Anyone Else Running Two Systems?

I am actually running three systems.  The first is my main system, which I consider to. be "upper mid-fi."  My second system, in our bedroom, if far more modest--the entire system costs less than most of my main system individual components--consists of a Rega Brio integrated amplifier, Paradigm Premiere 200B speakers, and a Wiim streamer into a Schiit Mimir DAC.  It provides very good background listening.  My third system was kept because it sounds so good and would bring very little in a sale, is in my office; it is made up of most of my 1990s main system, consisting of Infinity Modulus satellites (EMIT tweeters) with a DefTech Supercube 6000, an aging NAD 356BEE integrated amp, and another Wiim streamer feeding through my old Bifrost 2/64 DAC.  It provides excellent sound while I do household business and write letters.  Cabling for the two "secondary" systems is primarily Blue Jeans Cable, which I find to be quite adequate for these systems.

I have perhaps 4 systems.  My (apologies) "reference" system is in my living room (see my virtual system) and is where I go to listen. I am still tweaking this, trying to find the perfect amplification.  How do I combine best qualities of my 2A3 SET and C-J 62SE?

The 2nd system is in my open plan kitchen/dining room and is used while I am cooking and for dining.  That system is Eversolo A8, Elekit 8600 (NOS tubes, Lundahl etc. upgrades) and Harbeth P3ESRs.

My wife has an Eversolo Play CD with Dynaudio Focus 160 speakers. She sometimes like to listen to jazz singers (Norah Jones et al.) and 80's soft rock.  

In my TV room the TV and BluRay feed an NAD D 7050 with Audio Physic Sparks - taken over from my daughter when she took my Virgo IIs after I retired, and sold my NYC apartment.  

Three systems for me with my main (A’gon posted) system in a second living room/rec room, a second system in our main living room (AV and music), and a third outdoor system with three zones (porch, pool deck, and garage) that are managed by a very cool, very old Rotel speaker selector that manages impedance when multiple zones are playing at once.  The outdoor system is powered by a pair of Cary MB500 monos, a bit of overkill but lots of fun.

I have 4 my main in a dedicated room and 3 others built from equipment over the years that I couldn’t part with. Each has its own personality and all are tied to Roon endpoints. My main room has two separate systems, 2 channel and 11.2 surround. 

Count me in for four systems.

Besides my primary system in my dedicated listening room, I have two other systems that occupy other living areas in my home.  Lastly, I have a dedicated analogue/tube based system for headphone listening.

They all get regular use and I enjoy them all!
