Matt,
well, I see you have opened the floodgates to the Boulder 2150 server/dac at $65k list price. so maybe you need to now hear an $84.5k dac/passive analog preamp.....the MSB Select II.
http://www.msbtechnology.com/dacs/select-features/
standard with a single powerbase and 77 femto clock. I just upgraded to the second powerbase and mine has the 33 Femto clock.
after hearing the Select II at a show a few years back I could not escape that reference in my head listening to other dacs in my system, and eventually it wore down my defenses and I acquired one.
I hope you can try one at some point. even if it's just at a show. that's the only place I heard one (3 different times) until I owned one. it's really on another performance level beyond other dacs I've had in my system (Trinity, Aqua Formula, Nagra HD, Lampi GG) or at shows and more in very good vinyl playback performance territory, and includes an exceptional passive analog preamp and analog inputs, modularity for future proofing, and a 10 year warranty and 'upgrade at retail difference' program that keeps it cutting edge relevant for a decade. when 'some' here look back 10 years and add up their digital investments + preamp investments, this starts to pencil.
no worries if some get their panties in a bunch over the price, comes with the territory. I just had to throw this idea into the hat, now that the hat is so much bigger.
cheers,
Mike
