Planning to go from Audirvana + on Macbook Air usb out to TOS optical in on amplifier.

 

Is there a recommended box for this job?

I'm not the one to get into technical specifics, other can do that, but it is my understanding that optical is not a preferred method in the audio signal chain. At least not in higher end audio, if that's the goal. Is there no other method available with your equipment?

You need a USB to SPDIF converter. IFI makes one (iUSB) as do a few other companies including Musical Fidelity.

Mutec MC-1.2 will do the job.

 

Galvanic isolation on the USB is a bit of must these days, then MC-3+USB. That device will re-clock TOSLINK, so for a lot extra price, it also does a lot more. No problems about 96, it's a common max for Toslink receivers, Mutecs can handle no problems there. No drivers are required for MAC and are recognised by Audio Midi.

@kilroy

Toslink is the forgotten child of digital audio but if treated correctly (perhaps with re-clocking), it does have the big advantage of eliminating leakage currents. Compared with copper coax with leakage current (and ground loops) versus a de-jittered (without going to extremes) optical would it work out better?

 

I hope to try this after 2016 Christmas and will report on a different thread.

Brilliant, thanks guys.

 

Of course Mutec, Christian the owner is like the Swiss Army Knife of connectors guy. I know him well from AES trade shows. I will shoot him an email.

 

Thanks again.

 

This also look like it can do the job. SOtM dx-USB HD, Digital-zu-Digital-Konverter: https://www.ebay.co.uk/itm/281390987207

 

But will try Mutec first.

 

I wonder if I can I transmit the signal over wifi from my mac to present a USB signal to the Mutec USB input? If I can't it means I have to have a Mac (mini or one of my old laptops) running Audirvana + situated near my hifi.

It's also just occurred to me that buying the very cheapest TOS link cable on amazon perhaps wasn't the best plan. I might try another cable before giving up on the Chromecast Audio's 96k optical output.

 

And I read somewhere that the wifi signal strength (mine is a little weak) and some router settings can cause it to fail.

Buy your Toslink Cable from:

 

mycablemart.com

 

These are the same high-quality Toslink cables that Kimber sells for 10X mycablemart's price!
