Stello Ai 500，这个螃蟹谁来吃？


2010 Stereo Sound Grand Prix

Preamplifier section

The Ai500's solid-state circuitry includes high-speed, low-noise transistors, and direct coupling throughout. Meticulous ground isolation techniques insure superb signal-to-noise ratio. Much care has been taken in the selection of components and the layout of circuitry for low noise, fast response time, and linear frequency response. We are confident that the Ai500 is among the very best preamplifiers on the market, at any price. Small-signal capacitors, where needed, are all 1% tolerance Wima brand resistors.

Power amplifier

Stello Ai500's output stage employs matched Hitachi MOSFET power transistors in Class AB push-pull configuration. Class AB offers the best trade-off between high performance and high efficiency. Input circuitry, gain stage, drive stage and bias net are April Music's unique proprietary circuitry, with optimum signal transfer and minimum phase shift.

D/A Converter

Digital signals received via COAX and OPTIC inputs are processed by the digital input receiving circuit. Likewise, the USB signal from a PC enters the USB DAC through the digital input receiving circuit.

Power supply

Separate power supplies deliver super-stable DC voltages to the preamplifier and DAC circuits. The power amp's supply has tremendous current reserves for lifelike dynamics. With an overlarge 800VA toroidal transformer, fast-recovery rectifiers, and an enormous capacitor bank (90,000uF), the Ai500 will never "run out of breath" even with the most demanding music and the most difficult loudspeaker loads.

Connectors

Ai500 features Neutrik balanced connectors, gold-plated RCA jacks, and gold-plated speaker terminal binding posts.

造型看似很防弹，我咋想起了小不点呢:Q

But at $3495, the Ai500 needed to do more than just look good.

竟然有个 ipod 的 usb 口，不走 lod 线的话，直接转 usb，应该是买水果的授权了，貌似有授权的厂越来越多了
