No ground and Balanced Combination

(1/2) > >>

dflee:
I've got an older home that has solid copper wire (vs strand). This stuff is incredibly stiff with just hot and neutral.
Does this effect the audio system such that thinking about trying balanced is not worth it.The dac (MF M1), pre (Accuphase C11) and amp (MF M6sPRX) all seem to be truly balanced.

Thanks
Don

rollo:
  Still grounded though Neutral.

It has hardly any affect in a home stereo. Most of them might be positive.

Personally, I would not waste my time with balanced as I can completely dial out any 60hz hum, if any is present.

Second, any imbalance in a "balanced" tranny or circuitry causes its own problems 

Third, the balance created deteriorates with time, especially due to capacitors, transistors integrated chips, and other SS parts etc.

Fourth, I have already demonstrated a near perfect SE design amp, and perfect SE preamplifier design

Fifth, the cost of balanced designs

Of course there are other SE designs that might benefit from being balanced.

As far as grounds, pin 1s; If two components use a pin 1, there will be left and right channel musical signal return 
through the pin 1 wires from component to component. This will mix both left adn right channels together to some extent. Companies should design to minimize mixing under such conditions. Virtually none do.

With that said, using just one component with pin 1 ground wire will basically prevent L&R mixing from occurring. Just make sure when eliminating pin1 from a component that it is designed to be totally safe under that condition.

I would always connect the interconnects before plugging in the power cords, just to be safe.

cheers

I agree that I think balanced is a waste. But as far as the ground it really doesn't matter for that factor in home audio.
