First off, I have a 20 year old NAD reciever that still sounds fantastic but has recently started to have dead spots in the sound knobs, rotary pan style. I noticed I can play with the loudness button and that will get sound back sometimes. The power isn't going off just the sound as if it was completely muted. This is still a very nice sounding reciever even with only 75 watts per channel. The headroom on the amp more than compensates for the lower wattage for me and drives my 20 year old AR's great when it isn't cutting out. It used to drive maggies and the AR's fairly well at one time. Ok, old equipment needs some maintenance sometimes, but I cannot locate a good repair shop anywhere in the Tulsa, Oklahoma area for this. I am kind of emotionally attatched to it, my first real sound system, so I would like to repair it and keep it in my bedroom. Anyone know a quality repair shop for NAD in the southwest? Preferably one that warranties it's work.
Second off, I was curious about an old issue I was familiar with that seems to not be discussed much anymore. Namely headroom in amps. I know I am behind due to having my old equipment for so long now. But that little NAD with 75 watts per channel drove my 2 old maggies and 2 old AR's better than some 150 watt amps I hooked up. It has monster reserves of headroom and this made a tremendous difference. Especially in very dynamic music, like rock, the 1812 overture or numerous "Live" recordings for example. Maybe all amps have great headroom now. I don't know myself but I am curious. I don't seem to see this rating on literature anymore. And since this forum seems to be very knowledgable on current systems as well as old maybe you all can educate me some.
Your opinions are appreciated.
Take care all
