That’s not how I do it. I do though have a list of the amps I’ve had in the past (about 100 now), tried countless others, and of course what I have now (26 amps). Many of those amps were really good, but I keep gear that I feel is unmatched to me (of what I’ve tried) in what it does. There are many times where a certain amp may be the best I have for something and then later come across another amp that’s just better. When an amp becomes obsolete for me it then becomes a zero for my intents and purposes even if it was a 10/10 before I got the amp that sent it packing. To be honest, fwiw, the only amp you mentioned there that’s a good amp to me is that Wizard. If we were talking though blueface, Purpleface, Rev 1 Uber or ‘80’s SLO would be another story. Not trying to sound snobby or condescending, but that’s just my opinion
I try to also avoid hyperbole or extremes when describing gear whether it’s for sale or a NAD thread. If I say it’s the best or something extreme like that it just means it’s the best of what I’ve tried at the time and I mean it. The only high gain amps left for me to try right now are a Larry, Hermansson and MLC Silenoz, so I can be more confident if I praise gear more highly now
