Shindo & GamuT - Comments?

Apologies - In my original post, the last phrase of the last sentence is incomplete. The following was/is intended for the aforementioned last sentence: Can any of you offer guidance, either based on actual experience with this combination of components, and/or based on your knowledge of impedance and gain matching between preamplifiers and amplifiers?

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.

Jmcgrogan2 - Thank you for your comments. I was pretty sure there was not an impedance problem, less sure about gain. It is my understanding that the gain on the Shindo is fixed and that the gain on the GamuT, both the stereo amp and the monoblocks, is adjustable to three different levels. Of course, finding out what those specific gain levels are and whether or not one of those levels would allow the Shindo and GamuT to shake hands well without in-line attenuators has been challenging so far. As you so correctly pointed out, neither of those companies, especially GamuT, publishes much in the ways of specs.
