I think it’s the form’s text editor.
In my system i almost always hear differences from power cables. I can also test against each other easily because I have mono blocks. I will just start with some cheap ceramic fuses of Ali. Aucharm.

I have the mono blocks, so no need. But have you considered upgrading the fuses at the power inlets? Should be an easy upgrade with potentially a lot of improvement.

Cleaned the HTML so it is readable:

My first modification was installing a second PSU into my Hypex Nilai DIY500 Stereo amp to double the power output into 4 ohms. I disassembled the amp, drilled 14 new PSU mounting holes and five large holes to fit some metal Temu air vents. The additional PSU is supplied with two amplifier connection cables (not required), a power input cable and a 12-pin auxiliaries cable (J5).

I soldered the power input cable to daisy chain it with the original power input cable.

I also soldered five wires on the 12-pin auxiliaries cable to the original 12-pin cable. This required carefully removing some of the insulation from the original cable, soldering the ends of the new cable onto the original, and then insulating with electrical tape. The five wires I connected were:

• Pin 2: Ground
• Pin 7: Pushbutton+
• Pin 8: Pushbutton-
• Pin 9: Trigger+/-
• Pin 10: Trigger+/-

The end result sounds slightly better than with a single PSU, in my opinion. The extra headroom seems to have given the bass more weight behind it and added to the overall clarity at louder volume. Nilai with two PSUs. Case underside.

My second modification was adding a gain switch (on-off-on 6-pin) to the rear panel. It seems to work and can be easily reversed if it has any negative effect on the sound.

Just ordered a clone Accuphase C-2860 plus. Not really a clone since Accuphase doesn’t have a 2860, but it seems to be a modified version of the C-2850. It’s a class a pre-amp en is to serve a set of Hypex Nilai Mono blocks.

Maar ik ben nu open baffle opties aan het onderzoeken…..

Op het moment de Revival Audio Atalante 4

Ik heb laatst eens de power supply van de Experiabox aan een buizenbuffertje gehangen. Want beide 12v en voldoende ampère. Dat klonk me toch een partij slecht.  Gewoon vervangen door zo’n Mean Well van minder 2 tientjes, die zijn al veel beter. ( LRS-50-12 ) Je moet er wel even zelf snoertjes aan knutselen.
