Amp recommendations for Audeze LCD-2

Yeah, can't help there, as I've never heard the Violectric in any setting. But both the WA6 and Concerto do a good job with the LCD-2, although I think I slightly prefer them with the Woo.

Thanks.
 
V200 impressions seem to be a bit thin on the ground. I'd also like to hear opinions about the optional DAC.

I have a V200 on order and it was received/in stock as of today and sounds like shipping out to me Monday.  Probably see it by the end of the week but I am still waiting for the LCD2's so who knows when i will have an impression.

I've had my LCD-2's and V200 for a few weeks now, and have been very happy with the combo. I can't find any major faults, which I feel is the best compliment. So far I find the V200 to be quick, dynamic, and musical. I'm enjoying it more then my DNA Sonett with these headphones.
 
Haven't tried the build in DAC. One of the days I'll give it a run.

Hmm... I've been looking into getting the LCD-2s and a matching DAC/Amp, and you guys are very helpful so far!  But, one of the devices that caught my eye was the Lavry DA11.  Has anyone tried the LCD-2 on it?  The 24/96 USB DAC plus balanced and unbalanced output has me all jumpy for it.  Or any other $1000 amp, $600 DAC combos that would treat it right?

Yeah would be interesting to hear how the DAC of the Violectric compares to level of DA11 or Mytek Stereo 96.  I guess it wouldn't be quite that good?.
 
Someone, I think Kwkarth, said that the DA11 had enough current to drive the LCD-2's but would it sound as good as a proper headphone amp?

 The V200 uses discrete outputs vs the V181 which uses Buf634s according to the Violectric data sheets.  I would take the V200 over the V181 any day.

 
 
 
The tech data doesn’t convince me that the "discrete tansistor" V200 is a obvious “any day” win over the V181 with "Balalnced output" (I prefer the term "Bridged")  for the LCD-2
 
Looking at thd+n the buf634 looks to be holding up better with lower Z load (comparing 100 and 32 Ohm thd+n  as bracketing the LCD-2’s 50 Ohms) - it appears likely the V181 would be better on this spec at 50 Ohms than the V200 driving the LCD-2 to 120 dB SPL
 
2 dB more power from the V200 into 50 Ohms isn't so critical when the V181 can already drive the LCD to 124 dB SPL but this is an advantage in the V200's favor for those who believe in extreme dynamic headroom - but the automatic objections and hostility I face when trying to point out headroom requirements on head-fi suggest most members won't think this is a meaningful difference
 
amplifier damping factor beyond a 100 isn’t a audible issue with any headphone, even less so with the LCD when you add the knowledge from Tyle’s impedance measurements that the LCD-2 shows a flat, presumably resistive load – as expected from orthodynamic driver physics
the "impressive" 800 damping factor # for the V200 isn't a meaningful differentiator vs the V181's "only" 250 with the LCD
 
The touted V200’s discrete output's “60 V supply” "advantage" isn’t showing up in the numbers in the table for 600 Ohm load either
 
so is it just the word "discrete"? – the Violectric site product descriptions say both use op amps for the pre-gain and the numbers suggest the both the V181 and V200 outputs are also inside op amp feedback loops – although that certainly isn’t clear from the product descriptions
 
given the hype and predujices of the audiophile community I suppose the words “discrete transistor” is worth the extra ~US$100 in resale - but the the V181 has "Balanced" outputs - which gets a lot of street credit here too
 
but I really doubt the difference could be heard ABX

Why would I tale the V200 over the V181?  Free DAC.  Bridged output, especially when their single buf634s for each rail, seem inadequate to me.  If they were stacked and bridged, then I would be more interested, given the characteristics of the '634.
 
Oh, and "balanced" outputs?  WOOFLE DUST.

I'm in the same boat...V200 on the way and on the list for the LCD-2...

I talked to Robert over there who is the US distributer and he said there is a large dynamic difference between the V100 and the V200.  I looked at the numbers when checking to buy one and it looked like the 100 might work.  Many have sold the 100 and jumped up because of the gap between the two.  After that remember that the V181 is based on the V100 design.  That said it is obvious to me that for now the V200 is the way to go, at least until the balanced V200 is released in a year or so.

"USB Eingang optional" means "the USB input is an option" on V181 (and from July 2010 on V100 and V200) at extra cost.

 
I just checked @ the Aphrodite site, and the USB input is optional on both the V181 & V200, but not yet available for the V100.

Here's another one.
 
Has anyone tried a balanced or 3-channel beta22 with the LCD-2 yet?

question: posted this in the LCD-2 thread, but the question seems to have been overlooked. I was wondering if these specs of the M-stage would be able to power the LCD-2? I'm not sure how to read the technical specs. Also, I wouldn't want them to just power, I'd be looking more at whether it has enough power to sufficiently drive the LCD-2s to it's potential. Any help is appreciated.
 
  1. Frequency Response: 10 Hz (-0.3dB) ~ 35kHz (-1dB)
  2. Signal to Noise Ratio: >95dB (0dB)
  3. Distortion: <0.001% (6 mW/300 Ohms)
  4. Input Impedance: 47 kOhms
  5. Output Impedance: Line-out 60 Ohms, Phone-out 5 Ohms
  6. Output Power: 200 mW/300 Ohms, 400 mW/60 Ohms
