At this point, I've narrowed my AVR choices to Harmon Kardon's new AVR-525 and Nad's T752 (with the Denon 3803 close behind). Yet it's hard to compare the sound of the two. I was wondering if anyone here has experience listening to the latest by both? I love the sound of the Nad, which I've listened to a lot. Several dealers told me the company has ironed out design and quality-control problems it had with the previous line, but the Nad isn't exactly laden with features. The T752 is a 5-channel AVR weighing 36 pounds. The HK's I've listend to in Circuit City, but it's hard to get a good read on its sound with the crummy speakers they are hooked up to. I've heard some early glowing reports on the sound of the HK, which some like better than any comparable receiver. It's a hefty 44 pounds, with 7 discrete amps (I would use the back ones for a separate room). The HK is also quite feature laden. From what I can tell, it's sound is sort of in between the quality of its flagship 8000 and its earlier 520. Any thoughts from knowledgeable folks here on the similarities/differences between topline HKs and NADs?
