That sounds perfect, are these amps called zone amps? Any way you can point me in some direction as to where to buy?
There are tons of amplifiers on the market designed for standard 2 channel amplification. I would stick with a standard amplifier though, not another complex product. Just a super simple quality amplifier that meets the power requirements for your speakers, needs and expectations.
I have used amps from Extron (pro models - used eBay, cheap and work well), Rotel multi-channel amps, and Sonance amps. The sonance 260, 275, or 2120 amplifiers are really designed for this type of standard 2 channel amplification and can be found new/used easily.
I can't speak to the actual quality of other models, but there are TONS of 2 channel home audio amplifiers out there. Some are quite 'audiophile' grade, others can be extremely cheap and of poor quality. I like picking up good (or better) models on eBay for less money.
These are the amps I used in my home...

Be aware of models like the Sonance 260x3. It is a 6 channel amplifier, but doesn't give individual inputs to drive them separately, but here is some stuff...

The Niles 275 in the link above is a solid product that may be a really good deal.
A model like this is something I might use, but I would also build a RCA unbalanced to phoenix block balanced connector which is something I'm familar with and I own a ton of Phoenix blocks already.

It's nice because it is under 2" tall and standard 19" wide. Also nice that it can be rack mounted (ears are removable). It has the 4 channels of amplification that you need.
