Not the best idea for best resolution a high quality preamplifier is better in dynamics as well as resolution The Meitner 3 is pretty good but put against my
LTA Micro Z- OTL preamp. It came up short on several levels ,buy a much better dac that would be the first thing . You never mentioned your Amplifier ,
a New hot Dac you can get for around $5500 is the New Merason R dac, Terminator-15, or Holosprings May , , all dacs require good digital cables and power cord. , to get the most out of them .
