Jeff Rowland 625 amp ... & 725


Some months ago I was already positively impressed when I had the opportunity to compare the 312 (class D) to the new 625 (class AB) in the same system ...

today my dealer told me that Jeff Rowland has sent him a new "platine" (board in English?) to install into the 625 and that it is sounding even better

this upgrade seems to be free !

I am very looking forward to hear it and wondering how will be sounding the 725

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.
Guido, any news on the plans for a Criterion replacement? I thought that was pretty quick for JRDG to delete a statement model that fast. Also any news on JRDG phono preamp? With the resurgence of analog, I would think one might be in their future plans.
Hi Phil, I have no info on Phonostage projects at JRDG one way or another.

I know that a Criterion follow-on project is underway, but I do not know the exact release timeline. I suspect that the Criterion follow-on my utilize PSU for power supply. Guido
Oopsie Tab10s.... Sure thing.... should have been "eight-ball" not egg-ball. Afraid that English is not my mother tongue, as just transpired... On the other hand, I contend that playing pool with a fresh egg as ball number 8 should add an unexpected splattering fun factor to the old game *snickers! G.
