So the SCORE is in for the KB Ear KB02! It's a musical, sweet sound, but I often wanted a tad more treble air and sub-bass boost. It got a respectable 77/100, so definitely an A-tier product for me. I find it's somewhat genre-picky. Sometimes it really sings, and sometimes it sounds a bit lackluster. I was REALLY enjoying it last night with some 80s music [Christopher Cross.] On the other end, I wouldn't pick the KB02 for EDM... [Owl City] because it's not crispy enough in the treble, and not quite punchy enough deep down low. I think the KB02 has a retro sound, and works better with older music, or smoother music [such as Billie Bossa Nova-style songs.] So the Kb02 is one I'll keep for variety, but it's not an all-rounder. [And of course, my raving first impressions were through the DC-Elite, and my tests here were NOT using it. I got to be consistent!]

I was also re-evaluating the Tiandirenhe TD02 and Tangzu ZeTianWu... My initial scores had the TD20 ranked higher than the ZTW, and I wasn't sure that was actually representing my feelings. I wrote about this more in the Musicopia thread, but the revised scores are: TD20: 88/100. ZTW: 91/100! I like these both a lot, but the ZTW has more treble air, which fits my preferences better. However, the TD20 I think has even better bass and better stage!

Apparently Fiio going to release Fiio BTR-19 late this year (approx november) for $275 ish
with special edition that will either have Tube-amp or R2R DAC.
apparently its made to fill the gap that discontinued Q-Amp series made.
---
I saw these as well, the Cayin is very very interesting with that form factor. I'll be on the lookout for the BTR19 and this RU9 they're talking about. I wonder If the Ru9 will act as a battery bank of some kind... I doubt it but it just makes me think considering I have a battery bank that looks so similar to this.

Got some new eartips!

Dunu S&S, these are really good! I was skeptical about them because of their shape, but I have to admit, these tips are very comfortable. I usually use M size, but I ordered the L size because of the mm sized table. At first I thought that I was wrong, but no. They just look big, but they are fit very well. I really like them! I prefer them over the CP100+ for now.

Now to the ST35, as I understood they are similar to the cp100+. Haven’t tried them yet, but, I got them for 3.4$? And it comes with a storage box. For me it is a pure value, it is cheaper than a single cp100+ that doesn’t even come inside a box.

Have been busy lately… more reviews to come very soon!

Before I was dropping snazzy jazzy ditties here, in the music threads, and Musicopia, I was (am) an old thrash head. Metal is my passion, but thrash metal in particular, is my home team. So much so, even @Jmop dropped a thrash album or two my way, and those rec's were fantastic. But starting in late 2023 or early 2024, I got hooked on jazz in all it's forms, and it has taken up the majority of my ear time, but I still listen to plenty of thrash metal, both old school and new breed. First listened to thrash in 1984, when a buddy of mine brought Kill 'em All to gym class. Then a year later, another buddy let me listen to a tape that had Metallica's Kill 'em All on one side, and Ride the Lightning on the other. It got me kicked out of driver's ed class. I didn't care. I was mesmerized and hooked. Then I got a tape with Exodus - Bonded by Blood, Slayer - Show No Mercy, and Mercyful Fate - Don't Break the Oath (not thrash). There was no turning back. Then a couple years later, I moved to ground zero. The Bay Area. Home of the Bay area thrash metal movement. My thrash collection is about 300+, about 40 years later. My early albums paved the way, and were with me through some pivotal moments in my youth. Typically, when I'm listening to my thrash playlists or albums, it's either with the CCA Trio, ISN H60, 7Hz FIVE, Tangzu Wu Zetian, and more recently, the stunning goodness of the KBear KB02. @Redcarmoose @Zerstorer_GOhren probably know all these albums? Check 'em out if you get the chance?

Wow. This collage is a throwback to my bedroom walls at 12 years old! Back when CDs came in cardboard boxes, I did what most other pre-teens did with those boxes: I plastered them all over my walls. Only big hitters for me that are missing from this group are maybe Laaz Rockit, Anthrax, Sepultura, and Coroner. The height of the era for me was catching the 1990 Judas Priest arena tour with Megadeth and Testament. I'd never now be caught dead going to an arena show (and only occasionally still listen to metal), but at fourteen, it was a genuinely religious experience. I'd soon thereafter move into punk, folk, psychedelia, and classical music for most of high school, but thrash and death metal were my first real musical love.

Class D doesn't necessitate more distortion than class A and can have less distortion than class A while using less feedback even at low power output and it can have an output impedance in the <0.1 ohm range. Also being able to power headphones well with a single portable device is neat.
Yeah, the only real downside to Class D is the switching noise. Used to be hard to filter properly out of hearing range. But that's been solved by the big players, so it's a non-issue (for full-size speakers amps, at least). AFAIK distortion was never an issue with Class D. It's always been impressively linear, even in its early days.

