Dan,
Sounds similar to Kimber PBJ in concept, design, and results. Which is good because, that's what I'm using throughout my system. If you start a new thread with the title 'free interconnect trial' you'll probably get a lot of positive responses... including one from me. That is.. if you want a PBJ comparison which is the best I can offer. The lengths sound right for most applications.
Thanks,
Carl
PS, as to the original post, yes, no, maybe.... and it depends. It's part of 'tweaking' which is something that requires experimentation for a desired result. If you don't hear an improvement, it wasn't worth it... hey... that should be my signature!
