The NAD M27 is 7 channels.  The Cherry Amps are 2 channels (also offered in higher powered Monoblocks, same specs otherwise).  Cherry MEGA specs based on 1800W transformer and double cap upgrades.  The Parasound A51 amp is 5 channels.

Just the specs first....  We can compare other factors later, such as subjective sound quality and price.

Before we get into prices and sound quality....

Looking for suggestions on 2-ch amp comparisons.  Is there a model you'd like me to compare against Cherry Amplifiers?

Thanks.

Nuprime Evolution One and your Megaschino. I'm very curious.
Thanks Tommy.

I’m in Seattle. Where could I hear your amps. I’m about to buy the Nuprime Evo.

Thanks Tommy. Tech details of Megaschino are looking very fine. Next on my list is the sq. But in The Netherlands that will be a dealbreaker. Evo one will not be the problem but the Megaschino will be a challenge.

We offer a 30-day in-home trial period.  You can compare a Cherry Amp to the Nuprime in your system!  Maybe there are Audio Circle members with Cherry Amps in your area.  What Cherry model(s) are you interested in?  We have some demos available....  Thanks.

I have no Idea!  My speakers are KEF 900s. What do you suggest comparable to the Evo?

How about a Stereo Maraschino (STM) or Maraschino Monoblocks (ILM, DTM, or GCM)?  Plenty of power, performance, and Sound Quality!

There's a KING STM on Amazon Prime, by the way:

I'm not sure about Amazon (the USA faction) shipping to the Netherlands, but we sell direct worldwide, and we have a KING STM demo in stock from a recent upgrade.

Hi Tommy,
ehh...look at my avatar... those are my speaker: Apogee Full Range. They need a lot of current.

Any KING Maraschino since they use our 1kW 60V power supply.  Rated power for 60V Maraschinos is conservatively 400Wpc into 4Ω.

Very nice speakers, by the way!  Can you post a photo of your system here?

What is different on this amplifier, compared with previous NAD products, is the implementation of Class D amplifier technology licensed from Hypex of The Netherlands, from its state-of-the-art nCore line. Hypex is one of several companies that develop Class D amplifiers, but its technologies are the only ones found in notable audiophile products like the Rogue Pharaoh, B&W Zeppelin, and $12,000 Theta Prometheus mono block. The distinction here is that NAD does not purchase Hypex amplifier modules, but rather designs a homegrown amplifier that utilizes Hypex nCore technology through a license agreement.

NAD has implemented some of its own design technologies, too--including the input stage and the switching power supply called PowerDrive--but the Hypex self-oscillating output stage, which is a big portion of the nCore advantage, is utilized.

It must be Hypex NC500 with NAD buffer/input stage.

So it's the same circuitry as yet another pre-fab module amp.  Guess they're trying to find new and exciting ways to avoid designing their own amplifier circuits.  Doesn't anybody actually design their own amps anymore?  That was rhetorical since we know Cherry does, ....and Mark Levinson on their $50,000 amp, although they're now owned by Samsung, so that level of design might be going away there (:

It is a logical decision. The Hi-Fi and High End market is getting smaller and the prices do not stop going up!

Only great Asian cities are interesting markets and not Europe/NA, that is the true.

People have become accustomed to badly recorded music and low/very low dynamic range that does not need a good equipment to reproduce it (it is even counterproductive).

They do not enjoy music, they only consume it as if it were fast food.

You should know that several companies here on AC do so.

I'm in Seattle. I have Maraschinos in 2 systems, King Monos and STM. You're welcome to come by for a listen.
