I would NEVER spend more on tubes than the amp cost. There are plenty of modern tubes that sound perfectly fine. The real issue is with driver and preamp/phono amp tubes and that is noise. RAM Labs has super low noise versions of many of these. I have his super low noise 6922s in my Audio Research PH 3 SE and boy are they super low noise.
Very impressive. He goes through 100s of tubes and hand selects the ones with the lowest noise. His tubes have easily half the noise that my NOS Telefunkens did which I have already sold so don't get horny.
