You auditioned a setup that is not even close to ideal for orchestral music. Even if the speakers have an impedance that is easy to drive, 93 dB speakers still require more than a few watts to get them going. I wouldn't dismiss low power amps based on a single audtion. Paired with the right speakers those amps will sound incredible with more than jazz and blues.
The pluses are just what you heard, incredible sound. The minus is they must be paired with the right speakers, if you can call that a minus since matching components is a must with any set up.
These things are easily obtained with low power amps. One solution is to use a powered woofer for the lowest octaves. Avantgarde and other highly regarded speakers go this route. Take a look at my system. It delivers all you asked for and more.

For myself its not something I'm interested in as all my listenings are classical, and I want the orchestras to sound full rich, dynamic, that is the low and high end extended.
