you got it all wrong mm, all wrong.

Who purchased what rights to what patent? Pass' super symmentry is a furthur enhancement of a fully differentially balanced circuit from input to output which is always better than a unbalanced input and output.

What I see is twice the circuitry (in the patent) than through an unbalanced circuit. I would have to weigh unbalanced (vs) balanced with an op-amp (vs) twice the circuitly as in this patent. The minimalist would probably head towards unbalanced ....

True there is a full duplication of the circuitry for a fully balanced design but each phase or (half)of the signal is only seeing one half of that circuitry.

It switches twice on each half cycle though so crossover distortion happens on each 90 degrees of the waveform rather than every 180.

I didn't intend to step on anyones brand envy here so I'll step down.

Since both halves of the signal are equal in level but opposite in phase any noise or distortion common to them will be effectively cancelled.

I asssume this is directed at someone else as I never made any suggestion as to brand loyalty.However my comments would be applicable regardless of brand of manufacture.

I am assuming my gear is balanced, but maybe it isn't,

Your BDA1 has a true fully balanced output but in all probability the Cambridge and Sony use the invertor/summer dirived method of sending and recieving balanced signals.

it would be nice if there was some way to determine it.

In most cases the manufacturor will state a product is fully balanced.If they went to the trouble of engineering such a product they believe it has advantages thus will likely make such claims for it.

Im am using all balanced connections,at least they make solid connections between pieces.

Good point,the XLR IMO is a much superior mechanical connector vs the RCA.

No brand envy whatsoever, you're just not fully understanding the patent and what it can do to make the signal more pure, that's all.

Balanced is another industry "buzz" word that can be interpreted a few ways. Unfortunately a few of those ways aren't any better/different than single ended. Super Symmetry is different and is truly balanced which is always a plus generally speaking.

I am out of this one as well, no harm, no foul.

Those that go balanced convince themselves that it's the best route, in one way shape or form. I could honestly care less and will still have a smoking hot sounding rig.

My system is balanced end-to-end. My main motivation for going this route is for headphone listening. If you've ever heard what a balanced headphone amp and headphones converted to balanced operation can do, you'd be sold. My headphone amp is also my pre-amp, so I used the XLR connections into my Krell to power my SDA's as well.

I've heard and owned multiple balanced systems and it still doesn't factor into my audio life enough to drive hard and always do it. I've found that once some go balanced, all of a sudden, those that still enjoy un-balanced or just don't know....become less cool for some reason. That's not in every case but it's happened on here, for whatever reason.

Hey, audio is all encompassing when it comes to your beliefs. I just hope I get to hear some of these rigs at some point down the road With all the cool gear involnved....I'm late to the party.

Well, as they say; RTFM, or in this case, RTFWeb Site.

"The Azur 840E makes room for eight inputs, two of which have both fully balanced (XLR) and unbalanced connections"

For the 840W they have this,

" The second generation Class XD is now complemented by a new output stage carefully adjusted to integrate with this novel technology, revised balanced inputs for lower distortion and noise."

Since they designed the two to work together I suspect it is also fully balanced, or if not, still providing the same benefit.

Anyway, whether everything is fully balanced or not, I love this setup now. It is dead quiet at high volume levels, and, especially after all the cable upgrades and vibration tweaks, it sounds great.

I'm convince,that (XLR) is the way to go. glad I stated this topic. Well, you got the pros and the cons.
