VAC owners, sound off

I have a Vac amp, which does have a high gain. I believe
38, as opposed to many other tube amps, which are closer
to 30. I only open my V-C to around 9:00 ot 1/4 turn,
which is loud. The manufacturer of my preamp said not to
worry about this because the type of volume control he uses
in his preamps do not change in sound no matter what level
you are playing. FWIW, I also heard a VAC Ren sig 2 on a
VAC amp, and I believe this sound was also loud at around
1/4 turm. My pramp is not a VAC, but does have 20 db of gain, the VAC's I know are higher gain as well. Not sure of the spec. I guess even though VAC amps have the higher
than average gain, Kevin still uses a fair amount of gain in his preamps. When I heard a VAC amp at a dealers recently, he was using the VTL pre. Again, a higher gain pre paired w/ the Vac amps. Regardless, I do feel it would be better to open up the V-C a bit more and/or have smaller step increments on it as well. Just my related experience, hope it helps. It does seem like a synergy issue may be involved though. You may want to call Kevin,
and let him know your amps specs, and then your amp manufacturer, and let him know the preamps specs.

The VAC has an even lower output impedence than the AH. One of the lower ones i've seen in fact @ 350. Based on that you'd think it would mate fine with my amp rated at 55k input.

My last ditch-resort (prob just confirming the unfortunate known) is to put in a call to Kevin Hayes and go over some specs. Plan on doing that today. If that goes as expected, I'll put this VAC up on the 'gon and use the $ to get something that hopefully synergizes better.
