If there is anyone still reading this thread, a point to make on Dean's product is that he uses common parts where possible so repair is possible down he road, unlike some who design with rare parts ensuring a boat anchor in the future. My PSE Studio IV has the IEC upgrade, internal AQ midnight cable, and Cardas Rhodium posts. The sound is unbeatable for the price. I also hope he rethinks starting his business again. The hi-end can always use quality products. Service may be another matter. I recently had a friend measure the Studio SL preamp on his bench and we were both shocked to see that it was ruler flat from 5hz to 100khz...within 0.5db, and the distortion was 0.004%! These were real numbers, not printed numbers which don't have to be accurate. Finding a preamp with 0.00 numbers is not very common. Many have distortion of 0.1% and this is not even at rated power, causing smeared images, muted dynamics etc. Making 100khz is important because in order to reproduce perfect square waves at 20khz, you need the preamp to be flat at 100khz. Good job Dean. Stay around....
