I have the 706S model. The speakers have excellent build quality. They are in my office system and I have compared them with NHT sb-3 and sonus faber minima. The jm's have bi-wire ability like the sonus and sound very much like them. The nht have better low end, but the jm's have more extended highs. Overall the chorus are a great value and ,in my experience, they can keep up with the more expensive speakers I compared they to. The cabinets are much better on the other two, but the sound is very close. I think you could be very pleased with any of the jm speakers. The power equipment I use is vintage mcintosh and vintage Marantz which seem to match up very well with the Chorus. I hope this helps. Regards
