Sorry to clarify turn off as in from the back of unit or just putting it standby from the front of the unit...We suggest turn-off when not using it.

If that is a well informed answer then it's very disappointing, as my DX7 pro never had to be turned off, it will put itself to sleep as soon as my PC goes to sleep or turned off.
It runs warm not hot. Headphone amp section is always on as it shares supply with DAC section.My EX5 is still warm even hours after switched off (by remote control). Especially the case area above the internal power supply (top back left corner) is warmer (I mean almost-hot-worm), but the entire case is warm nonetheless.
The only way the case cools down and reaches ambient temperature is to turn off the unit from the I - 0 switch/button next to the IEC C14 type power connector on the back of the unit !
Is this a normal behavior for DACs or DAC+HP Amp combos with relatively small enclosures and internal power supplies ?
@JohnYang1997, @SHENZHENAUDIO: please clarify this situation/issue regarding the overheating of EX5 (in my opinion), because I am afraid to leave home and leave the unit even in standby for fear that something bad might happen.
Yes.@JohnYang1997: thank you for the clarifications.
But when in standby, it is normal for the unit to be still warm ?
Seems like that (same with other recent Topping models) standby just turns off the display but all the circuitry is left largely powered on. So not really standby mode by any modern means. Personally I would much more prefer the standby mode to be actually standby mode as in power usage less then 0.5W and "sacrifice" the auto on/off capability if need be.@JohnYang1997: thank you for the clarifications.

Can I use a switch activated power strip to turn off and on?!? I use something like this Foot Powerswitch (for years) with my Fiio E09K/E17 setup - and also turn the power off on my 2.1 Adam nearfield studion monitors (A5X + Sub7) - never had an issueWe suggest turn-off when not using it.
Unit comes out of standby once it detects a valid signal on the inputs. Unit goes into standby when there is no valid signal on inputs for about 30 seconds i think on top of my head.Then what the point of Auto-On/Auto-Off, what actually happens when this feature is enabled?

Actually should put standby between brackets as the unit is never really put into standby.
I dunno, I didn't come up with it.Hmm i see, so why even go into "standby" at all if the unit is still running and is recommended to be powered off anyways.
To interject some data into this discussion, I used an IR thermometer to measure the top housing temperature on my EX5. After sitting in "standby" mode for more than 24 hours, the top of the unit registered about 92 deg F (33 C). I then began playing back music via the headphone output. Volume was set to high gain, 70% output driving my Sennheiser HD650s. After 45 minutes, the temperature had moved less than one degree! I then raised the output level to 90% (resulting in an uncomfortably-high listening volume), and the temperature remained the same. Somewhat surprisingly, then, I found no difference in operating temperature between standby and headphone operation. This has convinced me that placing the unit in standby is a waste of time, and from now on I won't worry about it.

Sorry, I don't have a power meter. However, I also thought the temp is probably a pretty good proxy.Interesting - are you able to measure the power usage in similar conditions?
Edit: probably not necessary to measure power as your temperature measurement is pretty conclusive, I was wondering if power measurement will show a tiny decrease in standby due to the screen being off? Agree it's pretty pointless.

It's been on standby all night, no signal going to it though: ambient temperature 79F, EX5 temperature on top was 85.2F, power usage at 1.5W. I turned it on (with remote power button) and it jumped to 5.2W (again no signal sent to it), and after 20 min of sitting there being on with no signal, it went up to 90.1F. After sitting there for 1.2 hrs on with no signal, 5.3W, it went up to 96.4F with 77F ambient temperature. It seems to rest warm even when not playing anything.
If you are playing from a Mac, it is an Apple thing. Apple Music on the Mac does not automatically change the output sampling rate based on what is playing; you have to change that manually using the Audio MIDI Setup tool. Major pain in the butt. Oddly, on iOS devices, automatic switching IS done. John Darko gives a pretty good overview of this topic:I got my EX5 today. Doesn't seem to display 192khz when Apple Music says it is playing 192khz. Not sure if that is an Apple thing.
