Transformer volume control with Tubes/Quads?


Has anyone heard this combination?

TVC's, in my experience, are more sensitive to the source than the amp. If the source has an output impedance (Zout) less than 200, has a Vout higher than the sensitivity of the amp and is DC coupled, there shouldn't be a problem.
I have been using a TVC with my ESL 57s for about 5 years and am very happy.  Great transparency.
