RE: Went to a hifi show today in Switzerland...

The engineer didn't say HOW the transistors get low distortion...it is with copious amounts of negative feedback! Read Crowhurst and others about the effects that has on subjective sound.

Your numbers, especially for preamps, are way off...there are a number of good tube preamps on the market that will produce less than 0.2% distortion and even a goodly number of tube amps that will do so at low power.

Low distortion is a red herring anyway when pursued with the wrong strategy to reduce it (i.e. lots of negative feedback).

Triodes are MUCH more linear than any transistor...its fact not speculation. Combining more and more non-linear devices does not make a circuit magically more linear. It is ONLY through the use of negative feedback that it a complex transistor circuit can be made to behave.

Which hybrid did you use? Give names or stop pretending.

Enjoy your underdesigned JOB...I am sure you will tire of having weak bass due to a weak power supply.
