Bluesound mode not really cutting it

I have some experience with the BSNode.  It was IMO "unresolving".

I have tried a few different streamers and under 2K my favorite (for now) is a PS Audio AirLens. I was skeptical about it's claims but their return policy made me willing to give it a try.  I kept it :)

Except if you have any local files the Airlens will not play them without a seperàte server and DLNA.

The Node will.

For your budget new I’d get an Innuos Pulse Mini and an external LPS from Teddy Pardo, LHY, Sbooster, etc. that would be mandatory for best sound.  In addition to upping sound quality significantly you’ll get their excellent app that won’t be a letdown coming from Bluesound’s likewise very good app, which is not a small consideration.  Alternatively you could get a used Innuos Zen for around the same price and no added LPS required.  Hope this helps, and best of luck. 

The new Bluesound Icon is scheduled to come out in November.  I have the node 2i and will be interested in seeing the reviews for the new Icon and perhaps purchasing it.

I'd probably toss the Mac152 and get a tube amp.
