I was told (by the internet;). That the NAD being a class D amp, that it was of better quality and more expensive price(upon further research I discovered as you pointed out, that it is rated only 45W at 8ohms instead of the 70W advertised, which it seems like is at 4ohms).
I found a Cambridge Audio AXR100 at a very good price, it seems that it puts out 100W at 8ohms. Am I correct in assuming that will dramatically increase my ability to get a high volume with less distortion because I won’t be pushing the amp as I would my NAD c338?) thanks in advance for your input.
