Rowland 625

I just called the factory. To start with, at CES, JRDG appears to have 2 suites, probably in the Venetian:

35-204
30-231

The current price of M625 is $13,500; current price of Corus is $12,200.

Yes I heard Corus, but not in my system. I have not determined yet audible differences from the Criterion that I own.

There is no ICE nor other Class D technology in M625. Apparently the device is packed full of A/B circuitry. Device weighs 54Lbs or so. Finally some specs have been posted. You will find them in the M625 section of the JRDG knowledge base at:

Thanks Kawika and Guido!

I was able to find one EU dealer that had a price for Corus. It is extremely much higher than in the US. Almost double.
It is more than 5000 usd, more than C-500, in euro.
This is sick!
This was the case, and is still with Krell, Wilson Audio and Wadia also.
There are no way the tariff and tax cause a justifiable mean for that pricing scheme. European brands in US, are not near. Actually it's quite often almost same price.

The Corus+625 would be nice to try out.
Though, i can't understand the 625 didn't come out as a more heavy amp as it is class A/B with ordinary toroid transformers (i guess)?
Even so, it would probably outshine my loudspeakers!

I see the cause of your surprise.... M625 does not use heavy toroidal transformers in power supply. Power supply is high speed switch mode, preceeded by a power factor correction-based rectifier, hence the contained weight.

Guido, what do u recommend in terms of a power cord for Rowland amps. I know you had some success with Furutech power cords. I'm using Shunyata Anaconda Helix via an adaptor as my previous amps were 13A, not too sure if this compromises the sound but I'll probably use it for my DAC or transport later when I get a 20A replacement power cord.

Dtanclim, as you know I do not have direct experience with M625 in my own system.... My amp is still the Rowland M312. Furutech and Shunyata CX series worked for me remarkably well on M312 in a manner that I personally deem to be synergistic with JRDG sound. G.
