Well even though you have wifi you still need something to read it and translate to an audio signal for the amp.
I guess depending on what you are streaming there are two relatively cheap options.
Google Chromecast Audio streamer.
Bluesound Node streamer.
Both will work on Wi-Fi, both will send an analog RCA output to your receiver.
Both can be controlled by an app on phone or tablet.
Really depends on what you are streaming as to which might be best option on the cheap.
One thing I really like about the Chromecast is it is tiny and you can hide it behind the receiver so keeping that vintage appearance vibe.
Either option should be a lot better SQ than a bt receiver.
What is your budget I guess?
