I agree with Mwilson above. To add to sound characteristics, the generic EL34 is usually more "neutral" than the 6550 (that's warmer). I don't know the FU29.
OTOH, I'm not sure about getting away with 2xEL34/channel...
For classical, you need detail and dynamic capabilities and energy. Room acoustics aside, speaker specs should be considered carefully: yr 87db spkrs will give a nominal ~70-75 db at listening position. A ~45W/channel amp should yield (nominal again) ~16db (spl) swings from 1W before clipping...
i.e. ~86-90db at listening position before clipping. Not much!
I'd suggest more efficient spkrs for the amps under consideration.
Finally, a side question: why relegate the Jadis to a 2nd system? Is it the Orchestra? It's a good amp, and expensive to improve upon! (IMO, etc)
