Hi guys,

Many suggested me to test AV receiver vs. stereo Amp for below reasons:
1. My NAD 3556BEE only has 80W power, no Sub pre-out. So I have to run full range on my M22s even though my EP500 is very powerful.
2. AV receiver could create/restore more realistic music for better experience.

I did a test today but not satisfying with the results.

Got a second hand Denon AVR 1802/882 and run M22s and sub. However the receiver couldn't generate the same level of detailed,warm, controlled bright sound especially on the high range. The sound is not bad in general and at least better than my expectation. But certainly not as good as the stereo amp. I set the receiver with pure stereo, tone defeat mode. Use the same CD source.

What is your experience and suggestion? Maybe I should use a more expensive receiver? I am thinking to connect receiver front pre-out to NAD line-in to see if there will be any difference.

Thanks.
