I use Sonos system because I’m lazy.
Owner has this powering system and wants to sell for $500:
Carver Dolby Pro Logic Audio/Video Preamplifier/Tuner CT-29v
Carver 5 Channel Power Amplifier AV-405
Rotel Six Channel Power Amplifier RB-956AX
Definitive Technology Power Field Super Cube 1 Subwoofer
Is this antique high-value equipment? With modern wifi systems I don’t think it is actually necessary for me to use the guys old stuff or if I’ll even use the existing in-wall speakers at all.
