Ayre Codex

How hot was the Codex get?   Is the Codex okay to be placed in a cabinet with the front door closed and the back open?

It does get hot.  For your application, I would only ask Ayre.

I agree - you should ask Ayre for the real answer. My guess is that it'll be ok since there’s a way for the heat to escape. I’d be concerned if it were going into a rack with all sides closed off and no fan to draw out the hot air.

Someone told me the Ayre Codex DAC get very hot when used with a headphone but just warm when used only as a DAC.   Is this true?  

As was suggested above, I plan on calling Ayre today and will post their response.  Thanks.

Ayre reports "the heat from the Codex is perfectly normal.  The heat comes from the Diamond output stage and pure analog power supply which are used in the Codex".  

Ayre says “this creates more heat, but it is a big part of the reason it sounds so good”.   There are no problems storing the Codex in my cabinet and I plan on listening to an Ayre Codex shortly.
