hey guys. this is my 1st post so here goes. i am building a new house and figured that's a good reason to upgrade my system. currently i have: -onkyo TX-SV525 60w (F/C), 20w (R) -infinity SS2005 125w (F) -infinity CC1 80w (C) -infinity LMPS 80w (R) -sound dynamics ths-10 sub with the new house, my funds are seriously being stretched with new appliances, landscaping, blah, blah, blah. my budget for a new receiver is $500-600. my living room is going to measure 14x21x8 (carpeted). from what i've read in the threads here, i am considering the following: -yamaha RX-V1400, RX-V740 -harman kardon AVR-330 -onkyo TX-SR601 -denon 1804 i don't know alot about all of the technical stuff for setup and whatnot. i will use the system for 98% home theater, 2% music. i've read about recommendations from harmanaudio.com, but am more than a little concerned about a refurbished receiver. any thoughts? also, what are your thoughts about purchasing from an online dealer (etronics)? they seem to be significantly cheaper than locally (but no warranty?). thanks for all of your feedback, it is VERY appreciated.
