Cryogenic Tubes - Time for a Change

@thecarpathian 

That's a good question. CryoTone removes the original branding from the tube and replaces it with their label. My thinking is if they're providing top quality tubes they would want everyone to know about that. My guess is they're probably using a mid quality tube. Starting with a poor quality tube seems to defeat the purpose. I'm going to replace the (1) blown tube with a similar tube (Psvane) and do some A/B comparisons with the CryoTone tubes. Not because I'm questioning my initial impressions but because I feel I owe it to everyone to follow through with this story. Also, it's only fair to let the cryo'd tubes break-in. 

If it sounds better to you, that’s what counts.

But I would say that if you had been listening to that previous set of tubes for quite some time (as it sounds as if you have been) you hve been hearing, and are experienced with, the sound of them gradually degrading after they were at their peak.

I am thinking it is possible that what you are hearing now (that sounds so good) is the sound of tubes that have not degraded from their peak. For the comparison to be fair and accurate, I would think you would have to have the original sound of those original tubes, when they were new, fresh in your ears/mind.

My original (brand new) tubes are only a year old.

I'm not an expert on tubes but I'd venture to say they're pretty close to "peak" after 500 hours of burn in.

I believe I just got a bad one from Psvane that red plated on me.
