Jeff Rowland 625 amp ... & 725

Claude, the external PSU device cannot be applied to power amplifiers at all.... It was designed for low current applications only. It is currently compatible with Corus and Aeris. In the future, it will be compatible with the Criterion follow-on preamplifier.

M725 is powered by an internal high speed DC SMPS fed by a 1500W PFC unit, also internal to the M725 chassis.

And just in case anyone asked... No, PSU is absolutely NOT compatible with the now withdrawn Criterion or Capri any other preamplifier... If you ever managed to connect the two by some jerry-rigging, you will likely end up with cute little fireworks, followed by even cuter blue smoke, charming smell of singed circuits, and.... not so charming knashing of teeth (your own teeth, that is).

Hi Guido, was the RRP for the PSU confirmed? Also any indication from Jeff Rowland whether a Corus + PSU will match Criterion? Thanks Mark

Marc, as far as I know, the PSU unit shown in Vegas was an advanced prototype, not a full production unit... PSU has not been released. I have not heard of any price yet.

What I have heard about PSU is that it is a power supply based on supercapacitors instead of NiMH batteries. At least in theory, it should be capable of delivering quite a bit of authority, because supercaps are capable of very quick power surges, while NiMH batteries are not. But, until I hear the effect of PSU on a device myself, I will have no idea of what it really does for living in general, nor whether it lets Corus surpass Criterion in particular. G.
