Paradigm is alot of speaker for the buck.. I own Studio100's v2, StudioCC, StudioADP's, Studio20's and the Servo15w/x30 controler They are all in the rosenut veneer except the Servo and center I guess your already guess im using the AVR5800. I will tell you right now you will not find a better speaker unless you spend a heck of alot one thing though.. If you like the finish just as much as the sound "DONT BUY THEM" Although the rosenut is very nice and THICK they are still very much a plain box! And yes I would spend the extra to go referance but only if you have a very good receiver or pre/power amp combo
