Jeff Rowland 501s and PC1s

I installed the PC1s with my 2 Yr. old 501s and am very happy with the improvement. Sound stage is wider, taller and deeper. Image is more pronounced with increased detail.

As for value, $3200 for the PC1s on top of $6700 for the 501s is alot of money. A lot of very good amps at this price piont.

For me, Rowland equipment has a very natural, uncolored sound that I have found compatable with all my other equipment over many years.

System:
Esoteric X0-1 Limited
JRDG Concerto Pre
JRDG 501s
JRDG PC-1s
B&W 802Ds
Cardas Golden Reference, all cords, cables and ICs
ASC Tube Traps
Room Dem. 13'x 15' x 9'Hi

Hi Dave,

well you have to recognize that with 5 power cords instead of 1 you have some more margin to play with. The combination also allows to change the preamp ... for ex. go the Criterion ;-)

I would only agree with him if your speakers are very distant from the preamp.
I find big diferences beetween power cords, interconect and speaker cables also when they are short. You can really define a way you like and go quite far on it. I feel even that sometimes that cables can make more difference than preamp, amp or Cd player.
Just my opinion

I understand what you're saying, but my approach is to eliminate PCs and ICs. I think of them as added to potential distortion rather than being an opportunity to "tune" the system. In keeping with JRDG design philosophy, "keep signal paths short and simple."

If you're likely to move up to the Criterion and 312, then it makes sense to me, but not so that you can use more cables. ;-)

Hi Guido,

I have finally received today the original JRG cables to use between PC1 and 501. I am afraid theses are not the same ones as in the US, as they are not "pig tails".
Anyway it is obvious that my modified NBS Monitor 2 are quite better:
Stage imaging more deep and better outlined musicians, sound with more power and bass.

Clavil, are you using 1 or 2 PC1 devices? The 501 monos require 2 of them. You should allow for about 300 hours of break in on the PC1s before they stabilize. Guido

I use 2 PC1, they are on the way to the 300 hours or almost above? I don't know
