If anyone has the opportunity to audition this innovative phono stage, I highly recommend it. By innovative, I'm referring to its use of current injection, which eliminates compatibility issues associated with impedance loading. This unit replaced my Herron VTPH-2. . .the improvement in SQ is significant: clarity, tonality, spatial presentation, etc. Plus, being solid state, I leave it powered continually so it's always ready to play. The only potential "negative" is that it only accepts balanced inputs. No big deal, as I had my tonearm re-terminated accordingly.
