Passlabs first produces Xs series amp, Xs300 and Xs150. I have a pair of Xs150 so I know the sound. Xs amp has very warm and tube like sound, typical Class A amp.
When they developed Xs preamp, it was certainly voiced against the Xs amp. To balance the sound, Xs preamp naturally has a faster and tighter sound. So if you want to keep Xs preamp, you may want to try the whole set. Xs300 should have enough juice to drive your Q7. My Xs150 drives my M Project very well. |
