I hate wasting anything, including space, so I guess I am lucky that when I see something that I don't use it irritates me until I get rid of it. Usually it is somewhere I don't look at it regularly.
I disconnected my CD player 15+ years ago and it sat on a floor under a bunch of stuff so it didn't cross my mind until I had to get something on top of it and was reminded of it. For the hell of it, I turned it on and it didn't work. That day I dropped it off to Best Buy's recycling bin along with a couple of old laptops sitting on top of it (took out the hard drives first).
Now the only thing sitting around is a BluRay player that get plugged in when my wife wants to watch old videos that were transferred from tapes or produced on DVD with a pretty nice interconnect that I replaced with a better shorter one (taking the waste philosophy to an extreme). I can't stand the sight of it next to my stereo equipment, and even put the cable box on the ground below the cabinet out of sight (thank goodness it works via wifi with the remote).
1 turntable (interconnect to phono stage attached directly and comes with power supply/power cord)
1 phono stage
1 interconnect from Phono Stage to amp
2 cartridges (1 is never used, but is theoretically for emergencies)
1 integrated amp
1 set of speakers
1 set of speaker cables
1 power conditioner (came with a power cord)
2 power cords (1 for phono stage one for amp)
platforms under the speakers, turntable and amps that take up minimal space
That's it. I hate making decisions and if I had to think about which turntable, cartridge, system or whatever to use in different situations I'd be wasting WAY too much time and mental energy.
Same with records - if I don't play it, I move it out of the selection area to the end because I can't stand looking at it, and once I need that space, I'll sell or donate them.
I guess I am a reverse hoarder, and yet my wife doesn't throw out empty pill bottles and I get anxiety whenever I have to get something out of one of her "junk" drawers.
