How many pair of speakers do you own?

Hi,
Over the past 35 years I have had over 300 different speaker models through my reference listening room, models, not brands. I currently have 3 different sets of speakers that I play with. Once I find a set of speakers that works better with my reference equipment I keep that set and eliminate one of the sets of speakers that I consider not as good a match to my set up. My preference for the past few years has been high efficiency speakers that are matched up well to the proper amplifier.
Cheers,

5 pairs 1 center
EPOS ELS3

I have two pair. Dan D'Agostino designed satellite/sub system and Thiel CS2. Well behind many of you owning multiple sets. I am jealous!:) Budget and spouse allowing (there's the rub), I would buy more. Hooked on audio since 1975.

For 2 channels system, 3 pairs, 2 pairs floor stand, one pair bookshelf. In this case, I can change speaker from time to time (just like woman....)
