Thank you to all for your excellent input. I have decided after all this to keep the current wiring as I have idea at all which way to go. I noticed a world of difference in the 300 rewiring, but from my reading, it seems Rega has in fact improved the wiring on the 700, dramatically. I am totally useless with a soldering bun so anything I do will have to be done with my wallet, which is growing thinner. Right now I will enjoy the new EAR 834P phono stage and Dynavector 17D3 with the wonderful Groovetracer mods. The superb sounding Adcom 555, pushing my JBL LE15A's and the MAC 275 powering the Janzens esl's through my Mac C220. The wiring will have to wait, but I appreciate all the input for future reference.
P.S., I just purchased the Adcom from another Audiogon member and it is sweet for those beautiful Vintage JBL's
