Have you ever tried a pair of speakers and said this Is the last thing I will ever need.

Sound Labs. Maybe my vintage pair won’t last as long as something newer and the newer ones will be compatible with lower powered amps, but I sonically, I can’t ask for anything more. They leave all my prior speakers and most others I have heard in the dust and it usually isn’t that close. I could upgrade all other components many times over and I don’t think the Sound Labs would ever be a weak link.
I’ve had multiple visitors who own more expensive speakers leave with jaws agape and more than one who said, "I’ve got to figure out how to get some Sound Labs." Cheers,

@tubegroover  Funny, I used to own Quad ESL63USAs and now listen to Sound Lab A3s. The former were so limited in what they do well compared to the latter that I can't bare to see them mentioned together. The Quads were a one trick pony(i.e. midrange-centric small scale), but yes they do it great. The Sound Labs are transformative every day on countless recordings. 
If you ever get near Philly, come on over...cheers,

@jayctoy Why would you rotate, let alone so many? Do they differ in strengths/weaknesses that much? Surely something stands out as superior to your preferences, whatever they happen to be. Different strokes...cheers,
