Standby temperature?

Audio Components DACs
1

Today I need to move the newly upgraded DSD, and found the case is quite warm thru it is power off.

My usual practice is keeping the switch on the back on, and keep it standby. Just power on and off by the PS logo or remote control.

What would be the proper standby temperature of the machine - if measure on the case?

Comment and advice welcome.

It should be OK as when you power off PWD/DS it will only disable it’s display and mute the output, but all internals are still running. This is feature from PSA to keep your DAC always “warmed up” to play music at it’s best SQ :)

Mine is just pleasantly warm to the touch when left in standby.

My cats seem to think it’s pleasantly warm as well. :)

Leave it on. On, on, on. It really takes weeks to get this puppy broken in. … er cat …

Temperature measurements with an Infrared thermometer.

Non heat producing objects near equipment is 79 degrees.
Perfect Wave Transport is 84 degrees.
Direct Stream is 92 degrees.

Thank you for all your answers. I may found the reason.
During my upgrade to the DSD, I have not use the original fuse and "upgraded" to a Hifi Tuning fuse. The only version of HiFi Tuning available in HK is "XXXX Blow".
Before I get your answers, and I already change back to the original fuse that comes with the upgrade kit and I am happy to tell you that the temperture was back to normal now.
However, with the HiFi Tuning supreme fuse, I found the sound quality really feels better.
Now here comes with my new question, did anyone ever upgrade the fuse? Which brand did you recommend? 4_gif

I am very surprised the fuse used impacts operating temperature. This should not be the case.

It is good to hear you found the source of the problem and have it fixed. :)

Actualy the only way a fuse can change the operating temp is when the fuse is blown.

Normaly a fuse has a very low impedance. Both fuses suit be very near to each other.

The temp change must be caused by an other cause in my opinion.

11

This makes sense to me as well. Yet, we have the problem solved by changing a fuse. Of course, somethings else may have inadvertently changed in the process. What cold this be?

Could a defective fuse, exhibiting an abnormal resistance for example, cause the rest of the unit to run warm?

12

When a fuse is defective but not entirely blown or has a loose contact it could heat up the fuse holder, but with this small fuses it won’t take a minute to melt the fuse.

It must be another cause.

When I feel with my hand on the bottom of the DS it is warm mostly, but sometimes it’s just cool. I think a very small breeze at home keeps the unit cool.

13

By the way resistance is the right word. I could not find it with my poor english so I used impedance.confused

14

You are probably correct.

And your English is excellent. Besides, most native speakers do not understand the difference between resistance and impedance. :)

15

Yes, but…

We are Borg. You will be assimilated. Impedance is futile.

Just does not sound right and I suspect that even the average moron would agree. :smiley:

We’re mostly above average morons, I like to think.

Oké, but what do others think

Before adding the Bridge, I never noticed a difference in standby or operating temperature from anything else in my system. But now with the Bridge installed, my PWD MK-I runs noticeably warmer to the touch. Of course, being sandwiched in a Bright Star Audio Isolation combo doesn’t help heat dissipation. And neither does draping sheets over the equipment rack to keep dust and pet hair at bay between listening sessions!

As others already mentioned, keep the back panel power switch ON for best sound at moment’s notice. The PWD was designed without ventilation slots, so you should be okay as long as you keep it out of direct sunlight and away from heat sources.
