Hello, new to the forum and loving all the info.

Has anyone used the model 30 with Klipsch cornwall Iv's?

Thanx

I think the products will look better in the flesh. Marantz generally don't screw up styling.

PS The hipster video ad for it is just garbage.
Except their AVR's are really ugly. But apart from that is usually looks ok. I have to say this looks better than what I'm used to from Marantz though.

Actually the Marantz Model 30 implementation of the NC500 OEM modules lowered their SINAD to about 75 according to Stereophile's measurements, which is a shame, since a top implementation such as Vera Audio P400/1000 of the same modules has SINAD about 101...

I suspect the decreased SINAD comes from the power supply noise at -75dB as can be seen in Fig. 4, and probably caused by the linear power supply toroid in the middle, even shielded with the steel cup.

Is it me or is it also a very small linear power supply for amount of power NC500's can put out?

I think the linear power supply is for the low powered parts of the amplifier such as pre-amp, electronics, etc.
The 2 NCore modules (top center) are powered by the Hypex power supply (top left).

Correct.

There's one Hypex SMPS600 for both NC500 OEM. Still underpowered.

It’s just the typical Marantz distortion factory HDAM saus. Just look at that barrage of transistors on the right hand side.

Oh jeez, I'm blind. But its still not very big. Each of my NC400's has one of those?

Yes. And the problem is that the NC500 module draws up to 700W in 4 ohms each, that is 1.400W for the pair, and the Model 30 power supply is 600W only... That is why VintageFlanker mentioned the modules are underpowered.

I also have a cosmetically poor, but electronically excellent Kenwood L-08C and L-08M pair in a mythical 110-220V configuration. Surprisingly, if I put my ear to a high efficiency tweeter, I can tell that the SNR is not as good as my Accuphase setup. At the listening position, I don’t hear any noise.

Kenwood was a big proponent of variable loudness and they actually had two dials to control the loudness; the frequency and the strength.[/QUOTE]

Kenwood (mostly thought of as not high end) made a # of products that were close to being high end (and probably a few that were, in fact, high end [with a few low cost modifications] if you were not name brand conscious). And they were innovative, such as the two dials to control the loudness (a sort of BASS BOOST Parametric EQ, if I remember correctly)

The Marantz spec is just [email protected] The PSU should be fine for that. Still, for that kind of money.. why skimp on the PSU.. Hypex has a 1200W version available, there is enough room, cost will not be very much more. They could have traded for some of those HDAM transistors ;)

At that price plastic is not ok IMO. I do not like the design anyways, Marantz can do better in that matter.
Saul Marantz had much more expertise than to make things that had the (lack of performance, look & feel) than these new Marantz products have.

Yes, that is the point. Marantz used a severely undersized power supply and choke the modules, and they specified the output power correctly then. Maybe it is not to cannibalize their more expensive PM10, also based on NC500?
