as the wire size changes, smaller, the resistance increases as a factor of length,
Thus a long run of 12 gauge will NOT be able to deliver the full voltage at the terminus of the line - so 120VAC at the breaker end of the line could, depending upon length, drop to 105 VAC, then the supply into the transformer will be low, and as transforms are ratio based, the output from the transformer with low input will be affected. Which will affect the balance of the equipment- sagging B+, means lower bias for gain devices, timing circuits based on capacitor charging may not trip - if they do not get to a high enough voltage, some SS regulators will have reduced or no output
So in short the equipment will actually suffer as opposed to benefit from the dedicated line.
