I still own an Antelope Zodiac Gold and IMO it sounds wonderful and is brilliantly engineered. I use it as a passive preamp (via the volume control on the analog side) in my all digital rig. Having said that, however, it is really more DAC than I require (I don't play files at higher res than 192k) and it's a little on the expensive side.
I have been looking at the new Teac UD-501 - it sounds great and is well-made, but does not offer volume/gain controls and no remote. It's the same same for the Schiit Gungnir. I have also heard the M2Tech Joplin; very nice, but I do not find it to be the sonic equal of the Zodiac Gold. The specs for the Empirical Audio Overdrive SE looks great, but it seems stupidly expensive for what it is.
