Ok , for some reason I thought those were digital inputs. 
Thanks I appreciate it.

I thought the same thing when I had the V200 loaner here because they are black and not red/white, but I figured it out when mix-matching components for my review.

   My Soloist is rated at 4W in 16 Ohms.
and the V200 is rated at: 
Output Voltage in 16 Ohms
  
  
  
 4 Veff
Output Power in 16 Ohms
  
  
  
 1000 mW
 
So am I correct in assuming the V200 is rated  1W at 16 Ohms?  So the Soloist is about 3x higher in output power? 
Hum, I though they were both similar in power.  
Does the V200 do well with the LCD-3?  HE-6? other difficult to drive HP?

Depends what the headphones resistance is in ohms. With the 50ohm lcds, the soloist measures at 1.8W and the V200 states 2.7W.

This.
 
Max output is different for each amp based on topology. Take a look at the SPL Phonitor or Auditor - they do max current into 600 ohm loads, while low impedance headphones only see a fraction of that.
 
This is a good lesson as to why headphone enthusiasts should have a bit of technical understanding... You might have a HiFiMAN HE-6 and look at the SPL amps and say "max output 1700mW, that should be enough" without realizing that the HE-6 will only see ~1/3 of that.
 
The Burson max output at 16 ohms doesn't quite seem ideal to me. Not many headphones dip that low. But it is generally good in that it delivers more current into lower impedances.

Thanks so much for nice summary, project86. I have a lot to a learn.

Does anyone have an updated picture of the new 24/192 USB module? I see its advertised on Thomann.de but the picture still looks like the older 24/96 USB module as it has the Tenor 7702 chip and PCM1793 DACs on it.
 
If anyone has this module then I would love some impressions on it! I'm quite eager to pull the trigger on a V200 with the USB module if its quality is anywhere near that of a stand alone DAC, as I would have to sell the Concero to fund the V200 purchase.

Here is a picture: http://www.head-fi.org/t/705318/violectric-hpa-v281-vorsprung-durch-balanced/30#post_10355816
 
Compared to my Meridian Explorer using Sennheiser HD 650 & Violectric V100 I would say that:
- Bass are more present with the Explorer
- Violectric module is more detailed / less smooth (same impression I had comparing Dragonfly v1 with Explorer)
- Difference is definitely not night & day
 
There is no problem with Tenor USB implementation on Mac OS X Mountain Lion.
 
I would suggest waiting for additional reviews anyway: hard to give a certain impression.

Thanks a lot for the info and photos in the other link. Sounds like a better strategy to keep the Concero and wait it out for the V220.

So far, i'm loving what i hearing! So much detail!

There is an even earlier version with different faceplate: http://cdn.head-fi.org/8/87/800x600px-LL-8791434f_V20013Front.jpeg
 
I guess everything is the same as Guzmeister's picture inside. Volume knob with white line is older with different volume pot.
