I guess I'm just not sure how you're allocating budget with the 830 monoblocks. They're like $8k, right? If you are spending that much on amps, and $5k on speakers, spending like $2000 or so on a good DAC seems like a logical next step, unless you don't listening to digital music. There are so many great options. What do I have? I'm not sure why it matters, but my current list of DACs (in order of most used): dCS Rossini+Clock, dCS Bartok, Chord Hugo 2, RME ADI-2, Lynx Aurora (n), Mytek Manhattan 2, Mytek Brooklyn DAC+, Theta Casablanca V.
