This starts off really boring but will get interesting soon, I promise. And there'll be pictures!
This is where I started from: a few Arcam components and some speakers bought between 1993 and 1999, and then a whole slew of Sonos boxes rolled out across the house from 2006. The Sonos boxes are connected by cat5 cable, and the infrastructure works really well. The whole family (Mrs 49 and the two teenage 49 girls) loves Sonos. And why not?
Living room: Sonos ZP90 and Arcam CD73 (now defunct) > Arcam A65 > KEF iQ5
Dining room: Sonos ZP120 > Linn Unik (wallmounted)
Kitchen: Sonos ZP120 > Linn Unik (wallmounted)
My study: Sonos ZP90 > Arcam Alpha 5 > Musical Technology Kestrels
Mrs 49’s study: Sonos ZP120 > Mission
It was a combination of two things that got me interested in hifi again. Mrs 49 gave me a pair of Grado SR325is for Christmas 2011, and then I had my study redecorated in 2012. The study system soon moved on with the purchase of an Audiolab MDAC, Cyrus X Power, and a pair of Sonus Faber Venere 1.5s.
It was only then, in 2012, that I started getting serious about replacing the living room system, which is the main subject of this thread and will be very interesting (honest). The dining room system also needs upgrading.
Just recently I had the ZP90 in my study upgraded by Fidelity Audio (which was the subject of some fractious exchanges on the audio forum).
