I have 100 hours on a Herron VTSP-360 and it's settled in and opened up. It adds tube magic and really shows what the XA-25 can do. Speed, power, dynamics, and finesse without breaking a sweat.
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?
