Oh come on!
Can you explain, in less vague terms, how "Their power amplifiers are solid and have better resolution than NAD. NAD has good bottom low end, but lack the fine resolution of Rotel."
When it comes to SQ, I don't think NAD takes a back seat to any other manufacturer. That said, I don't believe they are superior to Rotel, or any other reputable manufacturer. Why? Because any modern competently constructed AVR or amplifier will sound the same, when operated within its power limits. And I don't think anyone can argue that NAD products are underpowered!
As you can probably tell, I'm a NAD fan - the 2-channel stuff at least.
I'll agree that their AVRs have tended to be feature poor in the past. Plus, they are wayyyy overpriced. But, their philosophy has always been SQ first. So, they don't try to pull the wool over anybody's eyes as to video performance. So, for somebody whose main priority is multi-channel sound, they couldn't go wrong.
If I have a gripe about NAD, it's the pricing of their products. I'm glad I bought my C-372 when I did. The replacement (C-375) costs about 75% more! Unacceptable! They used to be reasonably priced, but that's gone now. As much as I like their stuff, I couldn't justify the new asking prices.
If they've ever had any quality-control problems (not in my experience!), that could be a criticism. Plus, they are now too expensive. But puh-leeasse,
don't give me any nonsense about SQ!
