Nice studio system. I am familiar with the Auditor Elipsas as I was using them in my 2ch/Theater room some time ago as side and rears in a 7.1 setup. They are actually great little speakers. I even tried them on pedestals for fun and they impressed me.
I also have used the Peachtree a few times and bought one for my son's system some years back. So a total of three different experiences with the Peachtree...
I would suggest one thing, look for another integrated, the mini Elipsas are capable of impressing more than the Peachtree can do for them.
