Balanced to RCA interconnect--is it beneficial?


Audible Illusions 2D preamp with RCA (only) outputs into a
Sumo Andromeda III amp with balanced and RCA inputs. Would there be any benefit (sonically) to go from Balanced to RCA,
or just stay with my RCA to RCA.
I would guess there is no benefit, but I really have no idea, thats why I'm asking this forum of Knowledge...Seriously.

Thanks, Roger

Dr. Richard Bews:

Balanced operation has advantages in environments of high noise or where cables have to be very long. Studios are a good example. The domestic environment normally doesn’t require balanced operation from a technical viewpoint. Balanced operation came about, because certain US manufacturers could give some technical bullshit to sell their amplifiers!

Balanced operation invariably adds complication, which can lead to problems, so why make the life of an amplifier more difficult than it needs to be?

It’s difficult to make a simple amplifier sound really good, so doubling the amount of circuitry (as often happens in balanced amplifiers) just makes it more difficult. When (our) amplifiers interface with amplifiers with balanced inputs or outputs, we prefer to use specially designed transformers to convert between single ended and balanced operation. This is simple, but does put demands on the circuitry and the design of the transformer.
