How many speakers and AMPS do you own, and why?

I used to keep stuff, and I do miss a few items, my First system for instance, a Marantz 2020, Pioneer turntable with a Shure cartridge, and Advent speakers, but more for nostalgia reasons then anything. So I found it was much more useful to sell the old stuff and use the money to upgrade my main system.

Great replies thus far! Most get the drift....an accumulation of stuff not being used, for say, in a second or third system some place else in the house. Just stuff for whatever reason you cannot part with....

For instance, I have 5 turntables, all worth about the same, yet I can only listen to one...I realize I could sell all 5 and spend the money on one that may be substantially better, however I cannot bring myself to part with them...maybe I like the variety of having different types and/or flavors...

"So, having a bunch of stuff around is just having lots of stuff with different weaknesses."

Great point, and something I have not given much thought about....

I have 2 sets of speakers, 3 amps. Keep the extra speakers since major pain to box up and ship, three amps for back ups in case of possible power tube failures. I only have one set of boutique tubes for each, don't care to listen to second rate tubes.

OP,

Cool. I remember getting my first high end turntable… a VPI Aries and Van den Hull cartridge. My jaw dropped… goosebumps creeped up my arms and shivers went up and down my back… how was this possible? The background noise just disappeared… the bass slapped me in the chest… voices separated into individual singers.. lyrics I had no clue about suddenly presented themselves clear as day. OMG. How is this possible? This was the best investment I ever made! 
 

This was the same story for my first real audiophile tape deck, preamp, amp, streamer and speakers. Completely overwhelming. But, not from indiscriminating spending… but intense research and careful investment… 

Excluding the full 7.1 MARTIN LOGAN speakers and 3 YBA power amps driving them in the mancave…

- 4 two-Channel systems = 8 speakers and three amps ( one set of speakers are active)

WHY?
SIMPLE: I need them in different rooms
