I wouldn't say my system is similar, but I did recently move from an older Rotel DPL preamp with outboard decoder to the 1050. At the time I was using an excellent Tandberg stereo amp for my mains and a Rotel multichannel amp for the center and rears.

Today I am using the 1050 as my preamp and to drive the center and rears while my Tandberg still drives the mains.

Very pleased with the ease of use and better sound. Hope this helps.
