I'm tending to agree with you O.. As much as I love the WA7, I'm finding more and more the DAC lacking. Although I don't have the Schiit Stack anymore, I remeber/felt that the Bifrost Uber provided more airy sound with greater detail. Pretty evident with Patricia Barber and Eva Cassidy. Even noticing it with Deadmou5, Enigma and Morgan Page. This is with the HD800 and I'm not so sure that it would be as noticeable with another set of HP's.
If Woo ever comes out with an amp only version of the WA7, I'd be really tempted to get it and pair it with at least the Bifrost Uber or something better. I love the simplicity of the WA7 but am seriously considering picking up another DAC. Maybe the Bifrost Uber again, the Bel Canto DAC 1.5 or the PS Audio NuWave. I think I'm going to pull my PS Audio DL III out of my main AV system and giving it a go with the WA7.
Just a sidenote.. running my Black Momentum's out of the WA7 right now.. sound s pretty awesome! Really can expect much more out of a $350 headphone.
