Truely Balanced Pre Amps

A 'fully balanced' preamp will not have the signal appear anywhere in the circuit in single-ended mode, except at an input. So all the switching, the volume control, EQ is all in the balanced domain.

So how many drop out when this rule is applied?

The advantage is lower noise and lower distortion, to the point that less gain stages can be employed.

There is less than double the parts so the cost ought to be less than double too. And yes, there is a fully differential way to do this.

Cary slp 2002 and I think the slp 03 too (fully balanced). the Cary gear has the best HT bypass I've seen too.

kw.....

The Audio Horizons, TP 2.0 has balanced circuitry.
