Stereophile rated the 2200II as Class B and the 2003 as Class C.
Parasound HCA-2003A versus HCA-2200II
I currently own a Parasound HCA-2003A. This 220x3 amp has really been wonderful and I have fallen in love with the Parasound sonic character. I originally purchased this amp for HT and now I am wondering if I should look for a HCA-2200II for 2-channel only duties. My question is for those who have had experience with both or either amplifier. What, if any, are the main sonic differences and how much better is the 2200II. Thanks for all the input.
