KN, in the Socratic tradition, your wisdom lies in not having knowledge of even one thing going forth, only to emerge with truth. I like to think so, anyway. Having little electronic knowledge, my DIY efforts have centered on the areas of room acoustics, building cables and the isolation of gear. These are product categories open for development by anyone, and it's just plain fun to achieve improvements on your own, without succumbing to the purple prose reminiscent of the Old West's traveling medicine show, where no claim is too fantastic to believe. It also helps to acquire finer new and used gear, even at reasonable cost--then the real DIY fun comes through, as you well know. Do you have some links to pics of your isolation/system?
