I currently have the rc-52 II with matching surrounds and bookshelf's up front. I would like to test some different speakers to see if I am missing anything. I live in an area that makes it difficult to test a lot of speakers. I would like to compare these to a dome tweeter based system. I am thinking about buying a pair of Def Tech 1000 Bookshelf to see if there is a reason to switch my system. Worst case scenario I could sell them for a small loss on craigslist. So I am asking for suggestions on if I should give the Def Tech a shot or compare using another pair. I am happy with the klipsch but like you all I am always looking. Thanks for any suggestions.
