There have been VAC PA 160 monoblocks for sale here on Agon. I had a pair and they were fantastic. Sold them to put in a HT. If I ever went back to tubes these amps would be it. Also the service from the boys at VAC is second to none. I stopped in unannounced when they were in NC and was treated to a tour and a listen to there inhouse system. Upgrades available and their tubes were also fantastic for replacement. I even had my CAT retubed. Great performance for the $.
