There was a significant jump in sound quality from the LS 27 to the Ref 5SE in my system. It uses 5 6H30s and the 6550, which isn't that many.
Audio Research Pre-Amp advice
Hi, what would be a good used Audio Research pre-amp that has a remote, that is overall very musical. My budget is under 6K? I really don't want any Ref. pre's because too many tubes. Also something not too old, I do not want to have to bring in for service. I welcome and appreciate any advice. Thank you!
