Amps that can drive the HiFiMan HE-6 planar headphones - Page 160

post #2386 of 2714

Asus ST coaxial out to Gung/Mojo stack.  Smooth, clean sound.  Adele is a touch sharp on some songs.  I'm streaming from google music service.  I like it.

In comparison, new LCD-2 sounded like hot trash; still no soundstage.

Can two Lyrs drive He-6 as mono-blocs?
Electrically it might be doable by bridging R-L channels.

Why use two Lyrs though - tube matching aside it'll cost as much (and potentially emit more heat) as a good speaker amp :D

So I decided to completely restore the 2205 internally along with replacing the glass with a new one. I used all nichicon premiums on the driver boards, input rca's and power supply. I also used them mostly on the meter board with the exception of a couple of couple panasonic fc's. I replaced all bad or out of spec resistors, diodes and transistors along with a few ic's and the results are pretty stunning. It's been said by a few over at audiokarma that a fully restored mc2205 is on par with the modern mac stuff. I don't have a modern on here with me, but it sounds much better after doing the restore.

 

The interesting about the 2205 is, it's really the sweet spot in the vintage mac line. It has the modern features that are still used in macs today like auto transformers and power guard. I also replaced all lamps in both the 2205 and c39 some custom made led lamps I maded. The bi-pin lamps were easy, but the bayonets were just a tad bit more tricky. Oh, and I also the glass on the c39 along with deoxiting all of the switches and pots on both, and of course I had to re-bias the 2205 after replacing all of the caps.

 

So the total invested ended up being just under 1200.00 which is a steal for the sound I'm getting now. I'm trying to decide what I like better between it and the 500c. The mac rig is just on the warmer side of neutral and the bass is just monsterous. The mids are buttery smooth, very rich and organic. The 500c on the other hand, although a tube amp, is the most neutral thing I've listened to. It has more air and sparkle. Transparency, sound staging and imagine on both is about equal, but the 500c don't quiet have the slam as the macs. But the mac is the best solid state pairing I've tried so far. And the fact it's even competeing with the 500c really says a lot.

 

Dude..I kneel before you..Nice fuggin amps, seriously

Does anyone have any opinions on the Emotiva XPA-1L switchable Class A/AB monoblocks? 

 

http://shop.emotiva.com/collections/amplifiers/products/xpa-1l 

 

I am currently using the Emotiva Mini-X a-100 which I feel drives the HE-6 quite well compared to a number of top of the line headphone amplifiers, but wondered if the XPA-1L might be a reasonable increase in quality. Ha, there, I avoided the dreaded "worth it" which I know is extremely subjective. But for one I would hope that I am getting about 99% out of them with Class A monoblocks. Also I do not know exactly how it breaks down, and perhaps I would need to email Emotiva, but would they put enough power into 50 ohm if in full class A they put 35 watts into 8 ohms? Because if not I might as well stick with the mini-X? 

 

Another reason the XPA-1L actually interested me is because they are not so powerful. It bothers me that even on my mini-X I never bring the volume past 10 or 11 o'clock; I have less control than I would like. Where as down to from 50 to 35 watts and being fed by a WA2 preamp (where at least the volume knob is physically much larger) I thought I might also have more control with a WA2->XPA-1L chain. 

 

Any thoughts would be much appreciated!

Together they will cost around $1.4K  I thought about them before they was released as well.  All together different beast compared to the mini-X .  I'm sure they will sound very good.  I have the old UPA-1 mono blocks (Home theater).  I've used them with the HE-6 and had very good results.  So these should give you at least a marginal gain in SQ but a larger jump over the min-X.  Nothing to it but to do it.  :biggrin:

How did they sound compared to your First Watt?

Well for me, all the Emotiva amps I've tried with the HE-6 has been a little on the bright side compaed to all my other amps.  Where the F1J sits right in the middle.

 Do you think the WA2 as a preamp might smooth the treble some?

I have the same experience with Emotiva amps too. They are noisy, which contributes to the brightness. The excessive gain really works against them.

Not sure how the WA2 act as a pre amp.  It needs to be silent and warm but able to provide as much detail as possible.  You don't want your pre to round or blunt your leading edges (dynamics) you still want them to be crisp but not bothersome.

So would you be of the opinion that XPA-1L monoblocks would not be that good of an HE-6 End Game Amp?

Lol, thanks. It's up there with the best I've heard the he6. Narrowly beaten by a couple of other amps I've owned. But may just be the most fun, the bass is just thunderous!!

I've tried the WA2 as a preamp for Stax 007/007 and liked it. It smooth the  treble and gives an extra hint of warmt. Very pleasant sound indeed.

I can't really comment on that specific model, but it still has 29dB gain like all the others I have heard, and you can hear the noise even with 84dB inefficient speakers. Unacceptable IMO. I wouldn't chance it.

Yeah if McIntosh has retained their house sound through the years, the current-production SS amps throw some serious bass lol. Very warm, but not congested.
