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

Guido,

My dealer gave me both PC 1 for home demo with modified NBS Monitor II power cables, I only got the original JRDG cables yesterday ... he was right!

Hi Clavil, just trying to understand. . . you were using NBS power cables instead of JRDG 'pigtails' between PC1s and 501s, and you experienced that the modified NBS power cords yielded a more desirable sound for the 501s. If my description is correct, I expected your results. . . the JRDG 'pigtails' are just stock wires, and as such they are unlikely to be at the level of any high end aftermarket power cords. Guido

Hi Guido,

I got the 501s with the Capri together (power cables AET EVO Hin from the first day),
than I had one PC1 on the Capri (power cable between these two NBS Monitor II from the first day),
later I got a second PC1 and I put them on the 501 with two Monitor II,
I had never seen the JRDG original powercables for the PC1 until I wrote here, I asked for them to hear the difference with the Monitor II ... that said the european JRDG cable is not a Pigtail ...

I hope now it's a more clear ... sorry for my english

Clavil, the JRDG cord that connects PC1 with an amp is a 45cm long power cord. It has a male 15A IEC at one end to connect to an amp, and an IEC 320 connector at the other end to connect to the PC1. Such a very short cord is often referred to colloquially as a 'pigtail', even though it is straight and not coiled like the real tail of a cochon. Is the PC1-to-amp cable supplied to you any different? Guido

Guido,
yes I was thinking at the Pigtail, a cable in shape of a "queue de cochon" ...
now I have it in front of me, yes it's 45 cm long, there are a lot of things written on it:

(UL) SJT E159216 VW-1 75° 3X18AWG CSA SJT LL112007-1 VW-1 60° 3X18AWG H05VV-F 3G1.OMM2 -VDE- Kema-Keur öVE CEBEG IEMMEQU

the modified NBS Monitor II are definitively better than this.

I wonder why perfectionnists like J.R. are selling their products and not caring too much about cables? ... OK better for us, so we can do our experimentations and have fun ;-) but I really don't understand from their perspective ...
