Tell me if i got it wrong..

Wrong,
The digital signal circuitry can be done with tubes too, but very ineficient since they aren't fast enough on higher freequencies.

Transistors as well as tubes can produce digital and analogue signals as well(in fact there is no such thing as digital signal inside the active element tube or semi-conductor -- it's just only convention that sampled analogue signal is considered to be digitally coded and can be used for the the "portion processing" depending on phase and offset position of a certain sample).

The main difference (visit www.vtl.com) is that tube circuitry is much simplier, the output characteristics are more linear i.e. do not require deep neg. feedback. And the result is less circuit elements on the signal path give a possibility of a better and natural transparency.

The other difference is derived from linearity of tubes' output characteristics, that gives a possibility to use them at the full power without clipping. Saying simply, tube power is more efficient than SS.

SS advantages:
1. No need for an output transformer to match impedance(very very important!)which makes SS more quiet.
2. Less harmonic distortions which are basically derived from the first advantage.
3. Larger possibility of gain with smaller number of active elements(usually SS have more gain than tubes).
4. Transistors are tended to have a lifspan 100x as tubes so there is no need to replace them every couple of years.

I do sacrifice for output transformer hum in my VTLs but I do gain natural voice and rather detailed highs than harsh ones on SS.

Chuck, this mostly have nothing to do with tubes or SS rather than in type of amplifier's operation (Class B amps as an example or push-pull, eliminates even harmonic distortion components).

Harmonic distortions aren't realy important if the're lower than 0.4%

The MOST important thing for the music reproduction is an ansable of your components with speakers. Carefull analysis and/or listening to every component is the way to acheive the most desirable music reproduction you aim.

Bringing up tubes to drive your speakers will be just only 2 cents

Hope you follow...?

...yes, I've ment ansamble(lake a band),Subaruguru. Class A is a picky issue in designing amplifiers. In the SS case it's very inefficient, although it is the way to get tube-like output. If you get Pass Aleph 6, you will be OK in the winter time without heater but what about summer? Besides for 60 output watts it consumes ~500watts from your power socket! To acheive a clear performance in the class A the active elements has to operate in small signal regime. Theoretically only small signal output characteristics of a transistor are linear. It means that Class A is good for a small input signal... That limits these amps in terms of dynamic performance.

If I would go for Pass I would take Pass X350 or higher power models. (in fact I wouldn't go for lower than 225W/ch SS amp)
There are Plinius models that can be a good match and more valuable financially.
Pass discondinued to produce class A amps and Pass X... line is already class A/B. (not "Stereophile class A")
Class A/B in my opinion is better since it's more music-independed.

Did I controverse myself previously? NO! The harmonic distortions of tube amps are solely from output transformers since the're not as lenear as tubes The higher output power tube amps used the higher amplitude of unwanted distortions will be produced. Also as I've mentioned before, these distortions are neglectable if placed next to number of advantages we gain from tubes.
