According to the specs I've seen, the Shindo has an output impedence of 600 ohms and the GamuT has an input impedence of 20K ohms, which means there should be no impedence matching issues. I can't see how gain could be an issue, but neither GamuT or Shindo is much for publishing specs, so that's only a guess. If the Shindo does have too much gain, you could always use some in-line attenuators.
Shindo & GamuT - Comments?
I am considering an upgrade to my primary system - I would like to pair a new Shindo Vosne-Romanee preamp with a new GamuT D200i stereo amplifier. I love Shindo preamps and the V-R is the best one I can afford. And I am very pleased with the amplification of my GamuT D150i integrated, which I would trade or sell to get the D200i. But I have concerns about compatibility of the V-R and D200i in terms of impedance and gain. Can any of you offer guidance, either based on actual experience with this combination of components, or based on your knowledge of impedance and gain matching between preamps?
