Hypex NC1200: Quality of the implementations

Only if you are a dog or a bat named Eric.

Yes, and as seen on the permeability table, distance (air) is almost equal to aluminum, both vastly inferior to sheets of iron, steel or mu-metal.

Looks like mu-metal is one of the key components in perpetual motion machines.

jalejos is testing the Hypex NC1200 modules and the buffers designed by him for the NC500 in conjunction with Richard Doporto (Sonic Imagery).

For this, he is temporarily using a provisional box, the NC500 in stereo, until the design of a mono box for the NC1200 ends. That is why everything is so tight, it is too small.

The buffers are the same as those of the NC500 except for a few minor modifications, as he told me in the long email received in response.

As Maty commented a few days ago, I have finished the new monobloc aluminum box that will be compatible with the Hypex NC1200, NC500 and Purifi Audio modules.

The information will be updated on my new website www.atm-audio.com (formerly atmstore.es and acoustic-technology.com) in the blog section:

I ordered an Apollon Audio NC1200 Stereo Amp with the Sonic Imagery input buffer. Can’t wait to receive it.

Have measurements been done on the nc1200?
As it is said it should be better than the nc500?
From measurements it looks like the nc500 is better then the nc500. Is that true?

The nc500 should be about the same as the nc500.

The nc500 should be about the same as the nc500.

Haha meant NC400....

No it really was funny

Which with the Hypex design they have. Please look at the plots I showed of the LACK of RF coming out of the units. If you dont understand the plots please ask for clarification.

I agree that it was funny, but if it had all those little ventilation holes like a colander would have been even better (and it would have been the official head cover of my religion)

The first, the original, the expensive... the Bruno Putzeys implementation.

In this implementation there is a little linear psu connected to a 1200smps do you know the rason?

Thanks

Clean AUX power, better than from Hypex SMPS.

[ ...In attachment you can also find pictures of our new amazing product. It is called the PNC1200M mono blocks. PNC stands for Premium Ncore. These mono blocks are based around the NC1200 modules. We use Weiss OP2-BP op amps for the input buffer and a linear power supply for the input buffer stage and modulator stage... ]

Certainly to have a standby function compliant with EU regulations. The SMPS used doesn't have it embedded.

From the pictures, the SMPS aux seems wired the the amplifier module.

This looks more like marketing verbiage that facts, I hope you will as well relay my own marketing once I start selling products .

Apollon flagship PNC amplifiers also use a linear power supply plus Sparkos discrete regulators for their buffer and modulator of the NCore NC1200, with the Weiss OP2-BP opamps. As high end as it gets.

LPS and regulator.

Buffer board mounted on heat sink with NC1200.

And a clarified version of the stereo amp picture. In the middle, along with the big encapsulated LPS for the buffers, there is a smaller one just for stand by.

I only rely on independent measurements and subjective reviews from certain people I have confidence in.

After the appearance of PURIFI 1ET400A I lost the little interest I had for Hypex, Pascal, ICEpower...

And no interest in Hypex SMPS.

Nope, it seems to be there for the standby function. Look how things are connected, you can see all the wires.

As for the Hypex SMPS, which we have already proved to have some interesting design aspects, the use of the 7815/7915 as regulators is not too bad, provided the circuits downstream have sufficient PSRR. You can have cleaner power with other circuits (and again Sparkos is mostly marketing - if used properly the Hypex regulator is even better, and if one uses the LT3045/LT3094 one gets similar purity with a smaller expense, and in fact Apollon will move to the LT3045/LT3094) but it may or NOT be necessary. I am using external AUX power with my build only because the one of the Connex SMPS is not suitable.

The build is definitely impressive!

I am more concerned by the fact that the case is very small. There must be a horrible heat build up.
Maty would disapprove ;-)

Sacrilegious, you have directly or indirectly criticized Bruno Putzeys. Someone will call your attention and ask to be banned from the forum.

How long until Purifi releases an 1,200W @ 2 ohms version of their Eigentakt module? That would be end game.
