How many pair of speakers do you own?

Five pairs as well, but I consider the speakers to be, at best, 15% of the sound of my system. Greatest effect is the room, followed by the preamp, then amp, then turntable/cartridge, then electricity, then speakers. Go figgur. My observation is that the distortions of loudspeakers are of frequency response and harmonically related distortions, the distortions of electronics are.....well electronic in nature, not musically related, as it were.

6 pairs that matter. There's a bunch of stragglers around here that aren't worth talking about, and eventually will be liquidated.

Eight pairs + one center channel. Of these, six pairs plus the center channel are in service in various rooms of the house. In addition, I have five subwoofers. (Not to mention incidental stuff like computer speakers.)

Four pairs,two pairs are build by myself.
Only listen to one pair at a time.
