Yes, do the wood body on your 103R. There is some pretty compelling info at the vinyl asylum (just do a search there using aurum beta and audio technica) suggesting the Aurum Beta S is nothing more than a slightly improved AT 95.
My guess is that a $69 AT 120E would equal or better the Aurum Beta S.
