I'm a proud owner of a pair of VAC Reissue Model 9's and hope there are other owners out there of either the original's or the VAC's from 1997/1998.
I retubed my pair with NOS Mullard XF2's and currently have a nice quad of Amperex PQ 6922's (1960's) in the line stage. The 6922's truly make the soundstage 3D. I also have some 7308's that I roll in now and then, but they're near the end, but still perform very well indeed.
At some point I want to try some Pinch Waist CCa's as I here they can be magical, if you can find them that aren't too microphonic.
