Cool... so on their site NAD lists the M33, M28, M23 and the C298 as their Purifier products. There is a design presentation difference in the two series. The C series is obviously designed to be heard not seen
.
I doubt there is an audible difference between the two series, but the M23 is $3499 versus $2199 for the C298. If I were wanting one to sit next to a M33 on the shelf then the M23 would make sense, but for my use the C298 is spectacular! Having a plan black box on the bottom of my rack providing power does not bother me
.
The M33 and the C298 have both won about every award that an audio amplifier can win. Unfortunately, good luck getting a C298 or M23 at this time. One dealer is listing the C298 as In Stock, but all others I checked are listed as Out Of Stock. All that mention the M23 state that shipping availability is unknown at this time
.

"NAD's UNIQUE IMPLEMENTATION
NAD’s renowned designers worked closely with Purifi Audio to customise the Eigentakt implementation to ensure every product featuring the technology would meet the high standards NAD is known for. For this reason, NAD manufactures its own Eigentakt modules rather than buy off-the-shelf."
