Sorry I missed this thread until now. I purchased a pair of Ref 9K with matching stands in Jan 2019 and have been very happily listening to them since. I started off with a new Accuphase E-280 integrated and after 3 solid-months (24/7) of break-in & listening I was not happy. So I listed both them both for sale and told myself I would keep whichever one did not sell first. The E-280 went very quickly. I then used a Bryston BP-25/4B-SST and was much, much happier. A good match. Several months later I decided to roll in my tube amp, and, voila, wonderful match with the Cary 20wpc Class A Rocket 88 amp & SLP-98P preamp. Stunningly good. Additional upgrades I made were, 1) filled the stands with sand & lead shot. A nice improvement in bass extension & overall clarity. 2) put Herbies large dots between the speakers & stands. 3) the biggest improvement - upgraded speaker cables to WW Silver Eclipse bi-wire - MSRP same as the speakers. This past May I rolled in a PASS Labs INT-25 (25wpc). While different, it is every bit as nice as the tube combo and adds a bit of additional solidity in the deep bass. I've owned this particular pair of speakers longer than I've owned any pair of speakers in the last 40yr of this hobby, so I guess you can say I've been pleased. I'm in the midst of deciding between totally new speakers or just adding one of the new, small DSP controlled powered subs. If new speakers, the Ref 8K is high on the list, though I've never been able to live with a floor standing speaker for long. No hurry. The Ref 9Ks provide terrific SQ with the classic jazz, class rock & classical music I listen to. Plus, the fit & finish of these speakers is as good as I've seen. Highly recommended.
