For last couple of years I was playing my DIY TVC on 6+ settings . Today I wanted to check how it would sound on unity gain and the sound became somewhat confused and sort of out of phase sounding .I like the unit, it makes rather pleasant noises but I recall now that when I took it to a friend with modest passive pre (resistors or good POts) we didn't noticed much of a difference (system was pretty good ) .The S&B TVC is a mark I version . Additionally I bypassed TVC and run the interconnects straight to amps from phono pre .It sounded like it is louder with more bass and dynamics than trough 6+ settings . Something is not kosher . Phono pre is Hagerman Cornet 2 with oversized output cap (from 1uF to 2 uF) and amps have 250k imput impedance cables are 1 meter on each side. I bought the TVC used , maybe they are magnetized ??
