About this item
- RETURN OF THE CLASSICThe A1S is a pure Class A power amplifier delivering 20W+20W (8Ω), 25W+25W (4Ω) output power. Reference classic circuit, with its characteristically British tonal signature — delicate, warm, and melodiously smooth — it offers a captivating listening experience ideal for music enthusiasts.
- LARGE CAPACITY MAIN FILTER ARRAYIt adopts four 18000μF/35V filter capacitors from Nippon Chemical's Black Diamond per channel, with a total filtering capacity of up to 144000μF.The charging and discharging speed is extremely fast, which can make the dynamic response of the entire machine more rapid and the penetration deeper.
- EQUIPPED WITH OMRON RELAYTo prevent switch on/off shocks and DC output protection, silver alloy contacts have a long service life and stable performance, providing protection for the equipment.
- ANSEM POWER TRANSISTORthe left and right channels employs a pair of Ansem MJL21193/MJL21194 power transistors, frequently utilized in Swiss luxury high-end audio amplifiers. These transistors perform extremely well in terms of sound clarity, layering and detail resolution. As a set of audio-grade power transistors that enable fatigue-free listening for extended periods, they are ideally suited for AB-class and A-class amplifiers, boasting exceptional linearity.
- LARGE TOROIDAL TRANSFORMERThe power amplifier's strong motivation originates from the toroidal transformer, which has a strong power reserve. It is like the giant A-core uninterrupted transformer in a car's engine, providing a continuous source of energy for power amplification!
