Valve Amplification Company (VAC) "Vintage" preamplifier MKIII: how does it sound?

I bought a VAC Vintage MK2 back in 1995. I never had it upgraded to the MK3. It is still in my system. I've had a few other preamps and or phono stages over the years to audition and never really found one that bettered the VAC. We use it almost every day. Right now I have a pair of Golden Lion 12ax7's in the phono stage and new style Mullards for the rest. It has been bullet proof since I bought it. One note, if you do by one, the line stage inverts phase. Happy listening
