I own this amplifier, one of my all time favorite. I switched to Triode (it can be switched from an experience with Conrad-Johnson amps technician) and the results are from B+ as it was to class A rating. Even more detail retrieval, more transparent with excellent dynamics. Bass in the same league as before switching to triode. My amp is the MV60SE. Also tried Tungsol's 6550 and Gold Lion KT88 with excellent results and better than ever soundstage. In triode mode the sound became more precise and insightful without any sign of stress on my Proac speakers. The soundstage also opened up even more than before. I mate this amp with both Placette PVC and Classic M8080 preamp with excellent results. I will stay in triode mode, preferred with any type of music for its enhanced resolution, detail, venue reverberation and liquidity.
