Temperature test...

[Matthew]

This has been an interesting discussion. I've always believed (conventional wisdom) that we wanted our components to 'warm up' and would sound better after being turned on for some period of time (keeping tubes out of the discussion). So are saying that this may not be the case?

I cannot say I've heard sound differences with temperature increase/decreases but also have not previously looked for them either. This summer with a D200 in a moderately confined component rack my temps could have fried an egg! Silly me I did not look for the readings. At one point I actually turned a fan onto it (which cooled it waaaaay down so as barely to even be warm.

Last night I checked my temps, now with a D400 and both units completely open and ambient temperature at 21°C I had these results:

Temp at start up from fully off
A - D - S
26-26-28 master
32-31-35 slave

Temp after 30 mins -20.5 dB
34-32-34 master
36-34-38 slave

After 60 mins 
38-36-38 master
38-35-40 slave

After 90 mins
39-37-39 master
38-36-40 slave


I'm going to keep an ear out for SQ changes for a while.

Manoet, you amaze with your efforts!!!!
