I have the Xpression III now with a phono tube box II and the speedbox I using an Ortofon turbo MC-3 cartridge. Would it be worth to upgrade to just the RP3 with the same cart and no additional components like the TTPSU? I really like the adjustable isolation cones of the Xpression III. Is there a direct screw in replacement to the feet on the RP3?
TIA
