The A-17, a serious upgrade to the famous SV236, is a 2x 100W on 8Ω, 2x 200W on 4Ω integrated hybrid amplifier with the first 2x 10W biased in Class A. It comes with bass and treble controls, loudness control, tone defeat and soft start. The remote control selects the four inputs and adjusts volume. It features a classic pre-amplification stage with 3x 12AX7, followed by 1x 12AU7 as the cathode buffer, yielding its rich expansive sound, warm and smooth transients and vocals, vacuum tube and transistor precision high voltage rectification with a 6J4 rectifier tube, visible in the tube window at front panel, in the power supply circuit, solid state power output stage, JFET Class A current amplification, high-end MKP for audio use coupling capacitors, high fidelity bass and treble tone control with bypass option, no negative feedback on tone control circuit for natural expressions, Infrared full remote control, High-end JAPAN made huge ALPS motorized volume control, Gold plated speaker output posts and a Detachable IEC power cord system. Nevertheless of price level, inside of A-17 you will find quality unheard of at this, such as Rubycon and WIMA caps, Toshiba output transistors and dual voltage regulators, Alps motorized volume control, gold-plated input- and output posts and so on. The power supply section contains the signature Shengya beefy power transformer serving voltage to the preamplifier and amplifier sections that are separated by steel chassis gates. Over all, the Shengya A17 delivers a great, and rich warm sound, mellow, musical, with high density and great dynamics, and yet has the damping factor to drive even the most troubling of speaker loads. |
