Shadorne - Eliminating ground-loops is a good idea. Few audiophiles do it. However, balanced alone does not get you galvanic isolation unless you have transformer coupling in the components. You can get it with this:

Also, it is good to understand that most preamps and DACs, including my own, that generate balanced outputs using solid-state output stage are not really technically balanced because it is impossible for the + and - signals to be exactly the same amplitude, particularly over a wide range of signal amplitudes. The only way to get this is using a signal transformer. Once you do this, the amplifier tends to sound a lot better, so ther are more benefits to a transformer than just isolation.
Jitter can usually be reduced more by using a reclocker, even though the DAC resamples and reclocks.
knownothing - You may get to hear my Overdrive SX at future shows, but I'm not doing shows much anymore. It may be in another companies room. I am looking to do a headphone amp next, so I may just be in the headphone area at some shows now.
