influence.
Makes me want to purchase one and give it a shot.

@stasta Nice, that is good to hear. I definitely have to put the ERGO AMT on my bucket list to listen to. I also got to try the Onkyo A800 with the original pads one day. I noticed one thing with the Onkyo A800 is that it has really good stock materials like pads and cable. The stock cable is absolutely amazing and is probably one of the best stock cables I ever used. You and Protoss enjoy the original pads, so I know I have to listen to that as well one day.

Regarding the Mysphere headphone, easily the best midrange headphone I ever heard in the market and maybe of all time. I was fortunate to listen to a lot of headphones in the summit fi range, but at the end of the day, they still feel like headphones to me and nothing game-changing. That is why I was pretty burnt out in the hobby last month and just wanted to focus on my next speaker pick-up. I thought I would pick up 1 last headphone from this hobby and just focus on something else, which was both the Raal SR1a and Mysphere 3.2. The SR1a is probably one of the most high-level clarity and detail headphones I ever listen to. I think the only thing that could probably surpass it is probably Susvara on a good audio chain and some electrostats headphones like the X9000, Shang Sr., and HE-1. Even though I am using a entry-level speaker amp for it like the Vidar 2, it is powered by my Supratek 45 tube preamp and my really good R2R DAC. On a better speaker amp, I will probably get a better bass response and the soundstage will probably expand more. The resolution in the bass is also amazing. Probably the best-sounding bass compared to even the D8000 Pro LE and Caldera. The quality of the bass is really nice, probably have to compare it to the ATH-L3000 one day when I feel like it. The only thing I am disappointed in terms of its bass is that because the headphone is so quick, the bass decays too quickly and doesn't have that nice "oomph" to it. The Mysphere has a better bass punch while the Raal has a better bass texture, kinda like how I compare my Onkyo A800 vs. ATH-L3000 where the Onkyo A800 has a more satisfying bass while the ATH-L3000 has a more "audiophile bass". The reason I am bringing the Raal Sr1a up is that even though it has a high amount of clarity, something about that headphone still reminds me that I am listening to something digital and not real. (This little impression is to build up the Mysphere 3.2).

Now, Mysphere 3.2, that is a different story. Here is a mini-impression I did in another forum below. TLDR is that the Mysphere 3.2 is the most realistic-sounding headphone I ever heard in the midrange. The Mysphere midrange is unmatched, except for maybe the Susvara from people's opinions I trust, but the Mysphere does have the most realistic presentation for many of the acoustic instruments (particularly string, percussion instruments, and vocals). Synthesized music, nothing to write home about. The Mysphere truly shines with acoustic music. The Mysphere 3.2 is the pickiest headphone on the source (music files, CDs, Vinyl), amp synergy (I never have an issue with it so far with 3 different amps, but I heard from other people that the bass gets uncontrolled and you lose its magical midrange on the wrong amp synergy), and probably the most annoying headphone to wear because positioning on the frames is everything on that headphone. But once you deal with that hassle and everything is in a "perfect world setting", it is the most rewarding headphone I ever listen to.

Mini-Impression below:
"Now let's talk about sound. 1st impression, these headphones were magical in the mids and the vocals sounded amazing.

The bass sounded weird to me and there is some clipping, but only in certain tracks and volumes. It's honestly more picky with modern pop music vs. pop music from the 80s. I could still listen to modern pop music, just have to set the volume median - low, again very specific on which tracks I have to do this to, mainly tracks with extreme synthesized bass. I feel like I can listen to Daryl Hall & John Oates and Michael Jackson tracks in high volume without the bass sounding weird or distorted. Coming from a person that really enjoys the Sennheiser HD600 and HD580 Jubilee, the bass sounds good and the mid-bass is punchy. I think I got a jumpscare on my first listen with the Mysphere 3.2. I forgot which song I was listening to, but I did a test song with classical and switched to pop. Then on the same level with no expectation of bass, because a lot of people said this headphone had no bass, the mid-bass punches me almost out of my seat. It's not the hardest punch I felt, but the Mysphere hits pretty hard. I knew the Mysphere had bass, but I thought it was with only the Viva Tube amp. The Allnic HPA-5000XL was able to give the Mysphere a good bass response as well. I am used to headphones that make bass really stand out like the Onkyo A800. When listening to “Dove - Cymande”, compared to my usual Onkyo A800, the bass guitar was on the weaker side meaning that it doesn' t particularly stand out in the music. It was more in the background as the bassline should be. In the track “Isn't It Romantic - Bill Evans Trio Live” you can really hear the bass being plucked and really hearing the vibration in the air echo.

