Default HiFi over WiFi

I'd like to place my digital sources far from amplification and speakers so I'm thinking to go wireless. The system should look like this:
Source side:
CD player --> spdif --> WiFi transmitter

Amplifier side:
WiFi receiver --> spdif --> D/A converter --> amplifier --> speakers

Bluetooth could be used instead of WiFi.

Is there a project or kit to build up such a system?

Best regards.

Paul

Do they have SqueezeBox over there? That's what you need.

No, Squeezebox acts as a music client and needs a music server running on a pc. I need a wireless spdif connection.
I have found this:

but the transmitter only accepts analog and the receiver has not a digital output.

Ideas?

I know this is not exactly what you had in mind, but the $100 Apple Airport Express has optical SPDIF output. True, you need a computer running, but then again, the ability to sit with your laptop and play music wirelessly off hard drive seems more desirable than swapping out CD's.

Less handling of the CD is better, IMO.

If you insist on the hardware CD player, I would opt for optical transmission, and tuck the cable into the room edges.

Roku devices are similar to squeezebox, they need a media server running on a pc or mac. Thanks anyway.

I need a wireless spdif connetcion. Wifi, bluetooth or infrared could be a solution. Do you know a project, kit or commercial device ?

Default One option

Do you have google?

One option is to get yourself a pair of wireless speakers, and open them up in order to tap the analog signal into your amp.

There are bluetooth transmitters and receivers out there, I found one after a 2 second search on google.

blutooth tx/rx

Belkin Tunestage

iHIFI Transmitter

iHIFI receiver

So what you want is a bluetooth receiver with a digital audio output to feed a DAC- here is a reference design

edit- none of these products require servers or computers.

Well, since this is a DIY site, have you looked at this neat little chipset:

There are some eval-boards too I think.

All the devices you listed only accept analog signals, so they don't solve my problem. By the way, I am able to use google...


OJG:
That's exactly what I need !!! I only hope that the evaluation board is not too expensive... THANKS!!!

The Nordic nRF24Z1 evaluation board costs about 400 EUR (more than 500 USD). Too expensive !!!
In this DIY thread a project published by Elektor is suggested:
http://www.diyaudio.com/forums/showt...ht=#post271120

Has anyone tried it?
