Roon supports Devialet AIR

[Saunter]

Hello everyone,

I would really like some feedback and advise as to how to get my set up sounding good.

I am running ROON on a dedicated i7 NUC feeding my Devialet 400 using direct ethernet connecton.
I have excellent power and speaker cables and the speakers are Lenehan Audio ML2 Reference.

It all works superbly except that i am not very happy with the sound quality and i know that it is not due to the amps (obviously) or the speakers.

The room is large and well damped so it is also not the culprit.

The sound is flat and a bit brittle sounding with no real sound stage depth. Highs could definitely be a bit sweeter.

I am pretty sure this has to do with the digital front end. What can i do to make very noticeable and obvious improvements to the sound ?

Should i add a dedicated power supply for the NUC ?
Should i do away with the ethernet connection and use USB ?

I don't really know but i am a bit frustrated since everything a read assured me that going the dedicated ROON ROCK NUC would be a large improvement.
To be truthful it sounded better fed from a laptop running fidelizer..

Please help with solid advice if you can.

Thanks a lot
James
