I own one of these and have auditioned the Lightspeed. I think it is slightly better, but they are more alike than different. In my opinion it is an excellent sounding piece.

Anyone tried this?

I use a Lightspeed in a second system and as a back-up to my Doshi. While not perfect, it's one of the all time great bargains in hi-end. This LDR adds input switching and a remote. I know George argues that including multiple inputs will degrade the sound, but just wondering if anyone has ever heard this new product.
