Not sure... how much power do your amps draw? I have a Quintet in my Home Theater system and everything including the 100Wpc Onkyo receiver is plugged into it. If anything, the bass became more taut and articulate when the Quintet went in and I didn't notice any loss of bass.
But if you like the sound of your amps better plugged straight into the wall then maybe that's how you should do it. Your amps might draw much more power than mine.
On the other hand, I use a PS Audio UPC-200 in my bigger system... I believe it may have higher current capacity than the Quintet, so perhaps you could try one of those (run in its high-current mode) on the amps only.