Kinera has beautiful IEMs
In my opinion, right now in the Chinese IEM market, Kinera’s effort on their IEM designs is just on another level.

If there was an IEM beauty contest, I’m pretty sure a lot of their IEMs would win first prize! Their attention to detail, creativity, and craftsmanship really stands out.

Oh nice, im waiting for some feedback about this new Xduoo DAP....make awhile they haven't launched one and they were among greatest budget DAP maker before, still use weekly Xduoo X3 and this Xdoo X20 and main reason is because of LINE OUT...

is there a dedicated line out with X5 too?

LOL

I know the Estrella was a polarizing set, to say the least, but the faceplate and shell design is beautiful in my opinion. Not shocked that Yanyin did a little copying.

Paul likes the Letshuoer S12 (2024) more than the Aether! :astonished: 🤷‍♂️ Said it has more upper mids and lower treble presence than the Aether, and as anyone who owns the S12 (2024) knows, it's a bit "thicc'er" in that region than other planars, and the treble, while present, is a bit more controlled and less airy/shimmery/planar timbre controlled than many other planar sets. If the Aether is less?! This is starting to sound like a bassy, safe treble set ("meta"). Hmmm....This might explain HBB being so enamored with this set?

Yup, 24 bits is slightly higher resolution than the tolerance of the capacitors that need to be in all of our gear can reveal. Apparently, we could be setting our ADC's to 32 bit recording, if we choose to preserve performances' loudness levels better than we can distinguish them on our gear at this time. If you want to be able to distinguish loudness levels better, it leads to cranking up the 24 bit recordings, so that you can hear the sweet sounds of stuff that gets to be quieter than the basic 16 bit version would let that transient get away with, for being in there, since with 24 bit, the ADC can round the volume downwards, there are 50% more volume levels below 100% loudness for 24 bits to play with.
After this new 24 bit capability that even $200 copies of albums on big pro reels of tape could be jealous of dies down, as the new normal, however, we will still be stuck with digital's problem in the first place, the samples that digital recording requires completely ruin it's chances of revealing details in audio. Please upgrade your recordings to at least the 192khz everyone's old and cheap gear and phones can be doing, at this point, recording engineers.
Nice name, ExTubeGamer. My tube amp just stopped turning on properly last week, and I decided to try out this little old mini-system from 1979 made by Technics. It's a matching half-sized set of pre- and final power- amps. Except it turns out that it's actually the little half sized 40 watt mini system for people who already have the $$$+ systems in their listening rooms, and next they also want a little something in the kitchen or the office, as each half if this pair sold for $1k in 1979. Anyways, now that I've found out the original MSRP of the pair, they no longer completely blow me away for that price, except now what I thought tubes won about, it not so true. My sound is not a little grey men version, and my new box that rebuilds a digital signal and outputs a super I2S signal to my gear is making my soundstage gigantic in all dimensions besides width, sounds more open, and adds slam to the bass from my DAC. I know that my tube amp will probably show that too, but this one has all this bass besides how low it can go going on. Since Sia is singing a song right now, I still have to admit that as much as I want to believe, it's true that a tube is more accurately the size of her voice box in my playback, and she may not sound as alive, due to being a solid state cover version of this recording. Oh, Styx came on next, I must be having a vocalist's day. Yeah, he's not as realistic as with tubes, either, but he's still super-neat and tidy sounding, and shouldn't complain about being solid state compared to the female vocalists. Even though that may be a mean and biased POV, but come on, Styx is so a neat and tidy band, compared to most guys. It's definitely a tougher choice comparing a $1500 tube amp to a $2k SS amp, than my original $1500 tube amp VS my old $800 solid state amp comparison. Plus, this is an amp that sounds like a 1979 version of the best that 1978 had to offer, except for the part where NAD set a new record for becoming famous off of it's new $500 amp that wins to the audiophiles of the worldwide community. Probably, NAD defeated the part where all other amps were stuck with sounding like <1978.
Anyhow, since you're the smart guy here, you should get picky about not listening to your tracks the simplest and least noisy way possible, and test to see if your low powered SSD can give you a more confident read than you ever got from optical discs, as well as free you of mechanical HD noise. Next after that, you can try for the ultimate test VS the original CD spec: uncompress your files, and get a silent and confident read of uncompressed WAV files from your audio ssd, which could be a 2tb square external drive only 2x as wide as a thumb drive, but using a USB 3.2 C cable, for 900mb+ data transfer/track buffering speed. Swapping to uncompressed WAV files instead of FLAC compression, (I only EVER used FLAC instead of lossy mp3's, except for when my little portable audio player before my phone came out had it's own onboard 128GB or something), all of a sudden nothing is processor noise-injected versions! All of my favorite tracks read silently from my SSD are noise-free, and now I know exactly why I like headbanger type of stuff, instead of just Beethoven and Vivaldi all the time. Compared to the FLAC versions, every sound in music is designed to make you drift off to sleep during it's playback. If you want an alarm clock sound for your phone, get it to play a FLAC version of a lullaby. It will do the opposite of make you sleepy, since all of it's sounds will be processor noise-injected, and have an impersonal glare to it, keeping you from thinking it's reality.
