LUMIN X1 utilizing Leedh Processing going direct to amp is very, very good. I also have a Mola Mola Makua preamp with DAC. In initial testing, I slightly preferred to utilize the Makua preamp volume control vs the Leedh Processing user optional volume control feature for the X1, but I have not revisited testing that. I really llke Leedh and applaud LUMIN for including it at no extra charge for the X1. The newly released T3, as well as P1, and prior T2 also include Leedh. Early reviews of the T3 are positive and list price in US is just below $5,000.
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?
