Streamer Recommendations

@audphile1 I feel like  I have some decent equipment.  I do need a DAC and Streamer.  I have a few DAC's in mind. Does Lumin update the models but still keep the same model numbers?  Like you said an older model U1.  I have listed my equipment so far.

GR Research NX-Otica 

GR Research OB triple subs

SMc DNA .5 GT24 amp and SMc TLC2 GT 24 preamp

For that system I would suggest getting an all in one. Something like one of the hifi rosebunits used or eversolo for example. Start there on a used market. Upgrade when you are ready.

This used Innuos Zen would be a great choice at your budget level. It’s a very good streamer and comes with their outstanding Sense app that is arguably the best in the industry (and yes, the app matters a lot), and it also has onboard storage and disc drive so you can load your CDs into it and have all your music available at your fingertips. Pair this with a DAC that delivers the sound characteristics you’re looking for and you’ll be in great shape. Best of luck.

I would recommend a used Aurender. I still have an Aurender N100 in my headphone system. Excellent software, excellent build quality and first rate audiophile sound quality, as well as great service. I also own a Aurender W20SE ($22K) and have tried a number of streamers between $500 new to $20K in my system. Aurender is one of the premier audiophile brands and their flagships are typically used in high end audio shows as streaming source. 

Very soon the Bluesound Node Icon will be available. The software and dedicated customer service is really top notch. It is a balanced dual channel, dual DAC design and they have added a touchscreen for those who want it. It would be a great addition to an already established hi-fi system. I have a Vault, Node, Node2 and Node X. They have all performed far above my expectations. IMHO
