SA-1000 Audiophile Tube Preamplifier Audio HiFi Electric

The audiophile electronic tube preamplifier is a high-end audio equipment that combines vintage and modern technology. It takes audiophile-grade electronic tubes as its core and realizes the delicate restoration of audio signals through the superior rendering of electronic tube tones and low-distortion signal processing. It is equipped with multi-channel audio input and output interfaces, using separate circuit designs to ensure the purity and stability of signal transmission. Users can customize the adjustment according to their preference and the characteristics of the audio system with the help of the treble and bass adjustment function to achieve HiFi level sound quality performance.



Features:

【Superior Audio Processing and Restoration Technology】: The SA-1000 preamplifier is designed with an all-aluminum enclosure and built-in audiophile-grade 6H3N tubes, integrating a tube preamplifier and a lossless audio switcher into a single unit to achieve low-distortion, highly restored audio signal processing. The circuit is an independent design, easily solving the insufficient line output, sound conversion noise, and other problems to ensure a pure, real audio output experience.

【Comprehensive Audio Input and Output Configuration】: Equipped with 4 sets of RCA audio input interfaces, it can access various audio source devices such as cellphones, computers, players, CDs, etc., and is connected to audio devices such as amplifiers, active speakers, etc. through 2 sets of RCA audio output interfaces to realize free switching and selection, ensuring that each link achieves a HiFi level of sound quality performance.

【Professional Sound Quality Optimization Function】: Built-in 5532 operational amplifier chip, with volumes adjustment and high and low sound adjustment functions, you can customize it according to the parameters of different audio equipment to achieve the HiFi sound effect. The earphone section also adopts a 5532 chip, which can easily handle various impedance headphones on the market, providing clear and delicate, dynamic, and powerful sound performance, bringing you a feast for your ears.

【Premium Material and Long Durability】: The SA-1000 has a stylish design that blends aluminum alloy housing, vintage tube, and VU table elements. It is compact in size and easy to place on a desktop. At the same time, the use of gold-plated RCA lotus sockets ensures low impedance and high conductivity for signal transmission and higher durability.

【Highly Integrated and System Compatibility】: As a comprehensive audio device that combines the functions of a HIFI bilevel preamplifier, lossless audio switcher and audiophile earphone, SA-1000 is the core component for building a desktop HiFi audio system, which not only provides a rich interface of 4 simultaneous inputs and 2 outputs, but also ensures that signals are independently isolated from one another and do not interfere with each other. Whether in home entertainment or professional scenarios, it can show superior audio processing capabilities and system compatibility.
