Many thanks to everyone for the advice. I think for the present I'll keep (and enjoy) the Jade 3s. And over the next couple of years I'll arrange to audition the Harbeths, but also Spendors, Tannoys, Fynes and ProAcs. No rush; its part of the fun of the hobby. Regards.
speaker upgrade
I would appreciate your advice on upgrading from Wharfedale Jade 3 standmounters. Current system is Cambridge CXA-81, miniDSP SHD streamer with Dirac Live, SVS sub, lower-end AudioQuest cables, Furman power conditioner and assorted acoustic panels & tube traps. Room is 12x15x8 with two open doorways, rugs, heavy curtains. I like the "British" sound - musical, not so bright. I listen to a lot of vocals of different types, for example Melody Gardot and Sinatra, but also Argentine tango (GoTan Project, Tangetto). Seldom crank it up too much.
Budget is, say, under $2,000 and used is fine. I've been thinking of a Harbeth P3ESR, but I haven't heard them. I may have someone interested in my Jade 3's so I may need to move faster than I might otherwise do. Any suggestions would be appreciated.
