I have a NAD 272 power amp linked to a NAD T752 A/V amp and have had ** end of problems. Purchased in 2005, 6 months after, the right speaker (Paradigms studio 60) channel would just fade away periodically, and then come back with a thump. Noone (NAD audio repair shop) could initially find any fault but when I powered just thru the 752, there was ** channel drop out.
The 272 was supposedly fixed, (altho NAD still say they could find ** fault)it happened twice again, and last fixed in November 2006. Last week, 6th March 2008, the same problem arose with the left channel. I have taken the CD player out of the equation, problem still existed, DVD player out of the equation, problem still there, the FM tuner in the 752, problem still there. Take the 272 out and put all speakers thru the 752, everything runs fine.
The speakers have been stripped down to ensure ** crossover wires are touching. I run a NAD CD, an OPPO DVD, a Project turntable thru a NAD preamp.
I'm bside myself as is the local NAD agent.
