Mark Levinson 23.5

Guys, thanks for your input. I actually turned off the amp last night. After a couple hours after this post I felt it's running way too hot, not warm for comfort. Years back, I burned in cables leaving the amp on most of the day and I don't remember anything like this. They must have done something. My dealer is closed today but I will definitely be calling them tomorrow morning.

Good luck, keep us posted in your 23.5.

Yes Woobie, will do. Its going back in Saturday. I just hope they didn't screw it up on me. I'll be really pissed because this is an awesome piece, age and all. We'll see!

Update, received my ML 23.5 back after I brought it back in for service because I felt it was running too hot, much normal than it use to. After another 3 weeks I received it back. The repair shop checked and adjusted the bias. They claim to have load tested it and basically abused the amp in their sound room. They said after this extensive use, the temp only got up to 128f*. I brought it home and set it up in my system. I'm using new speaker and balanced interconnects that I am auditioning. This should eliminate any issues with cables causing possible heat generation. I swapped left and right speakers as well in the event possibly one lost its impedance value. After having it on for a few hours and playing music at a low volume, the amp warmed up. I then sat down to listen for a few. After about 20 minutes of playing the amp a bit harder, the temp shot up to 132f on the right side and 122f on the left.  I refer to a bit hareder as my normal listening level. No way pushing this amp near 50 if not less. I'm not a blow your eardrums out listener. Ive had this amp for 15 wonderful and it never use to run this hot. And the fact the right side runs 10* hotter concerns me as well. I'm not sure what I should do. I don't know it they can do anything else with it. I love this amp and its sound. Although running hot, it sounds phenomenal. Should I push to have them look at it again or pay the freight to send it out to the east coast for repair or trade it for something different? My dealer mentioned trading up as an option to a Bryston 4B or Ayre Acoustics amp. Not sure which amp this may be but it retails for $9k. I'm not in that position right not, so that option sucks. Any thoughts?

You didn't mention how you measured the temperature but assuming a temperature gun, its possible to have 10 degrees F margin for error, depending on how you hold/point the gun or the specific point of measurement. Just a possibility.
