JM Labs-Focal: Chorus 726S or 806V or Electra 906?


I am interested in purchasing a pair of Focal speakers and can buy the Electra 906 (used) or Chorus 726S (dealer demo) or 806V (new) for about the same price. I would be very grateful for advice as to which one. They will be powered by a NAD integrated amp. I listen primarily to jazz and classical. I have a pair of Daline 3.1s that I love. Which speakers might sound closest? Thanks so much.

Thanks so much for all of the input. Is there a significant difference between the 706 and 806?
I have not actually heard an 806v, but doubt there is a significant difference. Probably the finish is the biggest change since the drivers are identical.
I own Cobalt 820's and Focal 906's, in addition to ML CLSiiz's, and Cain & Cain Abby's. It's 906's hands down, but I've obtained best results driving them with 100 watts Class A via a Threshold T200. The Cobalts have been relegated to rear channel surrounds, even though they obviously produce far more bass than the 906's.

I'm not so sure the NAD integrated is capable of driving the 906's and featuring them at their best, but they're the better speaker to my ear. Very hot speakers, and a great buy used!
