(Sorry for the slight off topicness) @nitewulf In the past year I've had a PS Audio PWD & Directstream, Matrix X-Sabre Pro, Shiit Bifrost II, Audio Mirror T3-SE, Lampizator Amber 3, and ifiIDSD Pro in my house for extended auditions (10-30 days)... all except for the Directstream at the same time. Unfortunately despite the great measurements, I didn't like the Matrix. It just sounded bland and involving. I started kind of dreading when it would come up in the rotation. I chose the Analog Devices based Audio Mirror, which makes beautifully coherent, natural,and real music, with the most three dimensional soundstaging of the group. That's the reason I continue to read about high end r2rs.
