Having owned the M25 and M25 HD 2, I am lusting after the new M17 and M27. I know there is no reason at this time to change out my current set up. If I were buying new again, there is no doubt that I would snatch up the M17 and M27 based off my experience with the M25 and M15.


Anyone interested in purchasing my M25 and M15 HD 2
I'll give a good price on both that are under a year old.


Has anyone seen the picture of these? I can't wait for more detail to be released on them.

Cinenow France has posted a video from CES 2014 about those, and of the two new stereo pre- and power-amp products M12 ($3499) and M22 ($2499).


I don't understand French, but auto caption's auto translation gives one some ideas about them. (..Though, pretty sure he wasn't actually talking about "dog preamp" or of "revolutionized food".
) Also there is video of the connectors: XLR pre-outs and ins in M17 ($5499) and M27 ($3999)! Also M12 and M17 have touch screen displays in the front. Also the D-class M27 is sure to be much less back-braking component than the current M25.

Cool all digital class D! Do they use ICE Power! Also the screen is a copy from Classé? Are they manufactured in China?

Despite the sarcasm, I would hope that the amps were all based on Zetex that the M2 and 390DD are. But it seems kind of foolish to me that they are feeding the M27 with an analog signal. If it was a fully digital system I might go for it.

A couple of months back we visited the China factory that designs/builds the NAD stuff..
The new NAD components are awesome in ID and have some new techy stuff...
The surround processor does not yet have 4K capability but this board module which plugs in will be available in August..
The 4K board is going through some rigorous validation/certification testing. We have seen a proto of the board in action and the video looks excellent...

Just my $0.05.... :wink:

M17, 7 channel and no Dolby Atmos ??

What I find the most disconcerting on the M17 processor is that NAD stuck with Audyssey MultEQ XT. For a prepro at the $5500 price point, you'd expect at least MultEQ XT32 when you consider that it's beginning to show up on AV receivers in the $1300 range.
This product is a big yawn for me.

That M27 looks like a fantastic piece.

The Hypex amp modules are basically as good as class D gets (Icepower ASX2 is also up there; Abletec's stuff is on paper as well, but I've never played with one). The key phrase with Class D is "load invariant." Basically, any module that's load invariant has a chance of being great, because its frequency response will not change with the driven load. Common class D amps (all of them I know of except for the above three) act bad like tube amps. Their frequency response depends on the impedance curve of the driven loudspeaker. (Stereophile's "Kantor load" measurement shows these problems well.)

Obviously, only load-invariant class D amps are legitimately high fidelity devices. The common ones can be used just fine in designs that take their flaws into account, such as an active loudspeaker voiced using measurements of that particular driver/amp/cabinet. But for speakers, they're basically just inexpensive and more powerful triodes. A low fidelity, high coloration, solution.

As for the price, look at how much Hypex NC400 modules and matching SMPS cost on their own, and keep in mind you also get a nice case, 12V trigger circuitry (presumably, haven't seen the back), etc. Sure, the module is "different," but whatever.

Do we yet have verification that these are actual nCore modules (NC400, NC1200), and not UcD modules which incorporate some amount of "nCore technology"?

That is very disappointing if this unit does not have XT32.

Well, the press release says "Ncore" all over the place. Presumably, both NAD and Hypex have attorneys that vet press releases discussing licensed IP.

Other than that, who really cares. I'm highly skeptical that there's any audible difference between the two anyway. (Ncore probably measures better.) Both are low-noise, load invariant designs.

They say "nCore technology", which may or may not be the same thing, given Bruno's announcements some time back that the UcD's had incorporated some nCore technology.

I'd like some clarity, that's all.

In the years since NAD released the M2 "powered DAC" and M51 line level DAC -- both measuring impeccably using the Zetec 35 bit PWM process -- I have oft wondered if NAD might someday apply the same to a multichannel component. A 35 bit PWM pre/pro with state of the art room correction could be a real statement product. Maybe even better yet, make it a flagship AVR with the 35 bit PWM path all the way through the amplification stage, a la the M2.
