HoloAudio STREAMER is out now

@doni I am not fully knowledgeable regarding all the technicalities and differences. Someone else here may be better at explaining them. But I will give it a shot. 
Toslink is a unque optical protocol invented by Toshiba. 
Toslink cables are usually of shorter length than what optical cables can be. 
There may be bandwidth differences between Toslink and optical. 
I believe related to the above, there are differences in how the Toslink and optical signals are processed. Others should comment on this. 
I hope that is somewhat helpful. 

For DAC owners that seek a Swiss army knife for streaming/DDC this seems a great value proposition. After digging in I've learned the USB and clock implementations are inferior to those included in my DAC so scratching from my list. And the streamer search continues.

Anyone try the Holo Red streamer yet?

Some folk over on Head-Fi are using/discussing it, I believe.  Check out the “Dedicated Source Component “ forum.

I listened to the Holo Audio streamer today and it was amazing. It is quite nicely made and heavy, too. It was delightful sounding. Went through a Bent TapX preamp into some Coincident tube amps. Wow.
