I currently have 4 HCA-1000A's. I am running them in a complicated configuration using one amp for L front and surr, one amp for R front and surr, one amp for center and one amp for L/R rears. I did this to minimize crosstalk for 2-channel listening. I have Onix Ref 1 bookshelfs all around and an Onix Ref 100 center. They are 4ohm speakers at 88db sens. and not really a difficult load. I run them full range for 2-channel and multichannel music and cross them over for HT. Anyway I am soliciting input on an upgrade. I have an opportunity to get a great deal on a HCA-2003 for the fronts and I am wondering if it will be worth it. I could sell 2 of my 1000A's and have the money but I do not know if it is worth my trouble. I just want all the Parasound owners out there to tell me if the 2003 sounds significantly better than the 1000A. I know it has more power but in my system that probably won't matter too much. Thanks for the input and if there are any other suggestions let me know.
