The Outlaw is an amazing piece. I have one and also purchased one for my brother's birthday after I owned mine for two years. I have listened to the Brio-R at a dealer and it is a very capable performer. However, the build quality and features cannot match the RR2150. The Outlaw is so well designed and has so many features that you might need that it really is a Swiss army knife - perfectly executed. Add to that, the dac, phono, tone controls, processor loop, manual crossover, tuner all are so well designed. I did direct comparison to HArman Kardon 435 and I preferred the Outlaw.
I have traveled down the path of the perfect all-in-one which has lead me to the Arcam AVR600 - which costs $3000. However, I still have my RR2150 and will never sell it. Too useful - too awesome.
