They're both good products, you are the only judge for what qualities you will find pleasing. Some years ago I owned a McIntosh 2205 and loved its power and its looks, not to mention it was built like a tank. My opinion is that you really wouldn't be making a mistake with either McIntosh or Proceed.
Mcintosh Vs Proceed
I am currently looking into purchasing a new amplifier in the 300 watt range. I am looking into the Mcintosh MC352 or the Proceed HPA2. I will be using it mostly for music, but also movies. I am currently using Canton Ergo 122's and a Sony Digital processor. I listen to all types of music mostly classical and soundtracks.
