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.

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 ...
Yes Clavil, that is the 'pigtail', minus the 'recessive gene' that would make it coil like a tirebouchon. If manufacturers supplied high end cords with their component products, they would have to charge significantly higher prices while giving you power cords that may not be necessarily of your taste. On the other hand, it would be good if they readily published specs of slightly unusual cords they use, like on PC1, so audiofools like us can experiment easily with upgrades. Now that I have heard about your experience with NBS on PC1, I am intrigued. . . I might try a Furutech wire, as I like those a lot on Rowland gear. G.
