Imagine what sound quality one can get out of 20-30W amp for the same money one spends for 160W monster. It's very simple. Prices for components (of the same quality) go up exponentially for high power amps. So something has to give, either less power or less quality. Not to mention the planet.
Back to the speaker question. Best speakers for classical music and jazz are single driver speakers. They don't use crossovers hence avoid various kinds of distortions, maintain the full dynamic range... In addition, they "sing with a single voice" so they don't brake instruments and vocals among different drivers with different characteristics, speeds... In classical music and jazz you want piano to sound like a piano rather than an electric instrument. Even better how about hearing the difference between a Steinway and Bosendorfer?
