Pre-amp for Rowland Model 102

http://www.audioenz.co.nz/2007/rowland_capri-102.shtml

I'm using Power Factor correcting conditioner Furman Elite 20 PFi with Rowland 102. It does not affect dynamics but makes everything cleaner. The strange thing is that bass became cleaner - more even and musical. Very good non-sacrificial over/under voltage protection is another benefit. I don't have to worry about leaving it ON 24/7. 102 is plugged into high current outlets while Benchmark DAC1, I use as pre, is plugged into lower current preamp dedicated outlets.

Guido, I don't have Capri. Furman made it cleaner. They claim large peak current available (large capacitor behind large inductor) but it did not improve dynamics (other than removing bass resonances). Furman made big difference on my previous digital (DLP) TV, making colors more clean and saturated. I know it doesn't sound plausible in digital domain but removing jitter can do it. One thing that made huge difference was speaker cable (Acoustic Zen Satori) that enhanced lower midrange (Cello, male voice chestiness etc.) where 102 seemed to be a little thin. In addition it has this "silky" quality (but I'm rather new to high end cables).

Guido, PC1 converts 110VAC to 175VDC and 240VAC to 385VDC according to Jeff Rowland info:

Most of the gear won't work with DC voltage at all because of transformer.
