New Audio Note M10

Audiohifi · 21st June 2009, 07:51 AM

This very high end preamp is retailing in Hong Kong for
HK$ 450,000. The power supply is advertised as even better than battery no matter what AC main you put in. The ps is internationally patented.
Any idea what is the circuit like, the impedance of the output transformer, etc

If patened, then there are patent docs to look at. That will tell us a lot.

"Patent applied for". They sound like simple series regulators. AN must be very proud.

A very cool link. Thanks.

The M10 is probably a bit different but the older preamp shuntregs around the ECL82 are very similar to the old patent. I would never have guessed that the addition of a single capacitor is patentable.

Hey, that's a major change in the patent world. Any change is patentable

450,000 Hong Kong Dollars is about £35,000 (UK, pounds Stirling) !!!!!!!!!!!!!!

For this http://www.audionote.co.uk/products/preamp/m10_01.shtml ???

Even allowing for custom cases for the pre and psu, heavy transformers and chokes, and decent pots, you could knock up something like that for £1600 or so.

Oh well, long live capitalism...

The high price is necessary to cover the patent fees

This is obscence pricing!
Cost more than the Mercedes C class!

Consider the amount of engineering and patents Mercedes had put into a car.
Also, pound for pound, with that money you get 3000 lbs of metal vs 30lb for a preamp.

Don't mention exotic metals in the amp, the catalytic coverter in a car has more precious rare metals than a preamp.
