Once I unpacked the unit, I had it set up and running in under 15 minutes. I ran a PS Audio DSD Perfectwave DAC into input 1 and an Oppo UDP-203 optical disc player into input 2. There are upgrade modules available from Fezz to make the amp Bluetooth capable or to add sub outputs (not included on my review sample), but I used my Perfectwave as my streamer and most of my listening was done via Qobuz. I will not go into an essay on how tubes affect the sound quality because Dr. Johnson gave a comprehensive treatise on it when he recently reviewed the Octave Audio V 110 SE integrated. The irony for me is that I just recently purchased a Benchmark AHB2 amplifier which outputs virtually no distortion even at full rated power (.0003%). When using a tube amp, having some euphonic secondary harmonic distortion is part of why one chooses a tube amp. I enjoy the sound of each amp, but I want to use a low-distortion amp for critical listening to review various products.
