All-In-One (NAD C-658) vs NODE N130 with Separate DAC and Headphone Amp


Right now I have a NODE N130, upgraded with a linear power supply, and a SMSL M400 DAC. THE M400 doesn’t have a headphone plug, so I’m looking at a headphone amp, such as a Singxer SA-1. But, I’m wondering…how would all that sound compared to a NAD C658? Anyone make that switch?

The reason I’m asking, it that there is a convenience factor in having everything in 1 box. Right now I have to use my iPad to control the NODE, and a remote to control the volume on the DAC. Adding a headphone amp is another system.

I haven’t read rave reviews about the NAD, but it has DIRAC, which might help in my large room full of windows and hard surfaces.

I might add that I have 2 powered B&O speakers, and 2 powered subs.

OP, it seems like you have some good questions. I found the C658 thread on StereoNet to be the most informative and helpful. You may have to register as a new user since there’s a page limit if not logged in. If wanting to stay with the all-in-one route, as well as with NAD, there’s also the newly released M66 (but at more than 2X the cost). DIRAC helped my situation when I didn’t have room treatments, but I slowly stopped using the more I added diffusion and absorption. Like all things in this hobby, it depends on your situation and preferences, but it does seem like DIRAC could have a positive impact given your situation - especially if you purchase the full DIRAC Live version.

I uses DIRAC in my main system.  I like it, but the improvement is pretty limited to the sweet spot.  Since both components are made by NAD, the one with Dirac should sound better, but while I have direct experience with the Node, I don't with the all in one

@toro3  Thx I am working through the thread you mentioned. DIRAC might be an upgrade for my system.

@mahler123 I’d like to try DIRAC.  Good to know it’s just for one spot.
