Parasound HCA-3500 to Proceed HPA-2?


I currently have the Parasound and am wondering if this is an upgrade or just a step sidways? The Parasound seems to win the specs game but it cost much less new. Also i would like to inquire to all proceed owners about the durrability of the hca-2. (I know proceed has an upgrade out for this amp that, from what I understand, fixes durrability problems)

Do you think a Classe preamp would help tame the parasound? (as a side note i have started looking for new speakers for a two channel setup, i will probably keep the paradigms for home theatre and slowly convert them over to whatever speaker i choose)
What room treatments do you have? This can make a big difference in the presentation of any speaker.
The speakers are located in a guest bedroom which contains one twin bed, an love seat(my seeting position),and an armoire. What room treatments do you recomend? how do I position them?
do a search on audioasylum and here,about parasound,bob crumped talked alot about this issue,,i sold mine cause i coudnt take it..there is a mod to fix it but i didnt do it
