• Hand-made construction of a heavy-gauge, fully-vented steel chassis with a five coat finish, each coat hand-rubbed and polished, holding the finest point-to-point wiring, using workmanship that is normally only available at the highest price.
• Elegant style, heavy-metal remote controls for all EVO Tube Preamplifiers.
• Premium parts that include separate toroidal and EI transformers for left and right channel power supply; wide bandwidth for great bass and extended highs; ceramic tube sockets; motorized ALPS volume control; Nichicon and DuRoch capacitors; 5AR4 tube-rectifier-circuitry; gold-plated panel mounted RCA and XLR input and output jacks.
• A 100% shielded Phono chassis for mounting our optional MM PhonoLogue circuit.
• SoftStart™ circuit for extended life of sensitive components, plus a reduced chance of tube failure from thermal shock.
• All PrimaLuna power transformers include the  PTP™ (Power Transformer Protection) circuit. When the power transformer overheats due to environmental circumstances, overloading or some problem in the unit, an internal thermal switch breaks the primary, allowing the unit to cool down before harm is done. After it’s cooled, contact is restored and if nothing is broken, the preamp will repower and function properly.
• LIVE side of the AC input connector indicated by aluminium color screw.
• A minimum of 4 line-level inputs (RCA or XLR), depending on the model you own.
• 1 pair of RCA Tape Out, 2 pairs pre-out (RCA or XLR), depending on the model you own.
