Over heating NAP250DR

The other thing I would add about a 500 is that it is very revealing and the source has to be up to it.

It really comes to life with a Chord Dave as a source - and can expose weaknesses of inferior sources.

Yess!!! We finally have a Chord DAC on a power-amp thread  My day is now complete.

You know that you are nothing without a bloody Chord DAC. 

We were discussing the 250 not the 500, it's only slightly more relevant than the dave.

And it wasn't I who mentioned it!

No, I was just responding to that Allante question - looks like he got a massive dose of FOMO - fear of missing out - and the lack of funds seems to occupying and dominating his peace of mind.

Maybe his kit isn't set up properly either or he got electrical issues, when Naim kit doesn't come on song, one can start to (based on all the upgrade excitement on the forum) - wonder maybe the next level up will give me that Naim sound.

It's nonsense - even the Nait 5i and Unitiqute got the Naim sound, and just needs a little care to make it sing.

I could live with a UQ if I had to, and it would be a very fine sounding hi-fi system, given matching speakers.

Anyway back to the 250 shut down, again, it's a powerful amp, but a little care is needed, 3.5 M of NACA 5 minimum, and sensible use, it's not a whole home device....

And I shall call thee 'lesion' - for I am dyslexic!

Or even 'foot' for thou art leg end.

Touché! 

OP: have you checked the power cable is in phase? I had a similar problem with an UnitiLite getting really hot to the point it skipped disks and powered off by it self. Changed the phase and solved the problem!

any suggestions of changes to mains wiring (unless its a fig-8 power plug and hence can be inserted either way around) is going to get a stern frown from Richard

Hopefully you will audition one Adam soon, and see what it is all about

Happy here with my humble NDS + 555PSDR

I sent mine back. I am nothing again 

you sold your Naim too, and moved to Devialet.

The class D amp of Devialet destroyed the transient accuracy that Rob Watts worked 30 years of his life to create, no wonder you didn't hear it.

Suggest to try again with a Naim

You got strange taste, but it's a free world.

No i listened to the Mojo through my Shure IEM's - It was very good but not as good as my Sony DAP so i returned it. 

fair enough.

Or unless you are based in contintental Europe where getting the phase right or wrong is quite possible.  A phase test induction pen is a good investment there.

Indeed.

One more 'complication' also arises in continental Europe: despite a seemingly simple agreement, mains cable manufacturers actually do get their phases mixed up. Generally it should be in the right-hand side of the component-end plug (plug viewed so that pin-holes are visible).

Naim's  and Linn's mains cable's are actually consistently wired differently - their phase is in the left hole (at least the ones I've come across over the years).

Many reputable cable manufacturers get it consistently wrong. The same cables from the same manufacturers can be wired differently.Thanks to standard Shucko plugs, cables can be plugged in differently. 
A phase test induction screwdriver is vital here.

The cables can sometimes vary too - Musicline used to mark the phase on the plug of the mains leads with a white blob.  That way you could ensure that all were the same way round. They may well still do that...
