Rowland Concerto integrated vs Rowland Capri & 102

MrBill, info on PFC has not yet been posted on jeffrowland.com. The little I know is from conversations with Jeff R. and Rod Thomson of Soundings HiFi. I hope that eventually some official info will be posted to the site. G.

Well PFC or no PFC, I went for a lightly used Rowland Capri. It just didn't make sense to lose money by selling the existing 102 amp.

Now then, while I await shipment of the Capri, can anyone enlighten me as to what sonic improvements I might enjoy with it? I'm not expecting a huge difference, but I really haven't auditioned the Capri. I just know I like the sound of the102, even as it was being preamped by an Arcam Solo (odd combo that it was).

It's interesting that there are audiophile glossaries on the web, but not much in the way of basic primers for budding enthusiasts. I Googled for ages looking for some simple pre-amp FAQs, or answers to basic questions like, what should a good pre-amp do to improve your sound? What differences should you be able to hear in a $1500 power amp vs. a $200 Best Buy closeout receiver? The best I could do was browse myriad discussion threads and look for sage-sounding advice.

Some of these audio manufacturers could probably sell a lot more gear if they spelled out, in not quite so technical, and in not such an assuming way, exactly why it is one should want their products over an old Sony dorm stereo.

RTNY, what I have heard on the Capri is an exceptional top to bottom extension with extremely good harmonic development and low level detail. It sounds very musically engaging.

In slightly less technical terms, YAY!

Thanks Guido.

Rkny, I have learned a little more about the Power Factor Correction device called PFC. Rather than feeding a 110V 60Hz AC signal, the PFC uses a microprocessor controlled circuit containing both inductors and capacitors to feed a PC1-compatible amplifier or preamplifier a 384V steady DC current. The current is then stepped down to approx 30v in the power supply of the amplifying device, and in turn is expected to facilitate a much smoother charging rate of capacitors in the circuit. In turns, smoothly charged capacitors are expected to contribute to reduce distortions and maximize reproduction of low level detail, etc. . . .
