I agree with Judit: you owe it to yourself to hear the SA102.
I traded up to the SA102 from an 8200 integrated. For the money, the 8200 is great, but no match for the SA102. The 8200 is rated at 175 watts at 8 ohms, and the SA102 is 125 watts at 8 ohms. But the SA102 is capable of delivering something like 4500 watts at clipping and even the gutsy 8200 can't match that. The SA102 can really swing that woofer like no other amp I've heard (except the SA250).
As to your question, Symphony Sound is theoretically correct, but I admit I can't hear a difference between A and A/B on the SA102. But who cares - this amp is awesome!
