Great thread. I loved the DQ-10s for many years; reconed the woofers and finally sold them on the net. After 2-year search, bought the Waveform Mach 13s after driving to the middle of Ontario and hearing them at John Otvos's house. (Got the next-to-last pair, before John switched to the easier-to-manufacture Mach 17s.) Still have the Waveforms and am not looking to upgrade. An outstanding speaker, and not equaled by anything below $15K today. (I also own Watt/Puppies, but only for home theater. Intolerable for stereo.)
