The chances that changing your preamp-to-amp interconnect cable will make a significant difference are increased if:
1)The output impedance of the preamp is high, which is most often the case if it is a tube-based preamp.
2)The preamp-to-amp connection is unbalanced (rca).
3)Cable length is long.
4)Capacitance per unit length of the existing cable is high.
5)Ground loop-related hum or buzz is present, which goes away when the safety ground pin on the power amp's power plug is temporarily isolated with a cheater plug.
6)RFI or EMI (radio frequency interference or electro-magnetic interference) is a problem.
None of that has any particular relation to the fact that rca connections are used for the turntable to phono stage connection.
Also, IMO, do not expect a high degree of correlation between cable performance in a given system and cable price. What matters more is how the design parameters of the particular cable match up with the particular system, which does not have a great deal of predictability.
