Hi, I guess I fit into an unusual group. I design and build all my gear (going on 10 years now), but also make them for the diy / consumer communities. I'm half owner of a modest electronics company specializing in Diy kits. I have been told my kits are equal and sometimes better than anything like it. I agree, but then I am prejudiced.
I am just like you. I am happier when I buy all my sound devices right from the Speakers to the last. I am trying to become better at building better devices, but I know that it is going to become a bit better for me with time. I don't feel those vibes when I spend dollars buying any tool that I make use of.
