Give Reno HiFi a call and ask for their thoughts. I have a Ref 3 with a pass labs 350.5 and it works well in my system. Good Luck.
Pass XA Monoblock Amps with Audio Research Preamps
Have any of you Pass XA.5 owners matched up your amps with the Audio Research LS-27, Reference 3, or Reference 5 preamps. I own the Pass XA100.5 Monos and appreciate your thoughts related to this combination of a solid state amp with tubed preamp. Thanks Stephen
