Hi Mudflap,

Your guideline obviously is the Sensitivity of your speakers 88.3 dB.

You mention you are interested only in 2 channel

Forget any 5.1.

Get yourself into Stereo Amps!!

I'm not familiar with your speakers but I'll bet a nice 'tube' - 'valve' - amp of 10 Watts would make them sing sweet.

If you want transistor amps then aim for 100wats per channel.

Forget about 5.1 if you want stereo.
