Hi Brent - Thanks for your post - the GMA's are quite unique, I am planning on sticking with them. In fact, I just got a phone call from Roy, the designer. He called because he noticed my post about finishing my Stereomour. Since I have had the EOS HD, he has redesigned and improved the crossovers, upgrading resistors and changing some values. He is sending me a pair for my speakers. Talk about service, Roy is a great guy and really a pleasure to work with.
So here is the philosophical piece:
I went through a period of swapping out speakers and amps every time I wasn't satisfied. Not only was it expensive and time consuming, it also never got the results I wanted since no single piece of gear is perfect, it is all about trade offs. The reason I turned to DIY was so that I could tweak and change things, try different interconnects without paying for marketing hype, build power cords, and now roll tubes. etc.
I am very pleased to be a part of the BH community because that is what this is about. Start with a solid, reasonable design, build it and then tweak it for your individual tastes (and budget). This is awesome. Although I am starting to eye those Paramounts, damn.
