Any others experienced this -
I've had a 250 for a number of years and it's handled several rocking parties with no issues.
However I recently had the amp modded to DR. On Saturday night it went into thermal shut down.
Are the DR's causing the amp to run hotter?
TIA

I have no 250, but I've been reading many times on this forum the opposite. DR seems to be more stable.
A first thing to do would be to check cables. Maybe just re-setup the stuff. It seems that it can make a difference.

Unless you were really pushing it, I would check for the usual suspects of load stability (length of speaker NACA5 cable, running parallel to mains etc)... failing that I would get it checked...

James, I would second Simon's post above. Check the usual things - also has anything changed, particularly with regard to where the NAP250 is situated? The case is the heatsink and unlike the NAP300 there's no additional heatsinking and fan cooling. Beyond that, have a word with Naim and see if they feel it needs to be checked out.

Thanks chaps.
I should have mentioned that no changes to the system pre/post mod.
In the meantime, I have delivered the amp to my dealer. It's being checked out...

My 250 (Non DR) would shut out regularly after an hour or so of "enthusiastic" listening levels from the SL2's with 2 * 5m NACA5.
Probable causes were that it was too enclosed on the bottom shelf of my Isoblue and possibly was pretending to be a NAP300 at those levels.
