Plank,
The x-150 is an amp, and yes, I run straight into it from the lynx.
I agree that it does produce a simple chain, and the volume control stigma about losing bits, etc. just doesnt bear out in listening.
THe Lynx sound is a bit hard to describe. It is not analytical at all to my ears, yet it is very detailed, but still very musical. It is also very neutral and clean but still gets the toes tapping.
I use a program called ACXO as a player, since it is designed to offer digital crossovers, and room correction. It is pretty basic in that it was designed to mimic a highend cdp. So it only does .wavs (with cue sheets) and no playlists. But, it will oversample to 96, has ASIO built in, does cover art, crossovers, and room correction. I primarily use it because it is super simple to setup.

I also use foobar because it is more flexible and handles different formats and playlists...but, is a PITA to configure right...so I haven't really made the transition to foobar. This is an ongoing process.
Overall, I love the computer setup, and the sound quality is much better than my cdp/dac combo, and I am off the upgrade merrygoround.
