Hi
I have the same set up. I'm curious as to the significance of keeping them apart. Using Wave Storm Ref BNCs.

Actually due to space limitations i have the gear stacked (scaler on bottom):
Qutest
Teddy Pardo PSU
M Scaler

Doing anything wrong? Thanks.
Quite a few of us here advocate hiding the M Scaler.

When it is set to automatic input and automatic video (if you have a mixed music/TV setup) then M Scaler requires no user interaction. These two automatic capabilities are genius, I thank Rob Watts every time I sit down to listen or watch a Blu-ray or some telly.

So with no interaction, M Scaler can be hidden. Put on the floor or hidden in a cupboard a few feet from the DAC. I do the latter.

I don't know what a Teddy Pardo PSU is like, but I'm guessing there's a toroidal transformer inside it. Toroidal transformers are nasty nasty nasty things (non-toroidal even worse) as their magnetic fields ruin analogue music circuits that are nearby. In the Naim world this is a key reason for having a brawn rack, full of power supplies, and a brain rack (pre-amp, DAC) so that the transformers in the power supplies are kept away from the analogue music circuits.

It should cost you nothing to try spreading your gear around. Free upgrades are the best :)

If the Qutest is the smallest of all three of these boxes (is it smaller than Teddy Pardo?), maybe it's easier to hide Qutest away since there's no need to play with its controls in normal usage.

Apparently they work well (DC4) with the DAVE.

Does moving them apart help? Yes (5 m). How far apart do you need to go to really tell: I do not know. BNC cables (at least standard ones) limit you to 2m ....
The 3m optical cables of the Opto-DX make separating them easy (And the optical cables are flexible/easy to manage).

Fixed your post for you. 🤣😜👍
And Sean Jacobs (make the dc4) is just the nicest most helpful person, as are most people in this hobby I suppose.

The poster wasn’t saying that a linear power supply powering equipment was a bad thing, but that stacking equipment directly on top of them is what was bad. Actually since they mention a stack of power supplies to power the equipment it appears they are advocating them, just not in direct physical contact with the components they are powering. But you knew this right? I just couldn’t see your tongue in cheek. Now I’m feeling a bit silly even mentioning it, but just in case…

yeah, thats what I’m getting, not hot but warm and thats because it’s been on for 36+ hours, as I’m afraid to turn it off :)
I keep my HMS on constantly as well. I do turn off my Dave however. It gets warmer than the HMS.

I turn DAVE off but leave MScaler on. MScaler gets hot when operating, but is cool when in auto stby.
This is how I‘m using my Dave/HMS combo. I was wondering if Dave owners leave their units on or not.

My setup, Nuc / source > MScaler > TT2.

I just did a IR temp scan of my setup minus my nuc.

The MScaler is 38.3 oC, and the TT2 is 35oC. So they are not crazy hot but thats just measurements on the outside of the case. Chances are high that its a good bit higher on the inside, but something similar to intels TDP will save things from cooking up.
