Ryanmh1: "I've been told that one of his "modified" units measured around 10dB channel separation." Although 4yanx has composed a very reasonable response to your opinion, I would like to emphasize that you do not state any real evidence other than heresay for your views. How do you know that Mr. Scott did not specifically design the unit for someone with only 10dB of separation? If a customer lives in a region w/poor reception, he/she may be seeking modifications that are appropriate for distal reception rather than audiophile sound. I had Don modify a unit to my specific requirements, and the end result was ideal (he also guaranteed the work with no strings attached).
Just my opinion.
