BTW, I already borrowed a demo model, so I have heard it. I don't know all the features yet and I haven't checked out the AD converter part.
I have tried lot's of dac's and I would call this dac (i went into my kt88 amp) high fidelity with depth and cleanliness. It sort of reminds me of the simaudio high end dac (around 1.8k) i once heard. I would not say a lot of "air", but clean and trueness in depth to the sound. Most revealing dac's I heard had a mediocre bass response, but the lynx is full bodied and rich. That is one of the things that sold me on it.
The headphone amp (which uses a separate dac) is very "pro audio" to my ears, meaning it has less coloration than my burson (which is also a clean amp). It sounds superb with my q702 headphones, but can be a little fatiguing with bright recordings. I might need to look into some other headphones to darken it up a bit for those times I want to color the sound a little.
Once I get a new mic preamp I will check out the a-d converter, which should be excellent.
