Roon for high end audio?

Not true at all,Roon  is by far the best most music organizer out there.Qobuz, and Tidal are huge  streaming libraries to complement Roon.the key is having the quality to complement hiend streaming 
to seriously compete with discs ,or Flac files.
for example I have the latest Bricasti M3 with Streamer card option.the M3 dac and streamer is a very good example of high end sound without breaking the bank.  To complement  a direct Ethernet cable is a must,from the router is necessary. I use a decent Quality $200 Wireworld Ethernet cable from modem to router ,from router to Ethernet switch to save $$ the top professional grade 30 ft of Beldon 500 MHz bandwidth , very important here the cheap $30 Ethernet hub is worthless l use the Uptone Audio,Ether Regen 
absolutely cleans the digital noise riding on the line and from there to the streamer ,it is now clean ,and a Wireworld $200 Ethernet cable to the streamer. This is the most critical cable  I have experienced ,I will buy better in the future, and under the dac an absolute must for top clarity and resolution is a set of 4 ultra Still points. My system sounds very good . Not lacking what so ever.
sure it could be better still if I have another $5-10k.  I have roughly 
$8 k  invested in the dac cabling,power cord ,plenty good for the moment and Bricasti is at the forefront and it’s a modular design 
with the future in mind.
 

Its your gear not Roon

The only downside to Roon is the software and it's total inability to get a grip on cataloguing classical music. However that is no different to all other software I have tried except Idagio but they only stream classical music, which is not enough if you have broader musical tastes.

IMO Roon is a MUST for the serious audiophile who is interested in digital music. It facilitates very high Fidelity music playback. You can run a Roon core IMO equally well on ani inexpensive NUC as a server streamer costing thousands. I know. I have done both. It is invaluable for music discovery. I don’t know what I would do without it. 

Chorus,

You just need to update your Zen to the 2.04 current version. You will have a choice between Roon and Innuos Sense. Select Sense and be prepared to smile. It sounds much better than Roon on the Innuos players. Also download the remote Innuos app. Roon is still a better interface in terms of features, but it sounds harsh and noisy compared to Innuos Sense.
