I have the PS audio bhk pre with my FirstWatt J2. Sounds great. However, I may seek out a Pass pre after new year.
Exploring Preamp options for the Pass XA25
Please feel free to share preamp options for the XA25. I presently have an Acoustic Research LS-3 and am not sure this is the perfect combination. The Pass Headphone preamp is one option that I'm considering. Tube preamps?