My favorite sound from the Mysphere 3.2 has to be many of the acoustic instruments and female vocals in modern recording. I agree with many people when they say the Mysphere really shines with organic music and live music. One thing I really like about the Mysphere 3.2 vs a lot of headphones I tried in the past (including my ownership of the Caldera and D8000 Pro LE which is in the similar Retail Price Range of $4-5K as the Mysphere 3.2) is that the Mysphere on my particular setup, have this magical way to remove equipments from the music. What I mean by this is that you can kind of tell the quality of a person’s mic with a good headphone. With the Mysphere, there is no equipment, it is just you and the artist. In a good recording, it really sounds to me like there is no barrier between me and the artist. Before, I had the mindset that there would always be a barrier and nothing would be close to real life. I used to think you would always hear the artist through a filter of their equipment. That is why I particularly don't like listening to classical orchestra or acoustic music unless it's live or through speakers (because I like the soundstage). With the Mysphere, it shatters my expectations of what I used to think about headphones and gives me the ultimate immersive experience that I thought wasn't possible. With the electric guitar and bass, that is a different story but that is also why I specifically said my favorite sound from the Mysphere is acoustic instruments and female vocals. There were some recordings where I thought, dang the piano sounds flat. But switched to another recording and the piano sounded great. That is why I also specified modern recordings because I feel like most modern recordings of acoustic performances are really good. There are some good old recordings, but you will have an easier time looking through the newer recordings to get this no-barrier experience. am also hesitant to say every acoustic instrument sounds realistic as it is heavily dependent on how well it's recorded. An example in one of the classical recordings, the church bells sounded light and didn't have enough weight in its sound to sound real to me Same with some piano recordings where I wish there was more weight in some of the notes, but there is some piano recordings where it sounds very satisfying.

Soundstage, with the Allnic HPA-5000XL, I agree with a lot of https://www.sonusapparatus.com/2022/01/mysphere-3-1-3-2-impressions/said in his Mysphere article where there is a little exaggeration of the distance between each performer and that the soundstage is holographic. I want to add there is a lot of depth in the soundstage as well. I am not sure if that is thanks to the Evo B4B 21 or the Supratek Preamp adding depth to this soundstage, but I will give credit to both honestly lol. I think both of these pieces of equipment vastly increased the depth of my soundstage and I could hear the sound echos with a great amount of height. To me, it feels like I am more immersive with the performers where I am in the center of the music and everything is being played around me. That was probably one of the most fun I had listening to music and the stage feels so vast and big to me. This is truly an alternative option to escape reality, don't know if this is the healthier choice lol.

Did a little A/B comparison with the Sennheiser HD580 Jubilee and the Mysphere 3.2. The Sennheiser HD580 is more forward in the vocals while the Mysphere is not recessed like the Sennheiser HD250 Linear 1, but vocals seem right in the middle where it is not exaggerated to the front but is where it should be. Mysphere 3.2 obviously blew everything else in the waters, it wasn't a competition lol. Resolution, bass, a more immersive experience where the Mysphere dispels barriers between me and the artist. still say the Sennheiser HD580 Jubilee is the GOAT cause Sennheiser has brought so many smiles in my memories I have to give them credit somehow. Didn't really A/B with the Raal SR1A because its not fair since I am using the Mysphere with the Allnic HPA-5000XL and the Raal with the Vidar 2. One thing I do like about Raal is that the music I like to listen to on the Raal is the opposite of what I would listen to on the Mysphere. I have a guilty music genre I really like to listen to and that is Vocoloid. The vocaloid genre kinda evolved to more than just the Vocaloid and more about the producers. Songs like “Odo - Ado”, “Hibikaze - Reol”, “DIAMANTE - IA (Sho Fujiwara)”, "Demon Lord - Kanaria" , and etc.

