Hello, I haven't posted in some time. I guess I didn't have much to contribute until now. I just purchased a new pair of Studio 590's and I have to say I am very impressed. I had an opportunity to audition a pair that belonged to a friend of a friend and that convinced me to try them. I am running them in a strictly two channel rig powered by a Yamaha A-S801 integrated amp. It's 100 watts per channel and sports a killer ESS DAC with CD and Pure Direct capabilities. I haven't got them to rattle the walls yet but the sound is punchy, accurate without a hint of being too bright. They really shine with vocals and acoustic guitar.
Another major reason I decided to buy them is they were designed by Greg Timbers, how could I go wrong! They do have an unconventional look but my wife actually likes them which is a major bonus. I highly recommended them.
