NAD T763

I'm just bringing this up because I want to know if others have similar experiences. I got the T763 as a AVR decades ago, when it was first new. I actually bought the previous model which bonked out and NAD replaced it with the brand new model. I've sort of relegated this amp to an upstairs bedroom where we don't use it much and also when I shift speakers around, it gets the worse speakers. The thing is that whatever I pair with it sounds fantastic. I'm only running three speakers with this amp and it turns speakers I've given up on into wonderful sounding speakers including more bass than I thought possible. I used to mostly purchase NAD stuff but nothing has lasted or shone like this monster.
