My system: Shanling SACD, Audio Research LS25 Pre-Amp, Rogue 150s mono blocks, and Gallo Ref.3. I'm wondering if I'm better of with a Rogue Pre. to match the Rogue 150s.
Is your LS25 a MKI or MKII version. I currently own the MKI (with NOS 6H23 6922 tubes) which I prefer to the MKII version with its FET/6H30 hybrid confguration.
With the 6H23 NOS 6922 tubes, my system is dead quiet with the LS25 volume at the maximum setting for CD playback. With my Phono playback there is a very slight hiss with the volume setting at the maximum. For replacement tubes you may want to contact Upscale Audio and talk to Kevin Deal.
