Psxr2 - what is the difference

Postby Silence » Fri Aug 31, 2018 8:29 am

I recently bought a psxr2 second hand - its an upgraded psxr. I couldnt hear any difference from my old psxr on my amplifier 8vs2 . So I opened up both units and was quite surprised to find the old psxr pcb dated 03/01 inside the unit - the only difference I could find was the addition on some magnets on the DC lines and the wires running from the transformer- is that really the only difference . Does anyone have a picture of the inside / pcb of an original psx-r2 ?

Old psxr from 1991:

Upgraded psxr2 - magnet around wires from transformer and around wires to the output

First thing I’d do is contact Cyrus with the serial number and make sure it was upgraded.
And verify it is a genuine one not a scam.
Assuming you have made sure it’s genuine I can’t help further. Again, why not ask them by email?

If you click this link then it should show the internals of a PSXR2 :

Magnify it for further detail.

I'd be surprised than an old PCB is used if it has been modified by Cyrus.

Just found this from the Cyrus archives :

It would be interesting to see what they actually do. I am sure I read a thread some time ago that said they did little more than add ferrites to key wiring internally on some models, but can't remember where. "
