Ediscreation have a similar device with their fibrebox

Ifi Audio also has one.
Which is listed under Silent power division.
Both look good, unfortunately no option to replace the optical cable.
Where as with the larger devices it is always an option to try something from Cisco, Finsair or another optical cable that best suits the chain.
Probably all has its pros and cons I guess.

Thinking of purchasing a used (latest gen) Apple TV and modding it to remove the internal switching power supply and converting it over to an external LPS. Theyāre cheap and given the improvements Iāve seen implementing audio hobby improvements into my TV, I think this may be a worthwhile thing to explore.
I saw improvements in the display when I put in a hand me down power conditioner. I saw improvements when I plugged a Shunyata NR cable into the TV, I saw improvements when I bought a second Cisco Meraki to mod and used that as the Ethernet switch for the TV space.
The nice thing about the TV is that cheap seems to go a long wayā¦ maybe because thereās more noise there to begin with? Dunno. Anyways, Iāll fiddle around with this over the next couple of months and report back. Itās also a good way to repurpose the 8 disparate LPS Iāve got sitting around all over the place.

So how are you āextractingā audio from your AppleTV?
Iāve had pretty poor luck with standard spdif extractors, even with better cables and power supplies. I tried using various ddc and ended up fighting audio lag/sync issues. Iāve been tempted to try something more audiophile like this (with the 2ch output option):
But Iāve been generally pretty happy with airplay streaming to a Rendu endpoint. Itās not true bit perfect (it resamples to 44.1), but itās the best sound Iāve gotten from it so far.
Iām vary curious if youāve found a solution you like.

I mean, grab an old blu ray player and some physical disks and that will be the biggest improvement. Better yet set up a server and burn to there.
The cheap route. Iām getting the HDMI from the Apple TV and then optical out from the TV into the Pontus II
This may be a better topic from an AV thread. Do we even have an AV thread?

Okay after some reading and hunting around for the right unit, I bought a 2nd Gen Apple TV 4K, the A2169 model which is a different animal than anything before it and anything after it. Shows some of appleās corporate thinking and then be bean counters winning out, they always win out in the end.
Anyway, will document this as itās a pretty basic little project but Iām going to follow two rules, itās got to be on the cheap but itās got to have the same foundational principal Iāve followed in my 2-CH. which is address every component in the system.

Interesting so I thought Iād share for anyone thatās gotten a bit over the top with their network optimazation. Itās also a relatively ācheapā tweak for an audiofoolās budget.
The thought process is thus.
We know the PC is filthy dirty noisy thing that needs to be kept as far removed from your audio gear as much as possible. 
howeverā¦ we all still sit in front of our PC connected via an Ethernet cable to the same switch that our expensive audio trinkets are also attached to! WTF?
In my example, itās a Roon server, a Sonore opticalModule and a Lumin A1 streamer DAC.
So, Iām trying to address the obvious polluter in the switch and what I did to adress that is buy a cheap Ethernet to SFP converter. You know, the ones you trip over everywhere on Amazon for $30 to $40 bucks. This one came as a kit with two boxes and two transceivers but Iām only using one; Thatās because my Meraki switch had a open SFP slot after I moved to connecting my Lumin U2 in my 2-CH setup via the Sonore opticalModule.
So in summary, moving my PC from an Ethernet cable (which you can see disconnected at this time in the pic) over to a short fiber run from the SFP converter to the Meraki switch.
I had a decent ifi power supply so Iām using that to power up the SFP converter. I threw the PS into the mix because I had it, but itās not as critical here as itās on the isolated side. The reason Iām using that though is to not introduce a dirty wall wart into the AC power as Iām connecting it to the AC conditioner all the other gear is connected to.
Iāve got to say that I did this purely on a whim based on nothing other than theoretical best practice, but Iām glad I did it. The PC was clearly shitting noise into the Meraki switch. The streamer is improved, ot crazy but certainly noticeable enough to be certain about it.
PS: donāt judge the dust and sloppy wires, this was still an in progress pic and wasnāt finished with setting everything up. lol

Following along with what @dB_Cooper just posted here is a good video by Hans who is one of the more competent folks presenting info on YT IMO.

Can you provide assistance to what and from where I can purchase the paste and a proper sized heatsink please? Unit gets sooo hot, i need to dissipate the heat best possible.
I want to go from this:
