- Generous inputs (USB, optical, coax, plus an RCA analog input) and at least 2,000 mW balanced into 32 ohms
- No Bluetooth on the standard model and no built-in EQ or tone controls
- Plain, no-frills feature set with no remote or on-screen menus
iFi ZEN DAC 3
Buy itA warm, characterful DAC/amp with a proper analog bass switch, for people who don't want clinical neutrality.
- Warm, musical Burr-Brown sound that flatters bright headphones and everyday tracks
- Analog XBass boost and PowerMatch gain add genuinely useful tuning without menus
- Balanced 4.4mm and single-ended outputs in a compact, distinctive chassis
