DACs that do well without a preamp


I am looking for a DAC to feed my DNA-1 gold power amp directly, streaming Qobuz or Tidal from a Bluesound Vault. Budget is $1-2K; would consider used, if worthwhile. Current contenders are Benchmark 3 HGC, Brooklyn DAC+, Gustard x26 pro, Holo Spring 3, Musetec 004 and Pontus ii. Looking for clean, detailed, uncolored sound that "lifts the veil". What are the qualities I should look for to drive an amp well, without a pre?

PS Audio DirectStream works well. I go direct in my secondary system and through a preamp in the main sys.

@soix  a DAC that uses transistors, or tubes for the output stage is not passive, it may not have gain like a preamp, but it's still has an active device for the output.

While that may be true, many of them do not provide enough gain to fully drive an amplifier, which is the primary issue in many cases.  Active or not.

Running a dac direct especially at $2k not good even high end it’s sonically better sounding with a quality preamp section . In a preamp Alps pots, or Bourne are $25 and loss of detail is for sure ,that’s why I avoid any integratedthat has these,a silver round attenuator is what to look for. ,a horrible cheap way out  but used by 70% of the industry it seems , a good resistor ladder shunt type  ,relay control or linear Type  , are Night and day better and  in higher end equipment.
