Audio Advisor has the Boston VRM50 bookshelf speakers on clearance for $399 a pair. They have excellent reviews on this site. Normal cost is $700/pair. Are they worth checking out compared to say B&W 601S3 which also has good reviews here? Has anybody compared the 2? I'm also considering the NHT Classic 2 but have not found any reviews on it yet. But does anybody have experience comparing the Bostons to these models?
