Hi,
My recommendation would be very different. Spendor or Harbeth. Neither will play as low as the speakers you mention, but both will have truer tonal accuracy and better low level resolution IMO. I've never heard any other speakers that do jazz as well as Spendors, and I love jazz. Don't have as much experience with Harbeth, but I suspect that Harbeths would give Spendors a good contest with jazz recordings.
