Glad to have found this thread. I've owned KLH Nines since 1972 and driven them with Futtermans H3a and Marantz Model 9 I am still driving the KLH Nines with the same Futterman (recapped of course) and of the 3 pairs I've owned I've kept one and had it refurbished by David Janszen. I donated an early prototype (used 4 large bass panels instead of the 10 now used) I had as well to David as a gift. I drive the Nines with the Futterman or Accuphase. I've heard just about every Hi End speaker made since I love going to audio shows and owned Sound-labs A-3s and as well as still owning Modified zA2.1. Once you listen to a Nine its hard to forget them. The cords to the power supply cans make no difference at all.

I just bought the above speakers, I like them a a lot , I am thinking if it’s possible to replace the power cord on the power supplies. On this speakers? Thanks B

Here is a link to an early pair of KLH model Nines showing a wholly different design in the amount of transducers used 5 verses 11, with 11 being used in final production units by KLH https://ishaenterprisesllc.com/ Having owned the Sound-Lab A-3 I found using one segmented diaphragm to reproduce all frequencies was not as fast or natural sounding as compared to 2 or 3 pairs of KLH model Nine (series/parallel) driven by a Futterman, augmented with JBL B360/BX63A Sub/xover driven by a McIntosh amp. Volume levels easily exceed 100db |
