2nd systems- who’s got one?

I had two separate systems of high-$$$ equipment.  My "main" system was the one I listened to 90% of the time.  I had great equipment that I replaced originally but couldn't bear to part with some of the pieces, so I made a 2nd system.  After two-years of barely using it (used it mainly for background music while working from home) it was a shame to let this stuff sit, so I sold it and have never looked back.  While if you can afford to have really good equipment in multiple areas of your home that may be nice, however I've found that for most of my listening enjoyment, my reference system is what pleases me.  And...  When I sold the 2nd system pieces, I had more discretionary $$$ to purchase upgrades or additional pieces to enhance my reference system listening experience.  

Four systems if we count the AV system, all in house. I think the idea came from the TAS days when there were upstairs, main room, and basement systems discussed in reviews.

It is useful for keeping items that may turn out to have unexpected synergies, and to have a variety of rooms to enjoy with music.

Selling off bits of systems now and then allows me to raise funds for the next round of mucking about. Or a nice bottle of something, Cheers.

Working on building 2 systems : 

neutral linear and flea watt. In addition, may get a desktop headphone system.

I currently have 4 systems.

Main 2 channel system (posted on Audiogon).

HT 5.1 channel system - Rotel pre-amp, Rotel 5 channel power amp, Velodyne sub, Oppo Blu-Ray player, Wharfdale towers, center channel, and bookshelf surrounds.

Secondary 2 channel system - Rotel Integrated, Linn Ninka towers, Oppo DVD, Cambridge Audio DAC

Office / Computer system - Marantz DAC / Headphone amp, Klipsch “the Fives” powered speakers, Beyerdynamic Headphones.

I rarely get rid of old gear and repurpose them in other systems elsewhere.
