I have been pleased with Onkyo receivers. The bass response is a little thin but overall I like their sound quality. TXDS696 at $699 was an excellent choice for my modest theater system I know several other owner that have not been displeased either. Another option is the TXDS595 at $499, however the performance is a little bit of a down grade from the TXDS696. I believe the HK prices are $599 for the AVR310 and $799 for the AVR510. Sound quality of the Harman Kardon is a little bit smoother in my opinion.
Best A/V Receiver Under 700
I have a modest home theater set up in a small extra bedroom, with an NAD 760. I have not been particularly impressed with the NAD 760 for two channel audio. I was thinking of the Outlaw 1050, or perhaps picking up used amp and processor separates (although I would prefer to keep the equipment down to a minimum to save space, even if the cost is comparable). This system will include three Tyler Acoustics Taylo Reference Monitors for the front and center. I will add the rear channels at a later date. Speaker cables are DH Lab Silver Sonic Q10. How about some opinions on the best solution at a modest price. Thank you for your help.
