My system is as follows: VPI Classic 1 Sony SCD-777ES SACD Player Whest PS.30R Phono Stage Musical Fidelity A5CR Pre Amp 2xMusical Fidelity A3CR Power Amps bi-wired (All amps upgraded by John Sampson) ProAc D15 Speakers Pioneer SC-LX75 Receiver Grover Huffman Phono Interconnect Nordost Red Dawn Speaker Cable Nordost SPM Interconnect (SACD-Pre Amp) Nordost Red Dawn Interconnect (Between pre amp and Power Amps) Nordost Blue Heaven (Receiver - Pre Amp) I have contemplated changing the Nordost cables for some time but now know that the system is picking up hum from the unshielded Nordost Interconnects, especially between the receiver and the preamp. I have confirmed this using borrowed cables. I wish now to replace the nordost cables, I want shielded hum-free cables which are as neutral and revealing as possible. I'd like to spend under USD200 per interconnect, the less the better. I'm currently looking at the following but all suggestions and advice are welcome.
