Well none of my systems are quite as grand as the second systems here (including my main system) but will list them anyway .
Spare bedroom / Computer room - This is my main place to listen outside of the main music room Joggler 02 converted to Squeezelite player , Perpetual Technology PA-1 PA-3 Sampler and DAC , AVI s2000 Pre Amp , netgear Modified Quad 405 , KEF 103 .
Kitchen - Joggler 02 Player , Micromedia DAC Cyrus 1 plus Power Supply , Logic DM101 / Rega B300 / Rega Cartridge , Rodgers Flat Wall speakers (around 1959)
TV Room - Amazon Fire TV box / BT Box , LG 4K TV 55" , Onkyo TR650 AV Amp , Harbeth Compact Monitors front speakers , Canon S30 Surrounds
Each of them is perfectly reasonable to listen to for long periods and give me the option I want of music in every main room .
