I have been living with the B&K ref30 for the past 6-7 months and I think it is great. I use it with the B&K 7270 amp and Soliliquy speakers. My ref30 came with the older ver 2.05 software/hardware and the company immediately sent the a new ver 2.08 replacement (n/c). Once everything is set up correctly it is a breeze to use. Even my wife (a 100% technophobe)can use it. One complaint is that the input connectors on the unit are extremely snug making interconnections a bit of a "challenge".
I am not familiar with the Sunfire so I can not offer you a comparison between the two.
Hope you find my input useful. Enjoy, Ken
