I am very sorry but I do not agree with the generalization: When I use the tube rectifier I would get the more 'retro' sound I described - slow, romantic, lush etc. When I switch to SS PSU, it sounds more like a modern SET amp. It is not that simple. You can create a slow, romantic lush sound with SS rectification, and a 'modern'sound whatever that is, with tube rectification. Maybe in your case it works that way.
My advise would be, base your try outs on people who decribe tubes not as good or bad, but on a clear (detailed) decription of how they sound, especially compared to other tubes they have tried. Then, there is only one way, try yourself, experiment. That is part of the fun of buying a tube amplifier in the first place. You can play with it. Tailor the sound to your liking. Have fun!
