Offfpphh. That is ridiculously short! I have a Systemdek that current has about 1.5m run and it can barely plug into the amp. The turntable sits on the top shelf of a Alphason glass stand that has a total of 5 shelves, the amp sits on the bottom and it can just about reach!
I wouldn't change a Systemdek for an RP1 and I don't think I'd change it for an RP3 either to be honest. Would you not be better spending on cartridge and/or arm upgrades for your current turntable?
