The only problem with VAC gear is the darn Price

However, I can attest that you get a lot for each watt you buy from VAC, meaning a VAC watt sounds more resolute and powerful than it should. I was once powering a 87dB speaker with 30 watt VAC 300B power (more like 28 watts), and it was behaving like 200 watts SS power

Oh, that "something" about VAC's top of the line gear is probably meticulous voicing over years by VAC's Kevin Hayes. He is a like a fantastic cook in the kitchen, perfecting his stew...
