Purchased a NAD T761 receiver a few months back. Decision was based on strong musicality and excellent movie reproduction. Recently noticed that DTS movie soundtracks were lacking bottom end compared to DD version. After confirming a 10 dB reduction in the LFE (with a SPL meter), I had it shipped off to NAD for service (still under warranty). They did not notice any problem however a 10 dB SPL reduction should be perceived as being half as loud....I guess I am a descriminating listener. I recently read a review of the Sherwood Newcastle R-956R by Stuart Robinson of HCC which had the same problem. Can this problem be corrected by the manufacturer? Help!
