Rowland JRDG 501 and Wilson Audio

Yeap, that's the problem of the 201s. . . they definitely lack 'lung' capacity for relatively large speakers like the Sophias or my Mahlers. I am not surprised that the NuForces did well on your Sophias. . . I have used the Nuforce Ref 9V2SE on my own Vienna Mahlers, which are probably more difficult to drive than Sophias, and Nuforce monos control them with aplomb. On a different system I have also heard the JRDG 501s being plenty confy on the Mahler's. . . conversely the 201s can't drive the big Vienna Mahlers to any satisfactory degree.

Those were WP6's way back in 1999. By the way,
I owned them with a Pass X350 and they sounded tizzy.

Raquel:
what do you mean with "painful". are the focal titanium tweteer with the Rowlands to sharp in the high frequencies? is this also the case with ceramic or diamond tweeters?
I have a large listening room and I need a fullrange system. So I decided to go with Wilson Audio.
Why spend customers thousands of dollars to treat their listening room, when in the least case only a Wilson plays music?

Hi RGS, I remember not being fond of WP6s because of their tizziness. . . but have heard the newest WP8s driven by both Bat and CJ electronics and found them to sound very graceful instead. Have not heard them yet driven by any switching amplification, so I can't venture to guess how they would sound with JRDG 501s, even if PC1 PFC units were added. G.

Soundoc:

The Focal titanium tweeter Wilson uses has a resonance that is audible in the presence region, between 4,000 to 8,000 Hz. There has been a lot written about the problem here and at the Asylum. In any event, go listen for yourself.
