HifiMAN HE-6 Planar Magnetic Headphone - Page 722

post #10816 of 19444

I would say upper mid to lower treble region.

The sound is not brittle, it's just glary and offensive.

 

I could probably give many examples where that's the case: any classic rock song with drums would show it.

I just don't feel comfortable with any song, actually. I get that annoying feeling that something is not right, even though I cannot tell what nor why.

EF-6 and what DAC?  I don't have the same experience.  I'm mostly listening with the F1J / DP-777.  I can't duplicate it.  What track are you hearing this on?

SA-2, Ciunas or Chord QuteHD. Except for the Ciunas, they're probably all slightly south of neutral.

 

This is only when I use the Alpha Pads, actually. I have no complaints with the stock pleather. You might not experience it with your denon pads either.

OO  only with the Alpha Pads...  OK..

OK, so I've decided to see for myself if driving the HE-6 from a speaker amp REALLY makes a difference as compared to driving it from my V800/V200 combo which delivers 2700 mW/11.6 V into 50 ohms.  At the same time I've been wondering about tube amps so I'm thinking of killing two birds with one stone.  Problem is, I know nothing about speaker amps/headphones nor about tube amps but being a glutton for punishment:

 

I'm considering getting either the Almarro A205-A or the 318B model, they're designed and built in Japan and especially the 318 looks drop dead gorgeous imho.  The 205A puts out 5WPC into 8 Ohm, the 318B 18WPC.  See http://www.eugenehifi.com/Almarro/htm/Almarro_Amplifiers.htm for some info.

 

FWIW:  I've read reviews on this site where people describe excellent results driving the K1000 even from the 'only' 5WPC A205A and the amps get some rave reviews on sites such as 6 Moons (where reviews should sometimes be accompanied by a health warning imho but that's a different issue).

 

Any thoughts about these amps and the HE-6?   I'd like to use the amp to also drive my HE-500 and HD-800 cans, it would be fed from my V800 DAC.  Nervous as hell about blowing something up.  Is there (apart from watching that volume dial) something I need to keep in mind? And last but not least:  I suppose the only thing that needs to be done to connect my cans is to get a connector that plus in to the speaker out and terminates in either XLR or a standard 1/4 in female headphone connector, right?

 

Lots of probably stupid questions, I know, but as I said, I have no experience with this and am trying to gain some insight.

post #10821 of 19444

The preferred connector would be a banana/spades to 4-pin XLR connector.

Some amp don't like that you shortcut the L and R V- which is what a single ended headphone cable does. Go balanced to avoid this.

 

As for the amp, songmic is selling his Pathos: http://www.head-fi.org/t/694291/price-drop-pathos-classic-one-mkiii-gold-aero-7308-tubes

I don't have personal experience with those amps but just by spcs I don't think they will be enough for the HE-6. 5 watts @ 8 ohms will translate in 0.8 watt in 50 ohms and 18 watts @ 8 ohms are about 2.8 watts @ 50 ohms.

 

IMO I would not go with less than 30-40 watts @ 8 ohms minimum. Just my opinion.

Just an important note to add, if you're going to be using a speaker tube amp to drive the HE-6 an impedance box to match the amp speaker post impedance is essential in order to protect the transformer (e.g. Hifiman's own impedance box). Or you can do a simple hookup with resistors. I don't have an HE-6 but am driving an HE-500 off speakers posts of a tube amp (MP-301 MK2) fed from a tube buffer - it's my favorite and most musical set-up (at least to my ears). I think the 318B is worth exploring. Class A tube amps do not seem to require as much swing to sound good. I get a lot more out of the tube amp at 7 watts for 8 ohms than I do out of good solid state amps on speaker taps, eg, my Pioneer SA-9500II (80 watts) or Luxman R-1050 (55 watts). Experiment but just remember to add an impedance matching of some sort in the chain. Oh yeah - something else to keep in mind - resistors will chew up some of the power leaving even less for the headphone.

post #10824 of 19444

Exactly!

 

To reach appr. 8 Ohm, you need a 10 Ohm resistor in parallel on the speaker tabs. This means that the resistor gets 5/6 of the power while HE-6 only gets 1/6 of the output power. With a 18W amp HE-6 will receive 3W. That's about okay if you don't play loud, but nothing impressing - especially if you want to be able to play at loud levels.

 

My Leben CS300 is 12W in 8 Ohm, and I think with 2W for HE-6 it is a little on the low side, but adequate for normal listening levels (not loud). At 3W you will only have about 1.5 dB more max output ...

post #10825 of 19444

I've mentioned it in the amp thread, but I say ditch all these resistor shenanigans and use an autoformer to bring the HE-6 down to a proper load.

Well, what would the overall cost and performance benefits be over resistors?

post #10827 of 19444
It would cost at least 175 and I am not sure of the overall benifit of adding in the inductance . It would have an effect on the overall impedance. I think from a pure electrical point of view it works well and I thought about it. But you would still need a resister is cross the speaker output to achive a resiable resistive load for the amp. I asked what exactly happens and why it is needed , but I never did get and answer to that. It could be there is so many amp designs that there is no one answer for all.

Well, I'll give Armaegis a chance to chime in, but right now it's sounding like more of an expensive complexity than any possible sonic benefit over resistors. Not saying this may be true in this case, but I've seen many designs that are more of an intellectual exercise than what is practical and adequate for the job. I guess you could say I'm an advocate for the K.I.S.S. principle :tongue:

And I am in complete agreement to your reply brunk. Although this is a needed thread is a little to complex I think overall a couple of resisters is all we need in most applications .
However I have just purchased a speaker amp for the sole purpose of using it with headphones , so I have been reading and have bag
Full of ten watt resisters . Lol.
post #10830 of 19444
I wish to use the amp with the he6, lcd3 and hd800. If they all sound good.
