Yes really, and when isolated and being that the house is being refurbished (so no powerline which is the worst offender) as I've done it can't be knocked (literally).
The billy bonus being I got truckloads of the stuff, all new and unopened, for buttons.
Same with home hifi. The discontinued Richer Sounds 'Incognitio' system (aka Opus) offers 6 channels over Cat5 wiring, well, I got the main boxes / PSUs cheap as chips + spares,
the room controls were being sold off for buttons as they were the tabletop versions. And what is the tabletop version? It's a wall mounting version in a custom made table box. Unscrew
controller from custom box, bin custom box and you have a £100 item for £10! Yes it's well 'analogue' and slightly old fashioned but it's simple and that's the key. Each room can choose one of
6 channels, for 3 of them that's radio from a fixed tuner in the main cupboard, 4th is my (actual vinyl) jukebox, 5th a bluetooth rx with a modified antenna so it covers the house...
Best of all it works with any speakers you want to just reused my half decent Yamahas. No need to spend silly money or suffer tinny little pc type speakers.
