Rowland JRDG 501 and Wilson Audio

Most ICe amps will sound painful in combination with the Focal titanium tweeter Wilson uses. Perhaps the 201/501 would be less bad with Rowland's new outboard power supplies, but I would still think you want an analog amp with Wilsons (PS - What made you decide to buy Wilsons?).

For what it's worth, the only times I heard the
Watt Puppies sound really nice and smooth was with Levinson 33Hs and
Transparent cable at the old Soundex in Pennslyvania.
I think the preamp was Levinson also.
Otherwise they sound scratchy to me.

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.
