Hello, I just picked up a used rgi60 on Audiogon and I am extremely happy with it. Great depth, wide soundstage, very tube sounding without being muffled. System set up rgi60, cambridge audio d500se cd player, wharfedale music 1.6's (i know these need to be replaced and soon/but sounds good) I listened to musical fidelity and creek in comparison and the rgi60 sounded much more open and fluid.
