Balanced topology imposes twice the circuitry into the signal path. It is not quite that simple. There are many was to implement either one so it all depends on the design. There are very complex SE circuits and very simple balanced ones. Since a differential amplifier has more gain than a comparable SE circuit you could easily end up with less stages and less circuitry. In any case the amount of circuitry is not a design criteria. If additional circuitry leads to better sound then its a good thing. |

audio, especially 2 channel systems with analog being the primary
source will rarely benefit from balanced connections. Adding balanced
operation in this scenario will only add more circuitry with no real
benefit and likely have deleterious effects. One should attempt to have
a full-featured preamplifier that includes a well designed phono stage.
This approach has significant advantages. The installation is much
simpler, the cabling requirements are simpler as this approach has a
concentrated purpose. Avoiding ground loops is generally not a
problem with this approach and cable lengths can be kept to a very
reasonable length. Plus the number of cables is minimized ... It's rather vague to state "analog being the primary
source"
in your premise. If you're referring to LP, I think you couldn't be more mistaken.
A phono cartridge is an inherently balanced source. If you feed it to a truly balanced (differential) phono preamplifier, you'll add gain where you need it most, and reject noise and interference where you need to most. And you'll avoid having the cable influence the signal. Again, that's where you need it most.
To state that "
balanced
operation in this scenario will only add more circuitry with no real
benefit" is absurd. Yes, differential amplifiers add more circuitry - but there are multiple real, measurable benefits - especially when a turntable is the source.

I like the way you write.

Well I can Say the Atma-Sphere amplifiers with the Classic Audio Loudspeakers sounds Sublime with Clarity, Musicality, Frightening Dynamics, Smoothness its just plain Truth Full!

I learn more from Ralphs Writing than i ever have reading other professional designers post here at Audiogon!!!
Stuff justs clicks so much faster the way he explains it.
