Most underrated 3ch or 5ch Power Amp? (NOT Emotiva please)

[bizmord]

I am pretty happy with my sound, but a power amp may produce better sound than the amps I get in my Denon 4311.
My speakers are not too sensitive (Ascend Sierra-1NrT) and will definitely benefit from an Amp.

Now, here is the question. I know that Emotiva is a very well known and loved brand, thus, you also pay for their branding. What I am trying to find is an Amp that will do better than a Denon 4311 Receiver and costs less because it's either an older amp or a not so well know brand that I can find on Ebay. I am OK with 3 channels to drive my front stage or 5ch for all my speakers.

I've looked at Rotel RB-985 and Anthem PVA-5 and those look pretty nice but maybe there are better deals out there.

I know very little about amps as I always used a Receiver and hope you guys can shed some light on this.

Thank you.
