Hello
This is my first post here so please move it if its against policy

I willing to buy very fast audio SMPS (silent, with very low noise, with silent switch, protection etc...).
I am about ready circuit (best) or DIY kit (PCB + controllers+transformers, I can assemble it as well - but testing might be a problem)
Parameters
2000VA +/-75V or 80V (equivalent of 1500W PSU transformer i- I assume some backup capability will be surplus in case of overheating?)
Requirements:
I am interested only in detail tested circuits with well reputation perhaps there are available some for group buy?
2/4/8 Ohm load will be needed (4 as default)
This is supply for Accuphase 7100 Clone so ideally without any fans please (in worse scenario kind of emergency ones only)

Any proposals? Directions? I really want to get rid of classic transformer...

I googled a lot but still not happy with results:
I can see on connexelectronic.com something like "SMPS2000RxE" and at least two circuits on aliexpress/ebay called: "G-014 1500W" or "2000W High efficiency LLC soft switch Amplifier audio power supply".

thank you for the support

I had a 1200W version as attached, but its out of production at the moment as I am very busy developing other projects.

I dont recommend the chines option at all, the connex is your best choice for now as I also dont like its components quality either.

That amplifier need serious power supply as I can see.


Let me know if you need further help

Thank you for the hint.
If even connex in not an option then what ? I am quite desperate...
