My suggestion: Ask Jan Vigne. He probably won't recommend one specific brand or model, but he probably knows of several models that will work well with your 4 ohm speakers. However, you should include what your priorities are in terms of volume, sound quality, etc. Also, the number of watts per channel your amp develops has little to do with the volume potential of your system or how well it will work with your speakers. The sensivity rating of your speakers will tell you more about volume. Having an ample power supply is always good, especially when dealing with a 4 ohm load. You may want to put autoformers between your amp and speakers. AFs will give your amp a consistant 8 ohm load regardless of your speaker impedence. The cheapest autoformers I've seen are $450. Something to consider.
