I just had the cover on for the whole day and thought to actually measure;

Temperature around the 40.000uF caps is 32 degrees (C); the further hottest spot I can find on any of the other (small) caps is 42 degrees (this is in between the second pair of heat sinks and those large caps). So, quite ok.
Btw, ambient (room) temperature is 22 degrees.

Hi - I thought I would update my recent comments about z4 after a few days listening. I find 4 much clearer and precise than 3 and overall I can hear much more detail. Vocals are really much clearer. However the sound has a hardness to it that means I listen at a lower volume. I do not know if there is some inherent high frequency distortion or some such derived from the software or if extra detail is "pushing" my system into misbehaviour. Anyway I cannot go back to three but I it would be great to get rid of that hardness to the sound. I have tried changing settings but it does not get rid of the hard character of 4. Bit its OK at lower volume and the other improvements make it worthwhile.

All the best

It will play with KS engine 4 but only to Juli@ wave out...not SPDIF 

Ah, and who is going to take care of the music ? All I know is I have a couple of "ABBA-like" syntesizers. Yes, there are really three of them there.

big party in Spring at your “small home” in Oene.  You are responsible for the tent, the  meals and the “fluids” are by us.

All the "metal" has gone, z4 is MUCH better than z3. 

you just hear each instrument and every instrument is made of metal .

Less beer Gerard, less beer. Beer is not for all Gerard's !

Oh, I thought I had told sufficiently enough about this ? (Release Notes and ToolTip).

Something strange. I am still in adaptive mode for now. I find that I prefer straight contiguous mode over mixed contiguous as music seems to flow better, more lively and better clarity. However, suddenly I kept getting error message about memory allocation error 03, lower SFS, reboot or change mode. Currently, I am down to SFS 10 with straight contiguous mode. However, when I lower SFS, music also becomes leaner, seems to emphasize treble more. I like the slightly darker, richer sound in mixed contiguous mode with SFS 100 but like the pacing and music flow/detail of straight contiguous. I wonder what I would have to do to run bigger SFS in straight contiguous mode?

ok i´ve tested a music with 8 minutes and it takes about 8 to 10 seconds to play. then a played a mp3 with 70 minutes...
and about 50 seconds... apear the logo thak says the bit rate (in this case - 160 mp3) but.... after that a still don´t ear nothing...
is very strange...  first i though that was the demo version... but than i realised not.
than i tried a mp3 file with 32 minutes and it played. than i tried another with 37 minutes and does n´t played...
so i think i can´t play music with more than 30 minutes....
my config  is a asus n61 laptop>spdf optical>dac> amplified monitores

Less than 40C.

Gerard,

All is about the recharging capabilities and the speed at which that goes. When this drops, the capacitor just doesn't have enough "capacity" within the time frame needed.

I'll do it a bit by heart now and the figures will be wrongish, but it is to get the idea :

A capacitor often is rated for 60 degrees Celcius. This is a fairly normal temperature within electronic devices.
At 60 degrees the best caps (which are just in the NOS1) will last 10,000 hours. This seems much, but for a device of which it is advised to keep it On always (and without that advice we'd do that anyway, right ?) - it is not. Not at all, because it would be just over one year only. Now think something like when the (for the caps) ambient temperature is 20 degrees C lower, they will last 1 million hours.

Notice that a more normal (low quality cap) may be rated for 1000 hours only (60 C).
