250 dr

Hi i originally posted about my 250 dr going off the boil and losing some bass ,having read all your posts i thought i would try some of the advice that had been shared i powered down the amp for a couple of hours  switched on and every thing is back ,i don"t know how or why but my system is singing again .Have just spoken to Naim told them all that had been going on they said that had"nt come across this issue before,  but i might have a heat problem and if it doe"s it again to send it back to them  ,all i know is that at the moment everything is good and hoping it stays that way.....
