The prototype of the new Woo Audio WA7 DAC/headamp looks pretty snazzy.
The American company has just presented it at the Rocky Mountain Audio (and beer) Fest 2012.
I like the cube design, small and stylish, giving the tube amp somehow more class with the glass top,
than with just letting the tubes stand free as many tube amplifiers do.
It´s a pure Class A headamp, with a full 32-bit/192 kHz build in DAC at around 777 $
during the introduction period, sounds nice.
Some speculate that it will land around 900-1000$ when this period is over.First impression that I have come across says :
It’s warm and vibrant but not dark, and open with great detail and soundstage, transparent, and POWERFUL.
Not Schitt or EF5/6 powerful, but at least 3x more power than my WA6 (maybe as much as the WA6 SE?).
I have a maxed WA6 at home, full of Vcaps and Blackgates upgrades, plus the Pseudo Dual Power Supply Mod,
with $220 worth of tubes, that cost about $1200 with the upgrades and tubes. This $777 amp could possibly be better.
I may end up getting one just to compare to the WA6. I find that my maxed WA6 is great with ALL of my IEM,
plus my LA7000, Ultrasone, Grados, HD600 and HD800. However, although the timbre and tone is great
with my HE-500 and LCD-2 it could use a little more power with these orthodynamics which lack a little
PRAT with the WA6. Jack says the cheap volume pot on the pre-pro model will be replaced with the same
nice volume pot that I have on my WA6.“

Headphone Addict said this, "It was very good with HD800 - I only tried 3 phones with it - the original HiFiMan HE-5, the HE-500 with Silver Dragon cable, and the HD800 but I forget what cable was on them."
