RCA to XLR adapter vs buy a balanced cable


Hi, I have a phono stage with XLR or RCA output. Till now I was connecting it by RCA IC. Having changed the preamplifier to a balanced one I have now two options:
1) buy good RCA to XLR adaptor (Cardas?) to enter in the preamp (please note my power amp is unbalanced, so output from pre will be by RCA
2) Using same amount of money (approx 160 Eur) for a full balanced cable(In this way, phono stage output will be balanced and pre input too)

It might sound a stupid question, but I have limited budget for my toys and need to maximazi benefits
Thanxs if you would give attention to this
Cheers

don't go crazy. no need for adapters as they would make no sense unless your amp is balanced as well.
Thanxs but still what you advise? I have phono preamp out XLR or RCA choice . Line stage is no choice input only balanced, while output can be RCA optional to XLR.
Shall I get a balanced interconnect between phono and line stage, or just use a normal high quality RCA with adapters?
It might be debatable if XLR sounds better than RCA (requires additional circuitry to make it balanced), but having choice between RCA+adapter or XLR I would choose XLR for it's superior noise rejection (assuming the same cost).
XLR between phono and preamp OK, adapter for poweramp isn't necessary, because amp isn't balanced and you can keep RCA.
