Need recommendations for a streamer

I love the optical isolation from Sonore but I use Roon. Not sure but I think it can do streaming w/o roon. You might need computer then.  Innuos would be nice choice. Hear their app is very good. Ephoney is good too. Not sure of the spelling there 

Don't be fast to dump your Freya+. Paired with the M1200s? Yum.

IMHO Try your darnedest to avoid WiFi. Run a cable. (CAT6 is good for about 300'.) It takes time, but you get used to drilling holes through your walls. And floors. And those long drill bits are cool. 
 

Your DAC has an I2s in.  You should find a streamer with I2s output.  Ps Audio is coming out with the AirLens in October for $2K.  It will galvanically isolate from the wired ethernet..not sure about wifi..but personally I prefer wired if I can get rid of ethernet noise and that will be what the AirLens does..then I2s out and that should go directly into your DAC and since  I2s carries all clock information, the DAC doesn't have to reconstruct the streamer's output.

@jasonbourne52 and inexpensive.

The Node and the iFi are both competent excellent streamers!

Bricasti M5 Network Streamer took my streaming to another level. Only an Ethernet cable, no Wifi, no computer cables,  just a network connection. Should be a good companion to your Terminator. Check it out
