Has anyone purchased anything from 6th ave?? Your experience would be appreciated. I dont understand how the pricing on the HK line could be so much cheaper than at local stores. IN fact, one guy at a local pro-audio store claims emphatically that HK can not be sold over the internet. I was looking at the AVR430 (at 6th ave) and it was $300+ cheaper than at the stores. Also can there be any comparison made between the HK 430 vs the Denon 2803 for sound quality?? Thanks.
