Default Why balanced?

I don't know much about electronics.
But if i'm not mistaken the aleph amps are class A single ended designs.
Why should the preamp or the AXO be balanced?
Is there a real advantage there?
I have no experience with balanced designs, i have never used one in my system.
What are the sonic benefits of balanced operation?

Thanks,

Nick

balanced interconnects minimise hum and noise pickup and if the signal path is balanced back to the source, also minimise timing noise and other unwanted spurious signals by virtue of differential cancellation....

Default Audiofreak,

I understand, but isn't there also a negative effect due to the extra active devices added to the circuit?

Thanks,

Nick

as far as line level goes, the gains outway the negative effects which equate to practically zero in this case. Make sure you do not confuse balanced with push/pull operation, I generally prefer balanced single ended circuits.

Some information, on what appears to be the Claw jr, extracted from the XVR1 ELECTRONIC CROSSOVER NETWORK OWNERS MANUAL:

Real Project #2
"This is a much more complex system. It has twin 21 inch subwoofers mounted in a 12 foot long transmission line, a 12 inch woofer for midbass, a 5 inch midrange, and a ribbon tweeter. This system will be quad-amped."

"And there we have it, a quad-amped loudspeaker with a response +-5 dB from about 18 Hz to 40,000 Hz."

Wow! My appartment does not even have a ceiling 12' high

A great manual by the way - highly informative about crossovers - a must read! A big thanks yet again to 'the one and only' for making all this information freely available.

This is not Claw Jr., but rather an interim woofer project
named "El Pipe-O" to be released shortly.
