Looking for a front end streamer only.

I am looking for a front end streamer that I can get the cleanest sound out such as the Auralic Aries 2.1 or Dcs Network Bridge etc.I mostly would stream Tidal and Qobuz but would like Roon end point too. I have a Anthem STR integrated amp and Focal Aria 936 floor standing speakers. Mostly been doing Vinyl and Cd's. Looking to join the streaming world. Will buy a better Dac later. Don't want to spend more than about  6k. I would like to use my ipad for controlling everything. I have a dedicated ethernet connection or can do wifi.
I have been using a Linn Majik for about 2 years now. I just started the audiophile venture. I really like the Majik DSM as it offers everything you said you wanted, It is a very good streamer and is also equipped with a very good dac. It also has a 90 watt amp which makes it self supporting. It sounds very good running through a pair of ML ell 11 A's it can be used as a line source, active pre amp and is completely controlled by a iPad in my case.

ghjuvanni59, I did performed actual comparison test between Node 2i and Lumin D2 as well Teac NT-505.... and I have to tell you that difference in SQ between Node 2i and those two streamers is huge, not in favor of Node....FLAC signal could be the same but balanced design, better power supply and higher quality audio components make the difference. High end streamers like Naim ND-555 or Lumin X1 will makes cosmic difference.

As I noted above -  I own three streamers in different systems and have had the opportunity to compare them going into the same DAC using the same cabling.  The difference is quite significant. The better units offer more resolution which is nice, but the real difference is that they offer far more spatial information.  The Node 2 (as a streamer only - not using the internal DAC) sounds “flat” dimensionally in comparison.  The Node 2 Is a killer unit for what it offers for $500, but It’s no match for better units.  BTW - same goes for optimized Mac Minis, etc.  Been there.  

@mgrif104 THANK YOU. The notion that a server doesn't make a difference is a sad misconception. We can take customers through seven or eight different streaming options here in our shop and the differences are remarkable. 

+1 vote for DCS Network Bridge. I had Auralic Aries G2 before and DCS SQ is much better!
