Coincident speakers 14 Ohms - What amplification to use when streaming Tidal.

Your speakers are made to be used with very low power amps like SETs.  I don't know if you would enjoy that sound more than what you've got.

If atmasphere doesn't chime in I would message him.  He is a proponent of high sensitivity/high impedance speakers.

The Bluesound Node 2i would work for your streaming source.  It's really easy to set up and use.  It can connect with your  WiFi router either by WiFi or ethernet cable.  You download an app to your phone or tablet and control it with that.  If you have any problems someone here could advise you on where you're going wrong.

I don't know what the difference between the Node 2 and 2i is but you can probably pick up a 2 used here, if you want to save a little there.
