Jay ,
You can spend yourself blind sorting through the different class A components that are available. There are some great suggestions in this feed but consider the efficiency of your speakers and go to your dealer to listen on a few options. Some dealers even let you take items home for a test drive which may be best. I personally settled on a small flea wat amplifier that only puts out a couple of watts per side, but this is married to a set of really high efficiency Klipsch speakers. Unfortunately it's going to be different for every user. For your budget however I would encourage you to consider Schiit Freya+ and a pair of their monos! They can drive most speakers and they put out pure class A to a point. With class A you will find that you only are using the first five or 10 Watts anyways so don't worry so much about having a ton of power. The nice thing about this company is they are a US company and they will let you test drive in your home no questions asked. Hope this helps and happy Sonic Bliss
