Just really simple and clean, but sounds amazing on my ST-120 powered VOTTs. I am now in the process of ripping a collection of some 400+ CDs to lossless files (flac) on the HD.

Looks good mate, let us know how you get on 
What else is in your audio setup. Those speakers look interesting.
The speakers are my version of Altec’s Voice of the Theater A7 with homebrew Linkwitz-Riley passive crossover networks.
Amplifier is an ST-120 with KT-88 output tubes. I also have a mix-match bunch of hardware making-up my home recording studio (Cakewalk and Band In A Box software). My studio preamp is tube / solid-state switchable and was designed and built by “yours-truly”. Studio powered near-field monitors are Edifier R1280T
My DAC and CD transport feed directly into the ST-120 amp via just a selector / stepped-attenuator (no other electronics in that chain).
Calibrated reference mic is a MiniDSP UMIK-1.
Built “on the cheap” over quite a number of years, but I think the sonic performance is quite impressive.
Listening space is 12ft x 34ft, treatments are carpeted floor, acoustic suspension ceiling (fiberglass), medium-heavy wall to wall drapes across the rear wall behind the speakers and just your average living/dining room furnishings.
Here are some pics:
