hi,
Classical music has a large dynamic range ( 20 db or more) and the problem with some of the speakers listed is that they are inefficent and on the peaks of orchestral sound will send many amps into clipping. Tube amps have an advantage here with softer 2ed harmonic clipping characteriics
When listening at a average level of 85 db a 4 meteres with an inefficeint speaker, say 85 db/1watt/meter 8 watts is needed to reach 85 db at the listener psoition. To reach 105 db peaks will reaquir about 500 watts per channel. Now we are talking mega buck amps.
A simpler solution IMHO is to use more efficient speakers.
good listening
Larry
