Plain and simple.... I am considering the Harman Kardon AVR320 as an interim replacement for my Denon 5800 while it's away for service. After that, the HK AV320 moves to the bedroom/den. Now the question: in my research I keep seeing grumblings that Logic 7 on the HK line is somehow 'crippled'. What are the differences between the HK and the Lexicon implementations? The only info I have come across is that the HK has only 4 Logic 7 modes. Is this of real significance? I will be using the piece with a 6.1 setup while the Denon is away, and then as a 5.1 piece when moved to the bedroom/den. Thanks!
