Oops hah reading too many threads I meant to put the OPA2227 for the bass channel and the LM4562 for the other channels.

so then 1 x OPA2226 and 5 x LM4562?

Sounds about right. The Opamps are dual amps so each opamp works for two channels. If you need 6 you must be able to change your Line_in opamps aswell? Is, and I say if you want to save a little cash you could: USe the OPA2227 for the SUB/Center channels, use the LM4562 for the front channels and use OPA2134's for the rest. The LM4562 will cost you about $5 each.
There are lots of ways you could do this mod...

Out of the pdf from Auzentech :

Swappable four high perfomance OPAMP for Output channel, two high perfomance OPAMP for MIC Input - increase gain level and improve SNR


So yes I can change my line_in

Do you use the Mic_in? If you don't use it, don't bother swapping it. Your choice though.

Nope and I didn't 2 of them were for that so I'll just get the 3 of the 1 and 1 of the 2227 for the sub.

That is about right. Make sure you get 8 Pin DIP versions.
