So tubes really don't sound any different than a Solid State amp? I know they can be made to sound transparent but I assumed most tube amps were not going to that , as it is just a worse amp then.
That's probably the best answer.The only reason to use tubes is because you WANT their distortion.
The very best of tube designs can do very well as preamps, power amps suffer more from the transformer-speaker impedance interface, making them sound different depending on speaker load.
Noise, heat and lack of long term reliability being major downfalls.
But very few new tube circuits are designed to sound "transparent", that's not what their the marketing hangs its hat on. If they don't add that special (distorted) sound, why bother?
