1 in stock
The described audio amplifier is a high-performance, visually appealing, and well-built unit that combines a pre-amplifier and a power amplifier to overcome the limitations of traditional pre-main amplifiers.
Key features include:
Independent Pre-amp and Power Amp
The preamp and power sections are connected but can be used independently, with selectable inputs and a power meter for monitoring output voltage.
Advanced Power Output
A 5-parallel push-pull configuration with 10 output elements provides substantial power, even under low load. The drive stage employs a cascode push-pull circuit with MOS FETs for improved high-frequency performance and minimized distortion at low outputs.
DC Servo Method
This method stabilizes DC drift and eliminates harmful DC components, ensuring speaker protection.
Advanced Input Options
It features MM/MC phono inputs, with dedicated circuits for each cartridge type. The MM input uses a cascode bootstrap differential circuit for high input impedance, while the MC input focuses on S/N improvement with low-noise components.
Tone Control and Filtering
A high-quality addition-type filter tone control with an ON-OFF switch, subsonic filter for cutting ultra-low frequencies, and a loudness compensator for enhanced bass at low volume.
Speaker Outputs and Bi-Wiring
Equipped with two A + B speaker outputs, enabling bi-wiring for separating low and high-frequency sound networks.
Tone Control and Recording Functions
Tone control uses an addition-type filter, while a recording selector and copy switch allow for independent dubbing and recording while listening.
Remote Commander
Offers control over input sources, volume, and electronic relay switching for minimal sound quality degradation.
High-Quality Construction
The unit uses a low-leakage flux toroidal transformer and high-speed diodes for efficient power delivery. Relays are specially developed for audio equipment to minimize contact resistance and improve durability.
This amplifier delivers superb sound quality and versatility, making it ideal for audiophiles seeking both performance and aesthetics in their audio equipment.