I think that is it for the 1-week impression. My chain is ROON Rock - Intel NUC 7i7 > EMM Labs NS1 > [AES] Mojo Audio Mystique EVO B4B 21 > Custom 45/6SN7 Tube Only Supratek Cabernet DHT > [RCA] Allnic HPA-5000XL > Mysphere 3.2 with Onkyo A800 ribbon cables.

TLDR:
Pro:

  • Very emotional headphones
  • Extremely good with the acoustic guitar
  • Sounds like the equipment disappeared and listening to the instrument/vocals raw
  • Immersive soundstage
  • Truly shines with acoustic music and huge orchestras.
  • Psychological rock music like “Voodoo Child (slight return) - Jimi Hendrix” and “2000 Light Years from Home - The Rolling Stone” is a trip with the Mysphere 3.2 and Allnic HPA-5000XL with my preamp/dac combo because of the good instrumental separation and soundstage maaaaan! Some rock songs are really good too like “Abraxas album - Santana”, especially with how they open the album up with “Singing Winds, Crying Beasts” which is really magical.
Con:

  • Synthesize bass sound distorted to me in a loud volume. Got to lower the volume on my setup.
  • Get some clipping/rattle when playing the big bass drums at a really loud volume ie classical music, but that is a lot of headphones tbh. It's just I'm used to that with my current bass-heavy headphones.
  • Very picky on how well the music is recorded/produced in order to sound amazing. Way more picky on the recording vs. any other headphones I have experience with."

The only headphone from people's opinions I trust that can match or potentially be better in the midrange is the Susvara. Different presentation though where the Mysphere is supposed to be closer in terms of real life while the Susvara is more analogue-like, meaning its more warm and richer in tone. At least is how I seen people describe the 2 headphones and I agree that the Mysphere is closer to real life. I will probably pick up a Susvara either in December or next year since I am planning on purchasing a classic gear in October already. I heard the Susvara can be driven by my Allnic HPA-5000XL amp pretty well, it's just they say it's a curve ball in that retail price range because of it's unique sound presentation and if it actually synergizes well with the headphone, it really makes that headphone take off all the way to the moon.

Now, back on topic to the Onkyo A800 since this is an Onkyo A800 thread. I think the Mysphere 3.2 headphone is a nice complement to the Onkyo A800. They both have the same headphone connector, so you can use the same headphone cable. One thing is that the Onkyo A800 is unmatched in terms of satisfaction in the bass region for me. I tried headphones like the Atrium Closed (Olive version) and the Abyss 1266 TC at CanJam recently. I will give the benefit of the doubt since Atrium Closed in different wood will give a slower decay which I will probably like more and the Abyss 1266 TC setup (3 different setups, DCA stack, Headamp new CFA3, and RSA new amp) is either not compatible with the Abyss since that headphone is hard to drive or the hotel power issue was giving problems to those setups and I couldn't hear the full potential of the Abyss "legendary" slam. At this point, I am pretty tired of buying more headphones and will just live with the Onkyo A800 and just wait till I get 2 subwoofers for my speakers for more slam. So Onkyo A800 for the satisfying bass-heavy music and the Mysphere 3.2 for the midrange on a more "realistic" presentation. If you own an Onkyo A800, I would recommend giving the Mysphere 3.2 as a good companion, second thought, let me take that back. I will only recommend it if you are willing to level your audio chain to a higher degree for both the Onkyo A800 and Mysphere 3.2. The reason, like I said earlier, the Mysphere truly shines in higher level gear and is really picky on what gear gets along with. But it is truly satisfying and worth it if you are able to achieve it. And if you can achieve that true midrange magic with the Mysphere, that same audio chain will most likely tame the Onkyo A800 bass and you get a nice balance of satisfying bass and good midrange. So bass focus music, Onkyo A800, more realistic midrange presentation, Mysphere 3.2.

*Edit: I have to re-edit some of my stuff lol. Is there a character limit in this forum? If it still looks funny, it is what it is.
