Esoteric SA-50 SACD player, Is it for me?

I am currently using a Mark Levinson 39, which I like.

But I am interested in trying High Resolution digital.

The SA-50 seems to offer may features that I am looking for, balanced variable output and digital inputs for PC audio and a SqueezeBox, USB , etc.

I listen to classical only, use ML331 amp direct ,no preamp.
Speakers, Ariel 10T.

Does anyone know how the variable output on the SA-10 is implemented? Analog like the ML or digitally?

Would this be a good choice? Are there other units I should consider?

Thanks for any input.
