I agree that the US Shindo operation doesn't give customers a lot of latitude or help when it comes to matching Shindo with other components. I will say that Glen at Arizona HiFi is very helpful and I have little doubt that he would help me try to assemble the best system, even if it mixed Shindo with other components.
However, for speakers, the distributor and dealers typically point you toward Devore, A23, and Shindo. That means your choices start with the $13k O/96 and jump to $35k-60k+ for the A23 or Shindo line. I recognize the intent to protect the Shindo sound, but I also agree with Paul that it would be smarter of the distributor to give the customer more "acceptable" options in their price range, even if not a brand they distribute, especially since they offer so few options for speakers.
Paul and aurthurs, I know you've already recommended Westminsters as matches for Shindo amps, without reservation. You each have the Westminster GR, but do you have any idea if the SE model would be a good fit for Shindo amps? A used set is more in my price range. I saw that Tannoy recommends 20 watts minimum for the GR and 50 watts minimum for the SE. Also, do you know why the difference between the two?
