Hi!
I recently finished a 10W version of Henrik/Nelson's XSOZ.
Many thanks Nelson and Henrik for your wonderful designs!
As the folloving pictures will reveal, I think this must be the (next) smallest SOZ ever buildt. High WAF was a deciding factor for me. The penalty for this is a firebreathing hot amp that runs all of the components on its limits, I doubt that it will last very long in its present condition, but tweaking/tuning will take care of that (I will have to scale it down a little power-wise).
The chassis:
Hybrid between Schroff Euro-Pac components and my own.

Thank you Henrik!
I will be back later aswell. Tonight my X-amps are will be put through their paces.
Here's a pic of the XBZLS and the XSOZ together.
As to the sound I will simply quote Nelson:
"The Son Of Zen has a wondeful sound, very direct and clear, without the electronic veil imposed by complex feedback circuits."
(And that's before you X it) 😉

Mads! You're my hero : )
what a beauty! It is amazing the jump in dissipation from
5 watts to 10 watts. At 5 watts my SOZ runs almost cool on the
heatsinks i'm using... but at 10 watts, yikes!
X-SOZ = coolest Pass amp to date

Could you please mail me the schematics used for your amp, including values for trafos and so on.
Im working on a collection of schematics of actually made zen series amps to post on a wiki page.

Woooohhw
How hot does your amplifier run?????
Mad K `s Son Of Zen runs pretty hot. You better put on some gloves on when you turn this amp off.😀
We have been listening to the amp for a few hours now. So what do we think so far..............................
Compared to Mad K`s gainclone this hot beast is quite another cup of tea. For me, the most impressing differrence is the musicallity of the X SON OF ZEN.
IMHO MAD K`s gainclone sounds a bit "thin"/distorted? compared to the X SOZ??! The music has more "layers" with this amp compared with the gainclone.

Mad K, you did it again.
First of all, mad props to you. Your chassis work and layout is, as always, a precise and thorough job.
So, what's it like? How does it sound? Well, my reference in the DIY world is Mad K's old SOZ as well as his later GC's, and also heaps of commercial amps. I'll compare the sound to that of the GCs, as they are what I've spent most time listening to.
The main difference IMHO is the capability do deliver the complete sound stage (as long as you don't drive it too hard). The push-pull GCs come short in terms of bass sound. The bass is "richer", and much more vivid. Last, but certainly not least, it never lags. Even though the GC's are very good amps, they can't match the power of the XSOZ.
It's time for more juice. Logging off...

to me the SOZ has the blackest of blacks... crystal clear sound.
i'm currently building a X-BOSOZ... i didn't want to modify my
BZLS 'cause it's running the Aleph 2's, and i like the sound of them
the way they are 😉
can't wait to pair the X-BOSOZ to the X-SOZ - mostly because
Henriek says it'll sound better being run by the X-BOSOZ.
Mads, could you give some close up pics of the wiring around
your fets?
thanks,
m.

Quoting Mad K (who's just about had his last drink tonight 😉):
Today, I've found a new belief. It does not involve Jesus.
Btw, I didn't know Dire Straits could sound like this...

Un fortunately I haven´t heard my new XSOZ because my midrange speakers is beeing reconed in England at the moment. 😡
I have attached my setup in PDF.

Aww! I tried to post a picture for you moe29, but havarden had been logged on using my computer last night, and he is still in moderation.. So, there will be a post seemingly coming from havarden, but is in reality coming from me..

Sorry, I will not do this, because the amp is almost burning up in its present condition... It is simply waaaay to hot, so maybe later when I get things under control 😉
