in a not to distant future i will be purchasing a new HT receiver, at the present time i am down to two receivers, the Yamaha RXZ7 and Denon 4311CI. i know that as far as sounds is concerned there is not much difference between the two, (sound can only be improved if you upgrade speakers and not the receivers right?) what i am looking for is anyone of you had any experience with these two models. the Denon is more expensive by $300.00 and Yamaha has more features. although i have owned Denon products before and am extremely happy with the product. would appreciate you imputs in that regard. thanks
