As a former Soundstage(and Stage 1)owner,I can tell you that you are going to have a tough time equaling the excellent 2 channel performance of the Soundstage at anywhere near it's price.I have not been able to equal or exceed that level of quality since I sold mine three years ago.
My Soundstage was sold to provide upconversion to component video.Then I moved on to HDMI.
My current Integra DHC 9.9 is an all around outstanding performer.It does a nice job with 2 channel in the Direct mode,but nowhere near as good as the Soundstage.
Since I have sold the Soundstage,I have been through the Stage 1,Denon 4306 Receiver,Pioneer Elite 59 AVi receiver,Onkyo TX-NR905 Receiver and now the Integra Pre- Pro.Only the Elite 59 AVi came close.
I do keep a seperate 2 channel reference system for those rare moments when I have time for critical listening.
