At one time when I was into the subwoofer thing I was using a LP1 modified by a local technician who upgraded all the capacitors and resistors. The improvement was clearly audible with less veiling and more transparity across the frequency spectrum. I sold the unit to a friend who used it for awhile until a speaker change put it in the closet where it still resides to this day.
So, if you're thinking of mod-ing it, by all means, do so. The results were worth the cost for me.
