Totaldac dac as a dac + preamp

I was thinking of purchasing this after I buy my power amplifier. Would it be a good match with a mcintosh 462 amp? What model would be the best to get? He has many different versions. It seems to make the most sense to get the balanced version though. It is 13500 euro I believe! But if the preamp portion of it is any good the value does seem to be there, no?

It any owners could chime in with their thoughts, and how they use their total dacs, and what model they have that would be much appreciated!
