I have used ARC Reference 3 with SMc DNA 1 with great success. So, ARC Ref 3, 5, 6 and the SE versions should do very well. Perhaps other 6H30 tube pre's would do as well, like BAT for example. Be careful with impedance matching. PASS are terrific amplifiers for your stated purpose. Good luck. Enjoy.
What tube pre-amps pair well with Pass amps?
Does anyone have experience with this? I'm running Focal Sopra No. 2s and I understand the Focal's pair nicely with Pass amps. Any tube pre-amps you'd recommend for consideration? I like the classical rock, but am gravitating more to jazz, classical and vocals. I just want to try something new. Thanks.
