That said I did hear a little distortion in the lows and highs when I first got my HE6's. After about 80 hours on my HE6s I found the distortion was coming from my Realiser when I went below a gain of -15 but I have corrected that with the addition of my ADG19 DSPv5 and not loosing any AQ. Now I can use my Realiser at gain of 0 with NP, there by lowering the volume level of my Woo. I should add that the distortion was not there with music but only with movies.

 

Anyway I now only use my HE6's.



 I emailed Jack to tell him about my experinece with the WA5-LE and the HE-6 reagrding the difference in sound between the high impedance and low impedance outputs. Here is his reply:

"There is no problem at all using the hi-z output. I am having the same problem here. This is puzzling us as we cannot get the reason for it. I will have to talk to Fang at Head-Direct to see what makes this phone different.

Jack"

 

At least I can  run the HE-6 out of the high impedance output safely where they sound magnificent.

 

Thanks for the update.

 

Yes I have used the High IMP jack a little, and I agree with your findings but have been staying away from the Hi-z jack, I will give it a longer try tonight.

If you do hear back from Jack please post.

I don't understand.

Your mini-i is this? http://coolfungadget.com/store/index.php?route=product/product&product_id=55

That's the one.

Just to make sure that your PCDP is putting out enough voltage,  could you try another source?  MP3 player, or something that you can connect to your Hafler aux inputs?  If you have another player that has optical out, .maybe try that also.   You should for sure be getting mucho volume from your spkr terminals. 

post #2451 of 13016

Sorry guys but I think I wasn't very clear.  I am getting plenty of volume, just not as loud as I imaging a 100w amp would be.  It is way more than my ears can handle but I seem to recall some of my other headphones can sound like PC speakers from the LD MKVII+.

Are you using the Mini-i in headphone amp mode? If so, power it down and go to the line out/DAC-only mode by holding the knob in while powering it back up, then you can turn the "VOL&HP" to "OFF". You may be double-amping the signal. My Alesis 45wpc amp can't go comfortably past 11-12:00 with the HE-6, and I usually start at 9:00. I haven't tried it with the Mini-i yet, but make sure you are in DAC-only mode with the Mini-i (so  the volume control is defeated), not headphone amp mode. This assumes that you have the option of controlling the volume from your music source, of course.

post #2453 of 13016

The signal going to the Mini-i is optical so that is why I am using the Mini-i as a preamp.

@sunneebear. Do you have a headphone amp (not a portable one)? You can plug any source into the input of the headphone amp, and then use a 1/4" or 1/8" to rca cable (depending on your headphone output port) directly to your L/R input on your amp, just to try another option to see if your chain is the cause of the problem.

 

In other words, before I got my Dared monoblocks, I used (and this is how Fang used his Transcend amp out of his Meridian or DVD Player at Canjam on the less efficient HE-6 prototype) my EF-5 home amp. I took my left and right output of my Esoteric DV-50 using a pair of regular interconnects into the left and right input on the back of the EF-5, and then took a 1/4" to RCA cable from the headphone out on the EF-5 to the back of my left and right inputs of my Adcom, and then the speaker taps of the Adcom to the HE-6. The EF-5 acted as a pre-amp and volume control.

 

This is just a suggestion to see if your current setup is screwing you up somehow.

How do you like the sound of the Adcom 545II?  I was planning to get a used 535II to drive the HE-6.

Yes I can try other set ups.  I am just in a bind at the moment and do not have the time and access to my gear. 

 

I not familiar with the specs of the amp and the math of matching it with the HE-6 but could it be just that.  Impedance or something along that line?

 

I think Fang brought a Threshold 400 or something.  That was one of my other early schemes for the HE-6.  A Nelson Pass design class A amp.  Pass labs, Threshold or Nakamichi.

Right now, I am using it to power a pair of Harbeth Monitors, which are incredible speakers and it sounds great. I have had the 545 since 1993 (1st thing I bought the minute I left my wife tongue.gif ) along with a GTP-400 tuner/pre-amp, and it was a great amp for it's time. At that time it was still made here, then in later years they outsourced their build, and it was said that the quality went down.

 

I would checkout what year the transition was, and find out what year the 535 you're interested in was built. If I remember correctly, the 535 was 60 watts so you wouldn't need an impedance box. The reason that I remember is because I bought a 535 from Harveys in NYC, liked it so much, I took it back to the store and bought the 545 (I really wanted the 555 but couldn't afford it at the time).

post #2460 of 13016

That is why I think the 535 would be a good match for he HE-6.  60w, small size.

 

Ah yes, the GFA-555.  The amp that I first heard my favorite speakers on.  Another Pass design.  The guy sure gets around.
