I have a Wadia 321 with the ESS Sabre volume implementation. It sounds very analytical vs running it through my Rogue with Mullard valves. But I am a fan of hybrid setups (Tubes & SS).
The Wadia 321 is a good DAC and can be had for around $1k but it has a sizable footprint. Has a bunch of inputs (coax,digital,USB). 321di will process DSD.
Wadia gone now but 3rd party support does exist
