Hifiman HM-801 RMAA Tests - Page 2  

post #16 of 795
Thread Starter 

Here's more results, from Line-Out, USB, S/PDIF: http://rmaa.elektrokrishna.com/Comparisons/Hifiman%20Line-Out%2C%20USB%2C%20SPDIF.htm

Same thing, it's just not a very good amp/DAC. I also tried the amp board from the second Hifiman, same results. Verified twice.

 

Sonic748i,  I'm sorry, I know how proud you are of your Hifiman>RSA>JH13 rig. But yeah, maybe spend the $30 on a Clip+ and give it a listen. You might find that you really don't need to carry that brick around with you, and you get an actually working firmware (with gapless playback) as well.

I have both the Sansa Clip+ and the HM-801 (along with a modded iRiver iHP-120 and Pico DAC).  And the HM-801 is easily better sounding to me than them. 

 

What sound card, drivers, and OS are you using for these RMAA test, dfkt?

Keep in mind that the USB DAC implementation is not very good.  It goes through SPDIF rather than straight to I2S.  I was never a fan of the SPDIF input, would much rather have a proper USB only implementation as I have very little use for coax SPDIF in a portable.

Hard to believe I got two faulty Hifiman players, both sounding and measuring a bit worse than the next average player by accident... Not to mention the missing high frequencies are rather clearly audible with decent phones - the Hifiman lacks treble and sounds more veiled than the next average player. Last time I checked they did sound the same in a volume-matched AB-test to my ears, but now my ears seem to be less clogged, and I hear a difference.

 

I'm using an Echo AudioFire4 for these tests, it's an accurate sound interface. I've been doing these tests for years, and I never heard of anyone finding any flaws with them, be it people from Hydrogenaudio, Rockbox, or others. You can have a look around: http://rmaa.elektrokrishna.com/

HM-801 lacking treble and sounding veiled?  Funny.  Doesn't sound that way with me.  Shall we post part hearing test results for proof too?  (Show me yours, I'll show you mine. ) The JH13's and Shure SRH840 are seeing the most time used with the HM-801 here.

 

But then again, I spend my time listening to and enjoying music, not artificially measuring them.

 

Perhaps I should fire up my old RME HDSP 9632 rig...

So it's "extremely hard" to click on the little "Insert Image" button at the top of the post formatting menu bar?

 

Granted, the new forum is no longer allowing PHP codes for posting images.  It's an extra step and annoying for sure.  Extremely hard?   Hardly.

Well, the treble roll-off is definitely a flaw in my book. But keep in mind that it resembles Wadia's Spline filter which has this roll-off for a reason (namely for improved pulse response), so it can absolutely imply a sonic benefit, apart from the lack of upper treble. Although I don't sympathize with this approach as much as I did a few years ago, I still acknowledge a possible specific sonic advantage compared to the classic filter implementation. Wadia players do sound excellent despite (or due to) this measuring flaw, so let's not condemn the HM-801 just because of this feature!

 

As good as the Clip+ sounds to my ears for its intended (portable) use, it's far from approaching the sound quality of my home rig. So there's definitely room for better sound even from portable players. And maybe the HifiMan is one of them nonetheless (I haven't heard one yet).

The s-flo is yet another nonsense product with horrible firmware and usability, with some advertising claims about "better" sound quality that's simply can't be true. People, don't be gullible fools.



Have you ever try Imod or diymod?

The Sflo is not the same, only on the HPO it is, the LO is flat all the way across.  Shig said he would keep and use the SFlo2 over the others if it didn't have a big screen and was smaller.  I think you should read more reviews and look at the hardware specs on the Sflo2 if that is the conclusion you came to.

 

BTW, the Clip+ doesn't sound as good as my 5 year old 2G iPod nano driving my dynamic IEM's go figure, might be a power issue.  A graph is a graph, take it for what its worth.

Every person who has bought the HiFiMAN immediately heard the sudden increase in sound quality including our very own jude over at Head-Fi who said the HiFiMAN sounds like anything but a portable audio player. It sounds like something that belongs in a full size rack plugged into a wall. They're reviews of the HiFiMAN compared to other MP3 players in which the HiFiMAN downright triumphs them. But anyways, lol, this article doesn't convince me one bit because what I'm hearing right now no other MP3 player can come close to mimicking. sad


Unless I got a faulty unit, or I am deaf. When I first get them, using the GAME module, I certainly didn't have any wow factor. What I think HiFiMAN is better than iPhone 3G:

  • HiFiMAN has a strong output, and music has more dynamic, or power.
  • To my ears, HiFiMAN in fact has very good instrument separation and imaging. Good 3D presentation.

 

I am using GAME module, which is designed to use with IEMs as far as I am concerned. However, it turns out that HiFiMAN has very bad synergy with SM3, which is my current favourite. I am assuming the 'Normal' EQ setting means flat (EQ off), and SM3 straight out from HiFiMAN headphone jack gives me the most forward mids I have ever heard. Just mids, and mids intruding into bass as well as treble. Actually I have to admit that my last post was a litlle bit exaggerated, but I am very disappointed with HiFiMAN, at least when pair with my SM3.

 

I tried to pair SM3 and HiFiMAN as DAC, but not much changes compared when I use them as player.

HiFi is not equal to a straight plot.

Synergy is a big deal.  I think too many people chase their ideal flat DAP, flat amp, flat phone and expect nirvana.  It seems like chasing a mythical white unicorn and even if you catch it you won't necessarily like the ride.

post #29 of 795

That's exactly what I was after, a flat DAP ( HiFiMAN ), a flat AMP ( RSA The Protector ) and a flat earphone ( JH13 Pro ). I'm experiencing audio nirvana everyday. indecision