Storage is getting cheaper faster than the audio industry is keeping up with. A 2TB external SSD that can read/write at 900mb/s is only <$200. Once you've uncompressed enough onto it to almost fill it, after you wake up, you will easily be able to buy a 2nd one, even the 4TB version that will no longer be 2x as much as your $180 or whatever you paid for the 2TB low-powered silent (and faster?!) drive. Oh right, I could probably buy a 8TB mechanical HD for that price. But I hear the noise of those going into my output buffer! Ok, I still keep the original rips on a mechanical in FLAC. But my external SSD will probably last longer, as well as winning silent reads and speed of buffering awards. Also, as a gamer, an external SSD at 800mb/s is not wasting your precious NvME drives' new uber 3Gb/s game loading speeds on music buffering. As nice as it is that the HD makers discovered that maxing out an interface's speed with an improved SSD drive controller is not so hard to do, the problem remains that the max-throughput measurement is not as big of a deal to program load-times as the initial move to SSD access speeds, and if you want that spec improved, you need to spend the extra 25% for the better model the HD people keep working on trying to improve for you. You'll still be in the SSD era of load times, but you'll be more state-of-the-art, for your extra 25% $ that may help your load times better than the max transfer rate of your interface. That part is good for copying lots of stuff over, though, except you'll probably always just be moving stuff onto it from your oldest and slowest drive, and be stuck at that speed.
Seriously, ExTubeGamer. If that's your avatar, you should try hearing less noise injected into uncompressed playback from a SSD (I just picked external, thinking it meant lower powered, like digital likes until it passes through the DAC chip, after that, it's all about the same competition your $400 tuner had VS your $400 CD player, after your initial problem with locking onto a station that's not your loudest and therefore your city's reference radio station, what makes you think CD beats radio? What if I got a $1k tuner, to compare your local reference radio station pumping $ into the listener's end, to CD's from an only $400 player, compared to that station's pro-gear transmission?
Anyone who even remotely may consider radio, should your internet ever go down, should look into getting a radio tuner with a $400+ original MSRP for <$100. I had previously only ever heard radio on my receiver's built in crap tuner, or on the built-in crap tuners of car stereos. I had no idea that whatever you spend on a real tuner, is what radio technology can actually be doing, compared to everything else. Nobody escapes analog sections being the winners, after whichever format you choose. After that, the Nakamichi Dragon cassette deck was only $3500, and did not even send it's left and right channels to their own sides of the box, with gigantic 50w class A power supplies feeding each channels analog build, for some balanced loving of all your tracks. I was always stuck with admitting that I can't hear my $400 tape deck getting beaten by my $500 TT or $400 CD player, but oh yeah, I have to admit that I had to spend max money on blank tapes that beat the TDK SA-90's, otherwise tape would lose a bit of live-sounding. I didn't even have any good cables back in the 80's, lol. Oh shoot, I don't even think it was until post-2010 that I found out that plugging any gear, especially a power amp, into a $20 power bar, will totally stunt and ruin what that thing in a $20 power bar could actually be doing. Actually, maybe your desktop in a $20 powerbar stunts your digital outputs the most, for both audio and video depth and details, at that point.
Uncompressed playback returns us to the original audio fan's dilemma: too much good music at home will make you want to take a nap! So, compress it even more, and make it sound like your alarm clock is injected into everything. Eventually, your dog will want to kill your favorite artists for sounding like that all the time, too.

HiBy updated details for the R3 PRO II





Quick recap of R3Pro II
Selling price:$199*

The orange\green versions feature Ultrasuede back panels, while the black and silver versions come with frosted glass back panels, allowing you to choose according to your preference.#hibymusic
To be honest with you, this does not appear at all to be a aesthetic upgrade to the Hiby R3 II. As a matter of fact, it looks to be a major step backwards, and looks more like the R1, which wasn't the most attractive or sturdy feeling DAP. Now the innards might be a step forward, but the aesthetics are a definite step back. Not sure of my interest in this as a replacement for my R3 II?


@Okcerg - Yeah, I'm thinking the same as you. I'm probably going to hold out and wait until it's on sale with Summer sales or even LEC sales? Subject to change at any moment, but certainly strongly leaning that way, as you are. I don't need another "bassy" planar set just for the sake of having another bassy set with controlled treble region, as both the S08 and S12 (2024) already provide that.
