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

@audiotroy  Good to hear…at least the C658 streamer isn’t worse than the Node! Do you have any idea how the DAC in a C658 compares to a SMSL M400?  Do you know what kind of power supply is in the C658?

I would look at the Evo when I get the funds to make a significant upgrade.

@tony1954 Yes there is a benefit in upgrading single pieces.  But there might also be future all-in-one unit upgrades too.  Components from different manufacturers don’t seem to work together seamlessly.  Plus there’s too many wires.

On my room, I’ve added area rugs, etc., but it’s almost all glass windows and doors.  5 sets of glass patio doors, and 7 glass windows/doors up to 8ft by 8ft floor to ceiling. Whether DIRAC can improve that situation I can’t say.

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.
