Do you recommend using the Bluetooth adapters for older receivers? None of the three I currently have have bluetooth.
You could, but if you want something that's more full-featured and can play Pandora/Spotify (not natively), AirPlay, Tidal, Deezer, Bluetooth, XMSirius, USB input, Server, etc- a Yamaha MusicCast piece like the WXC-50 is a good choice.
Sirius is one of the only streaming services that requires casting TO the Yamaha & brands other than Sonos because Sonos had the agreement in place before the others came along, but personally, I like the Yamaha more than the Sonos and I use the WXC-50 in my system.It also has an optical an analog input, if you want to play TV audio or use it as the hub for additional MusicCast pieces around the house- you can use the phone/tablet app to group the zones and control them from anywhere that the WiFi reaches.
If you just want to use Bluetooth, the Miccus is the one I have used, but not in more than one zone- it has optical and analog inputs, killer range and can be used as a transmitter or receiver, so you could send the source material (music or whatever can come from the receiver's Rec output) to a location that, according to their specs, can be up to 300' away (depending on what's between the transmitter and receiver). It uses Bluetooth 5.0, IIRC.
This is the one I have used and the first time, I needed something that could be used to receive audio in a school gym that has a full-sized basketball court and when I tested it, it never dropped out, even though I was outside of the far end wall, which is concrete block. In fact, it has to pass through two other concrete block walls to get to the gym, which amazed me because, until earlier in the morning I ordered it, I KNEW BT sucked. After reading about BT's improvements and later that evening, I found that I was wrong.
