I've seen the selection at Best Buy. They seem to carry only the most affordable models. I'm a big fan of the Kg and Reference Series. The newer speakers don't have near the sound, engineering or build quality of their classics.
A few years ago I purchased their unique looking GMX-D5.1 multi-media surround set. Upon first listen I was surprised by the level of noise with no input. I liked the speakers, so immediately dumped the control pod and sub/amp and drove them with a 6ch NAD I had lying around.
I later went to a Klipsch Pilgrimage at their Engineering facility in Indianapolis. I asked one of the reps about the excessive noise level of the GMX. I had done some research and found the noise was a common complaint in the forums. I was told it was a design decision. That the consumer wanted more output, so they increased the gain and increased noise was the result.
I'm sure they could have redesigned the module, but more likely just changed a few components to increase the output. Bad decision in my opinion. I see the same types of compromises in their more current speaker series. They are, in my opinion, also starting to price themselves out of the market. They're not the value they used to be. I love my classic Klipsch'
