Salas is the electrostatic shield of the R-Core introducing the noise when connected to chassis earth.
This laptop doesn't like earthed mains noises it seems. I don't remember earthing reconfiguration talks for mini computers and streamers in this thread. They just worked without a glitch. Then again not all small toroids used these days have static shields and drain wires. You have a big R-Core one of the most potent makes.
Haven't researched that aspect because its a general supply and who knows the interaction in each different application system but as it doesn't have many parts the transformer and the reservoir capacitors are the main quality target items.
Improved a lot the sound quality using two 10.000uF, used the Mundorf for C4.
Also noted as a volum increase, before music far from me & now near me....

Salas doesn't work well, time to time the volume level decrease a moment and inmediately turns normal level. I suspected of laptop power consumption when using DSD upsampling so tried lower DSD rates with same problem, so I listened original DSD files without DSD upsampling with the same issue, also the L-Adapter lose dynamic & sounds difused without focus.
Monitor voltage at the end of output cables. If it does not drop significantly during high current demand there is not something better you can do with the supply itself. Else, you can use thicker cables with tighter termination and maybe higher Vout adjustment within the max spec of the laptop's DC input allowed. Basically as much as its SMPS brick measured unloaded should be surely tolerable.
I use the same cable supplied with the SMPS.
Vout SMPS: loaded (not playing music) 19.28V unloaded 19.34V

Vout SMPS loaded upsampling pcm 16/44 to DSD256 min. 19.24V max. 19.29
Vout L-Adapter unloaded 18.98V
I set the L-Adapter unloaded to 19.34Vout, I will listen & come back.

Hello Salas.
I built 3rd l-adapter for WiFi router 19v 1.7A.
Transformer is 120va 24v(It get 22v in my country for 100v wall tap)
Sound is amazing as always.
I appreciate for this build.
I like l-adapter so much.
Its easy build,simple,less parts,wider voltage choice and larger current,powerful and good bass sound comes.
I worry about a Q2 heatsink temperature get around 40-45℃.
I worry because it's on 24 hours.
Is it good way to mount on alumi chaiss bottom? It's 3mm but no fin.
I also built 24v ultrabib for acp+
It's amazing too but I prefer l-adapter.

Very nice again. Congratulations. Full aluminum case for sink is more capable than a little on-board sink I believe.
