It shouldn't run hot. I never turn mine off and it doesn't go above 35C, idle or not. Do you have enough ventilation or another source of heat nearby? I doubt it dissipates more than 2-3W on idle.
My setup, btw, i exactly like yours

Topping PA5 II Stereo Amplifier Review

I have muchO experience dealing with electronic circuitry operating at thermal runaway from 85C up to and including a calibrated certified operation @ 177C at the top level of qualified stuff.
35C is peanuts and is very OK.

Never said anything about whether it would damage the electronics just that someone might consider 35C "hot" when touching it.
Comparatively my Purifi amps run much cooler albeit with much better passive cooling than that tiny PA5 box.
I hope you don't own any class D amps running at 177C...
No the 177C stuff is special high heat application tools for downhole metering. Holes like hundreds to thousands of feet deep in the Earth strata.
In a room at 24-25C anything using electricity will be warmer than that. 35C is body temperature and very comfortable to touch. The amp normally sits at 32-33C, but I can't guarantee the room is 25C. In a warm day it can reach 35C. It's not so important and I wouldn't worry about anything below 40C.
On the topic of hot, a while ago we were destruction testing 200W power resistors in a lab. These things just refused to die. 30 min glowing red at 175C surface temperature and still fine. Took us hours to finally melt one.
Aaah, we were designing power inverters for solar panel farms and it was part of many tests required for certification. They were supposed to "fail safe" and we had to prove it by destroying them in supposedly faulty condition.
I don't remember the details, it was 6-7 years ago, but I remember the setup, the smell, the crazy temperature, and the long time they lasted. Nobody expected them to be that reliable

It's less than your normal body temperature...
ahhh ok so I'm not alone. It has been a habit for me not to forget to switch it off or its gonna warm my room lol
its stacked with my dac at the corner of the desk near the window with a fan pretty much constantly blowing across the desk out the window so I want to say there is ventilation. I live at the equator with no air conditioning in my room so the temp is pretty much 29C at best at night to 33C all day.
its definitely warmer than my hands when i touch the amp.
That seems normal, taking into account your room temperature.

Hmm looks like I'll have to eat crow on this one then.
I'll see if I can find my thermocouple and measure my wife's PA5 the next time she leaves it in overnight. It's definitely quite warm to the touch.

New to the PA5 II Plus team.
It came on Monday and sounds nicely.
The sound is balanced, neutral, without coloring. The better the source is, the better the output will be.
Playing FLACs 16/44.1 to 24/96-192 from Sony UBP-X800M2 through my SMSL D-6S.
No sibilance, no boominess. Stereo image is nice.
My old cheap bookself speakers (Crystal audio TX-B1) are neutral sounding, 89db/W sensitive, 6.5'' glass fibre woofer + 1'' silk dome and I'd say that they couple nicely with PA5 II plus.
I' m a bit confused, about what cables to buy in order to connect balanced the D-6s to PA5 II plus.
XLR to mono 6.3 TRS microphone cables?

TRS is the "stereo" jack
TS is the "mono" jack

Sorry, but I can't find this Dac anywhere...
Do you mean smsl d6-s ?
Smsl su-6 (no S) is not balanced
