My Cambridge 840C and 840A (CD player and amplifier) allow for balanced connection. Am i likely to get much improvement in sound if i use this rather than RCA inputs - The handbook suggests I will! Am considering buying Nordost Blue Heaven interconnect with XLR connectors for balanced connection in place of my current Audioquest Copperhead interconnect (based purely on reviews etc since almost impossible to listen to these things here in portugal). Using MA RS6 speakers. After reading the thread on Gotham interconnect I'm getting worried that cables are overrated!!! Help please.
