Why doesn't Musical Fidelity offer balanced output

To answer some of you, i would like balanced because all of my cabling is xlr. also, some of gear does sound better using the xlr connections vs the rca. i dont know why.

I would disagree with Bob_reynolds in that it DOES matter if the unit is fully balanced or not. Why have pseudo balanced connections if the signal is to go through a bunch of bandaid phase-splitter and summing-amp stages for the sake of achieving "balanced" components. Either do it right all the way or don't bother at all. And yes, the RCA connector is a pain and a joke.

As for balanced connections making a difference on components that are truly balanced and that have both XLR and RCA connections, with the Aesthetix Io into the Aesthetix Callisto, the XLR cable here significantly outperforms the same model RCA cable in the context of portrayal of space alone. This is one example where the difference is enough to make anyone believe they were not the same components when driven by the same model cable.

The value for the CMRR only exists if we do not bandaid the signal path to achieve complimentary phases from a signal that started out as single-ended. If much degradation is done to the signal to create these 2 phases, there is likely more to be lost than any benefits to be had through the reduction of noise due to running a complimentary signal.

As for an engineering argument here, there are far too many implementations in a circuit design as well as cable design to botch up any number of cases here. If someone is gung-ho over the benefits of CMRR through balanced design, do it correctly throughout or don't do it at all. Attempting to reduce the noise floor does not guarantee you will not cause greater destruction to the signal in the process.

I ran with truly balanced ARC and BAT products for nearly a decade from phono cartridge and DAC to the amplifiers and when I switched to running a 10m Purist Dominus RCA IC from the Aesthetix Callisto to CAT JL-3 amps, ironically, I had more resolution than before. And therefore it was not the toplogy but rather the implementation.
