Shure I will share my expirience from the CCS tests.
By the way, with what preamp do you intend to drive Your XSOZ?

Unless I have a better idea, I am going to drive it
with BOSOZ on page 21 of this thread.

I got the keel laying of XSOZV2.
The block dimension is 330mmx250mmx460mm (WxHxD).
Two transformers, total 600VA, are installed.
The heat sinks and two transformers look a bit oversized.
Yes, it is. I want to have flexibility with respect to the
current and power within certain range.
The show up of the inside wiring will come later,
no reason to make you disappointed now.

Looks really nice!
Tusen Tak!
I am going to use BOSOZ for the unbalaced-input and
balanced-output converter. Clearly no CMRR in this case.
I will however go for the X if it is effective to my converter.
What is your understanding? Effective? Any tip on this?

It looks nice, ... but why using so many interfaces? You have your fets on very thin piece of metal plate, then 2 angles (no champions in heat transfer either) and then heat sinks. Even if your sinks might be oversized, they'll do no good if the mosfets are too far from them. The circuit is so simple that I would be tempted to install the output devices directly on the heat sinks. Why not?😉
In this case the interface is OK.
Last night, I was cutting and drilling for the front and rear panels,
talking to myself: “Okay, I will beat the nice DIY designs of Peter Daniel,
I will... no, yes, no, yes...”
And, finished the panels, and found all sizes were made wrong.
I have to cut and drill all again tonight. Damn it!

The XBSOZ and the BSOZ is quite similar in diffrential behavier, so as a converter they do pritty much the same job.
The X will lover both distortion and outputimpedance.
Your XSOZ will need or benefit from the lower outputimedance provided by the XBSOZ.
If the XSOZ is driven with a signalsource wich is too low, then You will degrade the sonical quality of the amp, much worse than a little mismatch in the unbal to bal conversion.
If You want a perfect match in the conversion You could make a CCS at the tail of the BSOZ or XBSOZ, but what then happens to the sound is not qute clear to mee, my CCS tests in the comming weekend will at least tell me and mybe others too.

Okay, I am ready to go for the XBSOZ (probably yours) for the lower
distortion and for the lower output impedance. But, I am a bit confused
because you are saying simultaneously “good and bad” about the lower
output impedance. Do you mean the output impedance of XBSOZ is
to be neither too high nor too low? Would you clarify my question?

BOZ and things like that
Hi,
Can any help me with an explanation regarding all BOZ and XBOZ I want a list of all abbrevations I will search for single ended preamps and poweramps and it would be very nice to know what al this BOZ and company really is, as I'm a new to all this with single enden designs.

Original Nelson Pass designs:
Zen in difrent variations is just called Zen V1...n and is poweramps.
BOZ -> Bride of Zen, preamp for Zen.
SOZ -> Son Of Zen, balanced poweramp.
BSOZ or BOSOZ -> Bride of Son of Zen, preamp for SOZ.
Zen variations made on Diyaudi.com applying Nelsons patented Super Symmetry also called SuSy or X:
XSOZ -> Son Of Zen with Super Symmetry, balanced poweramp.
XBSOZ or XBOSOZ -> Bride of Son of Zen with Super Symmetry, preamp for XSOZ and SOZ.

You will proberly need a lower outputimpedance than the BSOZ provides, when You X it to XBSOZ You wil get that.
Another cause for confusion is the third (and original I suppose) name for BSOZ or BOSOZ which is the Balanced Zen Line Stage (or sometimes BLS).
