So we've got silver wire in our tonearms. We've got 99.999% pure silver wire in our cables that run from the arm base to our SUT's or phonostages.
Those who have not sampled the delights of low output MC carts and Step Up Transformers need not read further (unless you are curious / want to spend loads of dosh on said MC carts and SUT's:) ).
Today I've been messing with cables from my SUT's (Lundahl 1:13 jobbies that are point to point silver wired)...
I been using my favourite OFC copper RCA cables but thought I'd try 99.999% pure silver twisted / shielded as the RCA's from SUT to Phonostage.
Ok as scientific as I get: A SUT increases the voltage output from the cartridge seen by the phonostage (in my case 1:13). I also have 1:26 available but do not need it with my current phonostage and preamp arrangement.
It does this according to the laws of physics. W = V x A (that's power = Volts x amps). There's no gain stage involved so to increase the voltage the amperage is decreased proportionately to maintain the equation. So the actual power (minus some miniscule losses in the SUT) is the same.
So, if silver is great for the diddy voltage levels and power levels in arms and tonearm cables, why not use it from the SUT to the phonostage as well?
That's what I've done this evening. I made a 99.999% pure silver interconnect using 0.3mm silver and a braided / foil shielding to run from my SUT to phonostage.
No hum problems to be heard. The jury is out as I've not listened enough yet - I'll let you know what I think after more listening but what do you other MC / SUT guys do? Are you already using pure silver RCA's / interconnects?
