I've been looking for a good pair of bookshelf speakers for my office... and wanted to get thoughts on the RTI A3's. They would not be part of a surround sound set up... and would be used for music only. My budget is low... I don't want to spend more than $400. They would be paired w/ a Technics 100w receiver... with a wide range of music. Would these be a good option? Any thoughts or feedback is appreciated. Thanks.
