Has anyone ever actually poly chained two or more Sirins together? Any issues or problems using them in that way? I'd love to hear an example.

The sound of the Sirin is starting to grow on me, but I'm missing the extra polyphony/voices. Just not sure if I should fork out almost another grand for one to try it myself.

Or wondering if I should go for something completely different that isn't mono.

Can the sound of sirin be compared to anything else that has more voices? Subsequent 37 maybe?

Thanks!
