I currently own EOS HDX, and have owned just about every model of GMA speaker over the past 10 or so years. I run them with a 2A3 SET and couldn't be happier with the sound. I would describe them as being detailed and revealing. Once you have heard time coherent speakers, I doubt that you will go back. As an musician, I feel that they remain true to the recording and the intent of the musicians and producers. Thus I have not had the desire to roll speakers although I have heard many competing designs and brands.
As important as the sound though is the fact that Roy is a great guy who is really passionate about producing a great product. There are few companies who provide personal service AND upgrade existing products rather than forcing you to buy their new latest and greatest. Green Mountain is one, Ayre is another one (oddly enough, both are in Colorado). At any rate, if you are considering Green Mountain, you should definitely give them a listen, they are a bargain at the price.
