Parallel Triode amps vs Triode wired pentode amps

Specifically a JJ 322 using parallel 300B output tubes ... do parallel triode present the same matching difficulties of SE triodes in that they are (generally speaking) optimized for single driver speakers or speaker with very simple crossovers??? Or, with the increased power output, do they work well with "average" sensitivity speakers??

In my case, I am considering the purchase of a used JJ 322. Not from a dealer so there is now way to audition at home. I am willing to take the chance on used gear, mainly because it can usually be sold at little or no loss.

My system consists of North Star 192 DAC and transport and Alon Exotica speakers (88db 7 ohm min, 10ohm max), Cardas cables througout. I have used push-pull tube amps (6L6GC, 28w/ch) with very good success but am looking for some of the "SET magic" (knowing a true SET amp besdies an 845 based model).

Have also been considering a Cary SLI-80 F1 triode as an alternative ... any comments on this amp appreciated as well.

Jeff, pentodes wired as triodes are not the same thing as actual triodes. It is not that hard to put triodes in parallel; there are techniques for that and the linearity you get is still well ahead of that of a pentode wired as a triode.

This only addresses that question- there are other things that affect the sound of an amplifier such as transformer or power supply design, so audition is still the best bet.
