Mike,You are likely right that 5 x'forms will sound more colored than 5 resistors. However, there is a basic technical difference between resistor and tranformer based volume control devices.
The output impedance of a typical resistive pot is high, in the range of a few kohm to a hundred kohm depending on total value and volume position. OTOH, a transformer based volume control reflects output impedance of the source through its turn ratio. In normal, attenuating positions the output impedance of it can be lower than that of the source.
Maybe TVC won't be as low coloration as pot, but there can be issues like low driving capabilities and HF roll off associated with pot.
Anyway just to point out possible trade off between these two types.
I've set my mind in trying out TX102. Maybe I will consider a resistor based preamp too.
