Earlier there was a post regarding DOZ Death of Zen, were someone was asking a question about DOZ.
Well there actually is a DOZ by Rod Elliot.
http://sound.westhost.com/project36.htm
The web page is critical of the Zen designs as being less than Hifi.
After reading the article, it almost seems like "He" could teach Nelson a few things about designing amps.
Kindof amusing.

Yeah. Rod's a nice guy, but he's rather a "hifi" objectivist. So it's understandable why he would be critical of the Zen designs. But I don't see that there's necessarily anything to be critical of seeing as the Zen was more of a philosophical exercise and wasn't making any particular pretense of being "hifi."
Yeah. That's because I think Rod was looking at the Zen in a rather different context than was intended.

Not hard to do seeing as Rod has JLH's classic amp on his website as well.

And for the lazy...
DoZ:
An externally hosted image should be here but it was not working when we last tested it.
JLH:

For those who are interested, there is a later, more
sophisticated (read: complex) version of the JLH whose
output is direct coupled. You can Google it right up, or maybe
some kind soul will post it, as I don't have it here at home
with me (read: too lazy to do it).
/pass/ Doesn't get excited over the superiority of 3 stage
designs versus 1 stage designs, and wonders if HaloJoy will
ever come back.

Well, thats superiority in numbers.
I have rarely listened to a more pleasent sounding amp than the Zen (hope the SOZ is even better in that aspect), and as stated in the pass vs. bryston thread...who cares about an amp being accurate, its gotta be pleasent and involving!!!
I have compared the zen to jmb (from berlin), and my verdict was that the jmb did as well as the zen, but not better. Considering the pricerange jmb is in....the zen's are maybe not that bad after all. Single gain stage or not.

As i remember it, the original article by Rod Elliot about the DOZ was rather harsh on NP....
As an old friend of mine once told me:
When people state the obvious.....its usually not so.
He gave a good example:
The biggest newspaper of the ex-USSR was named Pravda, in russian that means truth, wich obviously it should have been.
Now think of the title Rod Elliot chose once again.

Regarding Rod Elliot passively trashing Nelson Pass's designs... Bah! Unbearable nerds often have little or no tact, and many times they illustrate their inability to read--yet they want you to believe they are extremely smart. Of course I'm being satirical here...
Doesn't the text for the Zen series even point out that it isn't claimed to be the best amplifier, etc, etc... but that its purpose is to illustrate the simplest functional audio amplifier for DIYers? I seem to recall reading something like that.
Fortunately it seems that Nelson Pass somewhat has a sense of humor about himself--a rare trait among engineers.
I have an amplifier that is much like a Zen (though not identical)--complete with MOSFETs! It is most certainly the warmest and coziest piece of equipment I've ever heard. "Musical" only begins to describe the way it sounds. The specs are absolutely horrid--but I'm not an HP Distortion Analyzer, so I don't care!
The distortion value does not always have a direct effect on the sound. Just look and listen to some of Carver's contraptions... *toilet flushes*

I recently heard an Audionote analogue set up at a hi fi show - for me it was clearly one of the best rooms. The immediacy and transparency was quite extraordinary.
This was their middle of the range gear probably£10000 all in.
They told me that the distortion on their amps is up to 8%, but they ( and their customers I guess ) don't care because the sound is so good.
I agree some of the big name, AB 'low distortion' rooms were quite frightening.

Once again...
There seems to be an forever ongoing war between spokesmen for the different technology approaches to our common goal- listening to music at home.
I came across Mr Pass designs in the seventees, retailing Treshold amps in my Stockholm store. As far as i recall he ventured into several different technology branches, always with a good end result. So, i suppose he agrees with me, any approach, bipolar, fet, mosfet, tube or whatever is good, as long as You do it right. Among my favourites from years gone by there is represantatives from all branches (actually i´ve never listened to a tube/mosfet hybrid that has been really satisfying).
Preamps- the pearl phono is really good, so is the Kaneda and copies, but close to impossible to get to stay balanced( there is an even better design in Toshibas small signal transistor handbook). So now i´m gonna put new logs in the fireplace- Nuvistors!! The best and funniest way to make a really good preamp- maybe a matter to dissagree about- wich will keep the discussion ongoing.
