This is a hybrid 2 channel / MCH system with dedicated servers. The MCH server sits behind the rack feeding 3 x DirectStream from a Lynx card. The 2 channel server is bottom left, next to Oppo 103D. Both servers run Dirac Live DRC. All libraries are controlled from iPad JRiver/Jmedia. Amplification is Spectral. Also behind the rack are Shunyata Triton and Typhon conditioners. Main speakers and center are Evolution Acoustics. I have a pair of B&W NT8 Signature in-walls for surround. Just got my hands on a 2 x stereo Job 225 for amplification of Center / Surrounds. Will try the new PS Audio amp when released. Waiting for Ted to deliver an firmware fix for alleged clock sync issues when using 3 x DS in MCH application. I am not using any subs.
