Why Single-Ended?
Thank you Ralph for explanation about third harmonics. I understand that advantage of the fully balanced configuration is removal of second harmonic to better hear the third one (that you try to lower?). As for the balanced cable - yes it can run ... 
Why Single-Ended?
The way balanced line eliminates cable artifacts is twofold. First, ground is ignored, so the shield is not part of the sound (nor the is noise to which its exposed; in a single-ended system the shield is part of the signal path).You cannot elim... 
Why Single-Ended?
Thank you Charles.  While not opposing any topology I think less is more.   As electrical noise is concerned, home environment is in most cases benign.  I argue to learn/understand and I have, especially from Al and Ralph.  This forum is great. 
Why Single-Ended?
This statement is false. A fully differential amplifier does not have twice the parts and is not nearly two amps inside! This is a very popular myth.  I don't know your designs, but usually output stage, at least in SS amp has to be doubled, as... 
Why Single-Ended?
Thanks Al,  Third harmonic, that supposed to be euphonic, will be the same in fully balanced or single ended design.  Removal of the even harmonics cannot make amplifier sound "warmer".  It is achieved by reducing higher order odd harmonics produc... 
Why Single-Ended?
Converting single ended - balanced - single ended using transformers, makes sense if you have a lot of electrical noise and connection is long. Otherwise transformers won’t add anything positive to sound. They will introduce some low frequency dis... 
Why Single-Ended?
Al, since I don’t see removal of even harmonics (while leaving odd harmonics intact) as an advantage, then the only thing that speaks for Fully balanced amp is better noise rejection in comparison to amp with True balanced input. Balanced input of... 
Why Single-Ended?
Phase has to be inverted somewhere, either for TRUE balanced (XLR cable) or FULLY balanced design.  It involves extra circuitry that does not make sound more transparent.  For short connection, in electrically quiet environment, single ended desig... 
Do caps deteriorate with time even if an amp is not being used?
Electrolytic caps loose rated breakdown voltage and also dry out.  They loose rated breakdown voltage because electrolyte "eats out" dielectric - aluminum oxide (presence of voltage rebuilds this layer).  They dry out - especially when hot.  Each ... 
They Almost Never Quote A Price , Why?
It is pretty much like restaurant with no prices on the menu - if you have to ask you cannot afford it.

It does. 
Bi-wires links for speakers ?
Highs - sounded more extended. First time I installed them in Paradigm Studio/60 v2 speakers that came with stock bent plate jumpers. Now I have them with Hyperion HPS-938 that came with long insulated wire jumpers. These speakers are three way wi... 
Bi-wires links for speakers ?
itzhak1969, I use Audioquest 4" jumpers.  They're made of high purity AQ copper and come either silver or gold plated.  I use gold plated version.  Big improvement over stock thin-plate links.https://www.amazon.com/SET-4-GOLD-BIWIRE-JUMPERS/dp/B00...

Voltage source vs. current source amplifiers
Ideal voltage source provides voltage that is independent of the load.Power delivered will be inversely proportional to load impedance.Ideal current source provides current that is independent of the load.Power delivered will be proportional to lo...
