well, put it this way, you need to compare the tradeoff between the Bolder M80's which, imo, are pretty much the best reasonably priced IC's out there, or DIY and for cheaper maybe getting a tiny bit better.
but to answer your question, I would definitely say YES! It is worth doing, the silver cables I made turned out wonderfully but they will reveal problems you may not know you had elsewhere if you do. Catch 22 of resolution.
