Original box and packaging included.

Fully discrete Class AB topology ensures smooth, detailed sound and incredibly natural imaging while maintaining efficient performance
Oversized toroidal power transformer with dual secondary windings and independent power storage capacitors for each channel provides plenty of real power for demanding program material, with virtually unlimited power reserves, and vanishingly low crosstalk.
Top quality parts and construction throughout for years of reliable service.
Stealth styling, featuring a faceted face plate milled from solid 1" billet aluminum.
Front panel LEDs continuously display the SA-250's status and indicate fault conditions.
Stealth mode lets you disable the status LEDs for discreet operation.
Professional quality 3RU chassis provides strength and durability.
Independent metal toggle switches allow you to separately configure each channel to use the balanced or unbalanced input for maximum flexibility.
Independent gain selection for each channel lets you perfectly match the SA-250 to a wide variety of front end equipment.
Gold plated five-way speaker binding posts with clear shields allow you to use a wide range of speaker cables with bare wires, lugs, or banana plugs.
Solid machined gold-plated unbalanced RCA input connectors provide a tough, reliable connection with a wide variety of audio interconnects.
Combination 1/4" and XLR balanced inputs provide compatibility with a wide variety of audiophile interconnects and standard studio connections.
Individual ground lift switches allow you to independently lift the ground connection of the balanced input on each channel to solve tricky hum problems and eliminate ground loops.
Remote trigger input and output allow the SA-250 to be turned on by trigger-enabled equipment, and to activate other trigger-enabled equipment.
Audiophile-grade fault protection is entirely transparent under normal conditions, yet protects the amp and your other equipment from all common fault conditions.
Universal AC line voltage operation; 115 VAC or 230 VAC (user selectable).
Standard IEC power inlet fits all standard and audiophile IEC power cables.
