Outlaw 2200 M-Block Amplifier Review

[x21]

Not mine
I don't think there's a single NAD component here nowadays -- a few have passed through over the years... they tend to not age too gracefully IME.

Don't get their receivers.

Don't get their receivers.

One of those (a NAD receiver, that is) did indeed pass through -- it was quite tedious to clean some very noisy controls & pots in it.
It's not here any more. I gave it to someone, although I don't remember to whom or what they used it for.

I love the sound of old NAD gear but man that power envelope system is dangerous. I gave an old NAD 2100 to a buddy to use as a garage stereo and it only took him one night drinking and tinkering in his garage to push it to clipping and smoke a tweeter. He said literal smoke came from the tweeter.

I have had three NAD amps from the c270 era on fail, all for the same reason: terrible thermal management and cheap construction. A bad combo.

Cheap capacitors are packed far too close to heat sinks and other heat sources. The larger Resistors run shockingly hot. So hot that as the c270 aged, a some power resistors on the amp board got so hot the solder melted. The resistors did not smoke, but burned your skin in half a second and heated the traces, etc.

The pcb boards all show areas of severe heat, even in preamp or buffer areas.

The pcbs are the cheapest I have ever seen and traces lift if you look at them. Add any heat stress and they are close to not repairable.

The circuited are very complicated and there are an incredible number of components like transistors, caps, etc than drift due to premature heat aging or just blow.

Never again.

Had a sunfire 2x300 with the class h topology. Great power and ran cold always. Lots of noise from the power supply in tests though I never heard it in use. At least with lowish sensitivity speakers. But when is developed a fault in that power supply it failed with fireworks. Kaboom. The output stage seemed fine but the power supply and regulation to it failed with smoke and sparks. The build quality and layout was also rather amateurish and cheap. For example the huge transformer had “shielding” just hot glued to the top of the el-transformer. No mechanical connection to the case etc. so not much shelling lol. And the input circuitry and speaker out wiring was quite close to the transformer. Nice. the ac filtering to the transformer was a joke…one cap and resistor on a 10c terminal strip screwed into the chassis a cm away from one of the speaker outputs. The star ground was an 18awg wire running across the screw terminals of the filter caps with every other ground wire wrapped around it plus another one screwed to the chassis. Yeah…wonderful.

Exactly, all NADs are built to fail. Good more people start to notice it. The x70 are the most stupid modes with class A modules packed in a box with tiny cheap electrolytics inside.

Sorry, ridiculous. Nobody would design their gear to fail. Not in the way you are clearly implying.

Waaay off topic . If you want me to create a NAD owners discussion I will happily add this to it but keep it factual and calm . Let me know what you want but no more on this thread thanks
