I want to reverse engineer it a little more than my last attempt seen here

Topping PA5 Review (Amplifier)

how loud will pa5 drive the hifiman susvara, the actual sensitivity is 79 db/ unknown 1 vrms or not Here is the Susvara's sensitivity and efficiency as claimed by Hifiman and measured by 3rd parties: The PA5 can output at least 26Vrms into 60Ω. That's 92dB + 20*log10(26) = 120.3dB SPL , which...

and make a replacement D-01 module thats open source


Why dont i do this with the one i depotted allready?
because its my only one and it works since i repaired it,
if this doesnt go to plan, i may have scrapped a perfectly good PA5 rather than a broken one.

Are you still open to this? Having a bad time with a support service, I might be able to provide one (not guaranteed, yet). There are a few questions I have, though.

1. If you're open to this, are you fine with a (hopefully) Brand new Pa5? It would be shipped to me first, where I would test it and briefly listen, before re-packing and sending it your way.
2. I'm in the US. Would that mean that you're willing to pay 150EUR+ Shipping on top at your expense, or 150EUR for the unit, and I pay to ship?

Yes, im still looking for one.
id rather tear down a broken than a new one if i had the choice but in the end it doesnt matter which condition its in.

My budget is pretty tight, in addition to the pa5, i gotta order pcbs.. parts.. more pcbs because i screwed up, more parts.
50 bucks of my 150 offer comes from another asr member that wants to support me.


My offer is with shipping included (paid by you / the sender.) not counting import duties... thats another story if it even gets trough (they get pretty mad if its missing a CE logo, even if its a sticker you could peel off easily, thats not allowed)
both are expensive, it would make no sense.

thanks for your offer but i gotta pass and wait for someone from within EU.
