You can do much better than a Node.
The Node is an excellent device for a starter system but with an amplifier of your quality the Node is not going to offer the best sound quality.
The Node does offer a lot for its price including a great app, and many different music streaming service options.
The issue with the Node is that it is an inexpensive device designed to offer good performance with mostly midfi gear.
The best choice would be a Innuous server these range from $1,400.00 devices up to much more expensive servers at $2,500-4k
The Innuous is very easy to setup and does require a Roon subscription which is $120 a year or $500 lifetime.
Roon itself is amazing the experience it offers is top notch it is easy to use and integrates perfectly with Tidal as Tidal is a partner.
If you have CD’s you can also rip them to the system and access them that way.
Sound quality of the Innuous gear is fantastic, custom built motherboards, custom designed USB card, and quiet power supplies.
The Innuous has a USB output which the Node doesn’t have and through Roon you can upconvert a 16 bit 44k digital stream into a psedo high res stream at 24 bit 192k up to 32 bit 384k and above.
In this way you can dramatically improve the digital sound of your system this is something the Node can’t do.
The Innuous gear is very easy to setup in less than 5mins you are running and streaming Tidal.
