Adding wireless speakers to my current, vintage analog system.

  I haven't used wireless speakers myself, but there are are a lot of theoretic advantages.  One would need less power and they eliminate a crossover, and there are obvious space saving advantages.  I've heard the KEF and another smallish powered speaker and they have a surprising amount of bass for such small units.  I just don't think that thee is a way to work your vintage AVR into the equation.  You could perhaps use the preamp section of the AVR, if it has pre amp out, but then you are attached to the speakers with wires, and you want to avoid that

I thought there were Bluetooth transmitters which take a receiver signal and translate and forward a digital signal to wireless speakers?
Sort of a reverse DAC - an ADC if you will. Or did I just make that up? 

I’m more confused now then when I started this thread

You can get a Bluetooth receiver , such as Audioengine, and it will attach to your receiver via RCA cables.  You can transmit from a Bluetooth source, such a cell phone.  The signal will go to the Bluetooth receiver which yes has a DAC inside.

The DAC will send the now analog music signal via aforementioned cables to your AVR, which will then send it to your speakers, via the cables that attach the speakers to the AVR.  I hope you haven’t got lost yet.

  What you CANNOT do is send the Bluetooth signal directly to your speakers because your speakers have no way to receive and then amplify the signal.  In your original post you said that you wanted to transmit wirelessly from your receiver to speakers.  I suspect what you meant to say was you wanted to transmit wirelessly from a source, such as a cellphone, and otherwise keep your present system ( receiver and speakers).

  Pick up an Audioengine (I have had one for several years in one of my systems).Plug it into your receiver, stream from your phone via Bluetooth, start enjoying music, and relax

Thank you all for taking your time and being patient wth me!

mahler123:
I guess my questions are confusing as I’m not yet familiar with terms and technology, or maybe I expect more than what’s currently possible.

To clarify: I was wondering about both, wirelessly to and from the receiver.

Receiving:
One of the questions I have now is if it’s worth skipping the laptop and stream "directly" to the receiver, and if an added Bluetooth receiver/DAC is the only/best way to do that in terms of sound quality.
I understand that it’s streaming to begin with and probably one way or another always inferior to wire-connecting a CD player or a turntable. So I guess this part of the equation is more about convenience.
I just wonder, if I were to get a Bluetooth receiver, what brand/model folks here recommend (best DAC, ease of setup and use, stability of signal, least amount of footprint...).

Sending (to speakers):
I understand that I cannot send sound directly from my receiver to my current speakers. I’d have to get wireless speakers, which seem to have wireless receivers built in (making them capable of receiving a wireless, digital signal). In addition I probably need some sort of transmitter connected to my receiver if I want to send a wireless/digital signal from my receiver to the speakers (when playing my turntable for example), correct?
Do I need to match the transmitter brand to the wireless speaker brand (proprietary technology) or do I have a choice, can I mix and match?
Either way, what wireless speaker and transmitter brands/models do folks here recommend (sound quality, uninterrupted signal, ease of setup and use...)?

Also:
I also heard that small devices can be added to existing analog speakers to make them capable of receiving wireless. Does anybody here have experience with that? Is it complicated? How’s the sound quality? What do folks here recommend?

New receiver?
I start wondering if it would be worth looking for a newer receiver with the desired technology built in.
Are there receivers out there that can match the sound and looks of my current setup?
Would I need to match receiver and speaker brand (proprietary tech)?
If I invest in something like that, do some of these come with separate/multi-channel options – so that I can control the volume of one pair of speakers independent from another pair of speakers?

Thank you all for sharing your advice and experience!
I’ll be happy to share mine once I get to a satisfying solution.
