Simple source switching and routing: Four input channels let you connect multiple sources at once; two outputs make it easy to feed a power amplifier and a recorder or a second amplifier/zone without constant plugging and unplugging. Clean integration into existing systems: Acts as a linelevel control stage so you can preserve signal quality while gaining tonal control and routing flexibility. Compact and attractive finish: Available in Black (SA1000 Black) with an optional Champaign Gold aesthetic for systems where appearance matters. Core features and attributes Functionality: Stereo preamplifier with tube amplification stage for tonal shaping plus linelevel input switching and dual output routing. I/O: 4 selectable inputs and 2 line outputs provide straightforward multisource management and simultaneous output options. Compatibility: Designed to work with standard linelevel devices and system components such as CD players, DACs, streamers, tuners, tape decks, power amplifiers, and active speakers. Performance: Delivers tubestyle warmth and musicality while serving as the control hub for volume and source selection in HiFi systems. Size and build: Compact footprint suitable for desktop or rack shelf placement; designed for reliable daytoday use in a home audio environment. Finish and model: Offered in Black (SA1000 Black) and also presented in a Champaign Gold variant for aesthetic matching with other equipment. Practical use cases Home stereo upgrade: Use the SA1000 as the central preamplifier in a livingroom HiFi system to switch between a CD player, DAC/streamer, and auxiliary sources while adding tube warmth before feeding a power amplifier. Twozone or recording setup: Run one output to your main power amplifier and a second output to a recorder, headphone amp, or secondary amplifier for a second listening zone or simultaneous recording. Desktop or small studio monitoring: Connect multiple linelevel sources and route to active monitors while benefiting from tube coloration for critical listening or creative reference. Who this is for Audiophiles seeking the tonal benefits of tubes without redesigning their entire system. Listeners who want a simple, reliable preamplifier to manage several sources and feed one or two outputs. Users who value both sonic character and practical routing in a compact, visually appealing unit. Setup and integration tips Place the preamplifier on a stable, vibration surface with adequate airflow for tube components. Connect your sources to the available inputs and route the primary output to your power amplifier; use the second output for recording or a secondary amplifier. Match levels and impedance according to your downstream components for performance.
