RE: Can anyone here explain "Current Drive" phono stage design?

"Current drive" or "current driven" is a term coined by some makers of phono stages, lately. I've read about several such devices. I agree, the term is ambiguous. If it is unfamiliar to you, as it is to me, then I would tend to think it's jargon concocted to infer that one particular design has taken a novel approach, in this case with respect to receiving the output from a low output moving coil cartridge with a low internal resistance/output impedance. Some of these same phono stages are said to "automatically" adjust themselves to the "correct" input impedance to suit the LOMC used to drive them. Thus one need not be concerned about phono loading, or so it is said.

You asked, "Does the term in this case mean a current output or a current input?" Input from the cartridge. Obviously, for LOMC cartridges. Hence, such a phono stage could be said to be "current driven".
