Phono preamp or SUT for low output moving coil


I have three low output moving coil cartridges

  • Cello Chorale
  • Van den Hul Grasshopper II
  • Zu/ DL-103 Mk II

My phone preamps have phono input (Nagra PL-P and Conrad Johnson PV-7) but do not provide sufficient gain.  Looking for suggestions.   Open to any and all suggestions including stand-alone Phono pre into preamp line, SUT or electronic equivalent of SUT etc.

Viridian, As i see it, and as I just wrote it, yes, in theory the current driven phono stage presents a dead short to the cartridge, but in fact it cannot, because if it did, you would have a fancy mute switch. There's the rub with current drive.

Virudian, but how about a situation where the internal R of the cartridge is well below the input Z of the phono stage? These days that’s quite possible. Is that now voltage drive, or what? There are now several LOMCs with R less that 2 ohms and several “trans impedance” phono stages with Z greater than 2 ohms, even up to 12 ohms. I don’t know about the Sutherland in particular. Anyway, I only point this out because it may explain my actual listening experience. And those of some others. And what I hear is that each mating can give a qualitatively different result, sufficient gain is not the problem.
