Matching fully balanced with unbalanced.

surfmuz OP
Hi, using Fully Balanced VS Unbalanced Preamp between Fully Balanced Source and Unbalanced Amp with all XLR Interconnections including amp.... Does it wort it or not ?

First off, you got to ascertain by looking at a circuit diagram of the input and output of the equipment in question.
To see if the balanced input or balanced output is "just a balanced opamp" used to give balanced output or inputs.
Because then the rest of the amplification circuit is probably SE (single ended).
If this is the case then the SE (single ended will sound better).

And if it’s is truly a "true balanced circuit throughout" from input to output with no opamps doing it, then it’s only got a noise advantage over SE if the interconnects are >5mts.

A very nice Classe DR** poweramp had just this opamp for it’s balanced inputs and the SE inputs did sound far better.

Cheers George

Sure simple, what comes out of 99.9% of hiend poweramps is SE (single-ended), the speaker terminals are + positive and negative is at ground potential.

Cheers George.
