PrimaLuna is a Dutch-founded, family-run hi-fi company dedicated exclusively to vacuum-tube electronics.  Since 2003 their integrated amplifiers, power amps, preamps and DACs have become modern classics for three big reasons:

1. True-tube sound without the headaches – PrimaLuna’s patented Adaptive AutoBias constantly monitors each output tube, so you get the seductive warmth, holographic imaging and mid-band “glow” of Class-A/B valves without manual biasing, matched quad requirements or runaway-tube failures.
2. Bullet-proof, over-built parts – Point-to-point wiring, custom wide-bandwidth output transformers, PrimaLuna’s “AC Offset Killer” power filtration and generously-sized power supplies give every model wide dynamic swings and a vanishingly low noise floor.
3. Upgrade-friendly value – By manufacturing in a dedicated Chinese facility but specifying European/Japanese parts (ALPS, Nichicon, Takman, Rubycon, C-Core transformers) they deliver heirloom build quality at prices that rival solid-state gear.  The circuit tolerates EL34, KT88, KT120 and KT150 output tubes, so owners can roll to taste.

The result is gear that marries old-school valve magic with modern reliability and plug-and-play simplicity—equally at home driving efficient high-end speakers or giving vintage vinyl rigs the rich, musical presentation audiophiles crave.
