So you think that the difference in sound when you A/B them is because of the inversion? If that's true, we should all start adding inversion switches on our DIY equipment.

What I was wondering about was the BOZ adding "pleasing artifacts" to the signal, as some contend.

That is a tough call,I can change the sound of the BOZ according to what brand of coupling capacitor i use.The gain stage itself sounds very clean while not having that "etched" sound which to me causes listening fatigue with long listening sessions.

In a purely philosophical vein:
I'm always curious when I hear comments such as 'pleasing artifacts' or one classic that was phrased contemptuously to me,"it sounds better than music"...why is it that people react with suspicion--and sometimes with hostility--when things sound good? Is there some deep-seated need in audiophiles to 'suffer for their art' by listening to equipment that sounds somehow less pleasing?

just a thought but you could just hang a couple of BUF-634 or BUF04 off the output and add maybe an audio express jung regulator board for a small internal headphone amp that would take up little space in the BOZ.The Szekeres is definately a two box solution when you consider the heat sinking and power supply requirements

Grey,
I agree, if they are "pleasing" artifacts, isn't that what we want? I am reminded of 2 things: an editorial somewhere once that said, "that warm sound of tubes is actually distortion"; and the "Tubehead" preamp that allowed a mix of op-amp and deliberately distorted tube stages. You could adjust the mix, which I bet would be different for different music.
That's why I asked about the difference in switching in the BOZ stage.

I'm sure I have it. If I get the chance, I'll get it out early next week, unless someone can link-it for the man.

I believe they are the ones published in Audio Amateur (#3, 1995). If so, you can buy circuit boards:

I remember there have been updates to the original article; some builders had oscillation problems. Best to get an updated version of the schematics.
