Rowland Concerto integrated vs Rowland Capri & 102

I got my info directly from Jeff Rowland and from the friendly crowd at Soundings HiFi in Denver.

Clip from a Soundbytes Newsletter on CES (Winter/2008? - sounds like already happened in the review so maybe last Winter):

JEFF ROWLAND: Several new goodies here; first up, the new Continuum integrated amplifier. The new design will be available in two versions, one with 250 watts per channel (at 8 Ohms), the other pushing 500 watts a side (both double into 4 Ohms). Built into the larger amp will be Jeff’s new PC-1 line conditioner (see below). Both models ought to be fantastic - we’re impatiently awaiting their arrival. Prices will be $7995 and $9995 respectively.
Long awaited and finally a reality, Rowland’s new upscale preamplifier, the Criterion, was debuted. The two chassis stunner offers four balanced and two single ended inputs. Outputs include both balanced and RCA connections. The Criterion features battery power with an internal, self charging NiMh pack. Rowland gear is known for its total absence of background noise, but the battery power on the Criterion pushes the signal to noise ratio into oblivion with a quoted rating of >100dB. Channel separation is an astonishing >100dB. Estimated price is $18k with an anticipated release in February.
Looking to compete in a new area, Jeff introduced the PC-1 line conditioner, designed exclusively for use with Rowland products (Capri, Continuum Integrated, Model 102, Model 201 and Model 501). What sets this unit apart from the competition (in an admittedly crowed field) is power factor correction (PFC).
PFC explained in brief: In an ideal world, an audio component would present a purely resistive load where the current and voltage are in synch. In practice, audio gear presents a more complex load where the voltage and current don’t follow one another and are therefore considered reactive (inductive or capacitive). The more complex the load, the worse the device’s power factor will be. In the most simple terms, PFC is a way to correct for differences (bring into synch) the voltage and current waveforms. Jeff tells me that the sonic benefit of PFC emulates the performance advantages of battery power.
Frankly the details of this design philosophy are a bit over my head, so I won’t attempt a complete explanation, leaving the more technically minded among you to research on your own. I will however, be happy to report what my ears tell me when our unit arrives. PFC-1 $1200

I have asked JRDG about compatibility of the PC1 with the Concerto integrated amp. While out of the box the Concerto is not compatible with the PC1 because it is preset for 110V operation, it can be switched to 220V operations by changing the position of 2 internal jumpers and replacing 1 fuse. After this change the Concerto will accept the PC1, but can no longer be fed 110V AC until the voltage change is reversed. According to Jeff, Concerto will benefit from PC1. I suggest that anyone interested in matching the Concerto and the PC1 consult JRDG directly at (719) 473-1181 before attempting the input voltage modification. G.

Guido, I'm hanging on to hear the new integrated replacement for the Concerto. It's like a Capri plus 501s in one box, then I could add the PC1 in front of it.

Our man Rod will get all that together for audition in the near future me thinks.

BTW, are you still enjoying that speaker set? Rod seemed very pleased with how it turned out.

Dave, me man. . . you's talkin' 'bout the Continuum 500, which has PFC circuit built right into it. PC1's needed only for li'le brother Continuum 250. Not sure if Continuum integrated have the circuit of the Capri inside, or a derivative design. Rod at Soundings might receive a unit in a couple of weeks. In the meantime, my Mahlers after the Master Set sound tremendous.
