Amps that can drive the HiFiMan HE-6 planar headphones - Page 181

Hmmm... sounds like musicman59 is on the move. Wish I were in town:normal_smile :.

I am listening to He-6 driven by Teac AH01 speaker amp connected to preamp of Burson Conductor from source of BDP105.

The sound quality is almost equal to He-6 driven by Marantz PM6005 speaker taps connected with the same chain of machines.

 

Those pairings are well above the Emotiva mini-x A-100 with respect to SQ, so that I decided to sell it.

 

The high is well extended beyond the reach of my beloved He-5le, the bass is well controlled beyond the reach of HE-5le.

Previously my usual listening phone was LCD2.2 driven by Conductor.

Now my 90 percent listening is now HE-6 + Teac AH01, which is not properly esteemed here in Head-fier even though it has been well known audio company's product since almost 30 years ago.

My research of the best economical solution for HE-6 seems to begin to pay off.

 

What I read here is usually about very expensive speaker amplifiers which are usually beyond reach like usual person like me.

My understanding of D-class amplifier can be as smooth as Class A when they pass through proper low pass filter ( phone itself being LPF actually). And the usual specification of amps are not very helping.

THD and S/N ratio are not reliable indicators of performance, for example even though S/N above 85 db still generates hearable noise. Also  very low THD value actually did not guarantee the SQ.

 

I replaced the stock cable of Conductor with noise protecting cable, so that it could not be acting as dipole antenna that invites common mode signals.

And actually after this change the granular nature of sound is much more improved.

Perhaps, the high frequency was aliased back to signal band of headphone, but now it is prevented. I also installed power conditioner as well for this regard.

The consequence is significant.

I'm quite sure he has something cooking...:popcorn:    Every time he comes over to my place, my wallet cringes and my wife gives me nasty looks.:wink_face:

I haven't heard the Bricasti M1 (bit of a long shot there.)  I use AudioGD's ACSS connection from their NFB7.32 DAC - this input/output seems to have much less gain than the other outputs/inputs.  Using the XLR connection there was no clipping issues so I suspect there is enough power.  I would say there was maybe even 20-30% more gain with the XLR.  

 

I found that I needed to use 50/100 for classical recordings, and 20/100 for modern loudness wars recordings, which strangely were where I encountered the clipping - specifically on Has Zimmer's Hannibal OST on the track "To Every Captive Soul" where there is a very challenging section that has been compressed to hell.  I find the NFB7.32/M6 combination can handle this section fine when driving my HD800.

I just had a look at the specs of your DAC. The ACSS output is only 2 volts and the XLR output is 5. I'm using the XLR output from my Bricasti that is set at the factory default of 3.8 volts. Your XLR output is 2.5 times greater than your ACSS output. I have no issues driving the HE6 with my M9 and I'm using the low gain setting on my M9. Typical volume setting ranges from 60-70 out of 100. The volume control on my M9 is called a super expotential volume control that may be different from your M6. Nigeljames has a similiar set up to yours driving the HE6 and he has reported excellent results.

I haven't listened to the GSX mkII, but my friend said he tried his HE6 on it at RMAF. He told me that it sounded lean and lacked the power to drive the HE6 well. This account correlates well with what others have said about GSX mkII and HE6.

 

 

Not all that have "owned" this combo feel this way.  Lean? - heck no..  Lacks power?  - maybe, but not by much.  I'm sure the M9 is a great headphone amp for the HE-6.  However, if purchasing from Audio-GD and only for the HE-6 I would go with the Master 3 no question..

I didn't buy the M9 to drive only the HE6. I wouldn't be buying the GSX mkII for my only amp if I had the HE6 as one of several headphones. That is exactly my situation and I'm very satisfied with the M9.

In his review of the Master 9, Greed called the GSX mkII "thinner" sounding and he also had issues with its treble response. My friend, musicman59 whose ears I trust, told me that the GSX mkII and HE6 wasn't a good pairing in his opinion and that was enough for me. You obviously like the GSX mkII. Different strokes for different folks.

And you can't say if you like it or not at this point until you hear it for yourself - that's all I'm saying.    It's neither here nor there.  Like you said different strokes for different folks.

Teac AH01 has stayed with me more than 7 days, and showed its weaknesses.
It sounds thin and rolled off toward high region.
The thinness was not detected immediately but I realized it after listening several days.

The consequence led me to stay with more with LCD 2.2 + Conductor than He6 + teac ah01.
I decide to go back with Marantz PM 6005, which sounds fuller and more bassy with loudness button ON.
That combination led me to stay more time with HE6.

My quest to search the mass production of speaker amplifier with He6 due to the fact that usual THD of headphones has around 1%.
Therefore, 1 % plus THD ranging 0.01 to 0.1 % should be no difference.
Rather, being importance goes with other factors like Antenna effect of power cable, or inter connections, so that those picks up EMI noises which have then been aliased back to sound signal band.

however, this attempt was not very successful. When i chose low THD, the SQ generally better.
This is reason why partly usual people pursue after very low THD like audio gd master 9.

I am still think that being grainy is due to high frequency sound being modulated by similar range of frequency, which is likely aliased back of certain noise including EMI, or feedback oscillation of Amp.

Just wanted to post on this thread that I was able to acquire a super symmetry dynahi from another member here and that it doesn't have any problems driving my HE6's.  Only other amps I used with the HE6 were a mjolnir, EF-6 and yulong A18.  Compared to them the sound stage appears more expansive (EF-6 was more closed in).  Bass may be a tad more prominent (especially compared to the mjolnir).  Occasionally I used to feel that the EF-6 would accentuate a high treble "etch."  Haven't felt that with the dynahi so far.  I'm overall happy with the purchase.  One caveat,  I've never heard the HE6 on a good speaker amp.

That was a very good purchase.  Most likely the best headphone amp you can get for the HE-6s.

I saw that you were also waiting for a balanced dynahi to be built - would you mind posting your impressions of the amp vs your First Watt?  I'm just wondering if a speaker amp would make any difference for me.  I doubt if I will buy it though - have a set of HD800's that work well with the dynahi also.

Sure will.  It's said the Dynahi is one of / if not the best SS headphone amp to go with the HD800s..
