Rowland JRDG 501 and Wilson Audio

RGS92, what model of WaTT Puppies did you listen to? G.

Are there Spectron Musician owners that are using Wilson speakers?

I found the 201s had no soundstage or depth on the Sophias. Quite stale/sterile sounding and suffering in dynamics.

I had Nuforces Ref 9s on my Sophias that sounded phenomenal. As I said earlier, ymmv.

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.
