Im looking to purshase an amp for two grand and narrrowed them down to these. I have the Divas 6.1, R3 and the C3. I am really considering the Grande but Sherbourn seems to be on top of everyones list. I cant find the 5/1500A any cheaper than 1899. Can someone point to me where I can get it cheaper because if so then I would by it. The Outlaw 770 seems to be a good amp but no one seems to have reviews on it. For the money that seems like a better deal. Havent decided on the per/pro. Right now im testing the speakers with a Onkyo 797 reciever and a H/K avr320. The 797 seems to be weak in power inspite of its 100/wpc. The avr320 sounds better but lacks power as well. Hopefully I will get a more full sound with the proper pre/pro amp setup. Would I be happy with the Grande over the Sherbourn musically and a HT setup? Is the 770 the best bang for the buck? I dont know much about Parasound.
