Erndog,
This is one of those situations where you are going to have to listen yourself. I doubt very few if any have heard these two amplifiers in the same system. There are overt differences between the two amplifiers. Tube (output, driver, input) circuit, transformers etc. Very different concept and design objectives. Higher power and cost won't guarantee better sound all the time. This is definitely going to require listening to both amplifiers with your speakers. Anything else is speculation, although it could yield interesting dialog.
