"But can someone who is and has listened to both a Crown XLS and a high-end Class A amplifier in their system tell me how much of a difference there really is?"
A huge difference. I tried a QSC as well. Those amps are perfect if you are building a music/HT system and have a limited budget. You can use them to power your center, surrounds and subs cheaply, so you can put more money into the amp for your front main speakers.
