I just want the music to sound as real as possible
The devil is in the expectations. : )
Your Magnepan 3.7i's are excellent...but the Node 2i, NAD integrated, and Mogami/Monster cabling are not equals (of your speaker).
Between the amp, preamp, DAC.. looks like close to $15k.
Likely. Make sure you address power and cabling as well.
The best presentation I've heard with Maggies has been a McIntosh stack. ARC is another pairing commonly seen. Mentioning both, in case you are open to options other than PASS.
