I purchased a used AQ Vodka Ethernet and compared it with my then current (no pun intended) Wireworld Starlight 8. The Vodka clearly was the winner in my rig. More full-bodied and deeper, more taut bass, better natural vocals, and the piano test definitely tipped the Vodka in its favor. Starlight 8 sounded relatively thin. It is excellent for the price, but Vodka is a notch above.
Want to try the EtherRegen device when I am familiar with the Vodka.
Higher priced Tidal, PS Audio DSD w/Bridge II, to VTL 7.5iii preamp to Krell FPB 300 cx (recapped) to Magico A3's. Musically, life is sweet. Neal
