€40,000 pr
The Vilobha monos are paralleled single-ended 20-watt amplifiers whose signal path consists of a C3m input pentode in triode connection which is direct-coupled to an EML 45 driver that's interstage-coupled to two paralleled 75TL. One EZ80 rectifier supplies the input tube, two 6D225 act a 15-second high voltage delays.
For onboard iron there's a grid choke to bias the C3m with an LED bypass; two 10H choke filters for the high-voltage supply; two 10H 100mA choke filters for the low-voltage supply; one double C-core transformer with separate windings for the high/low voltage supplies; one double C-core transformer with separate windings for all the tube heaters; and one double C-core output transformer that's claimed to be flat to 70kHz.

谢谢，刚好昨天在杂志上找到代理信息。
有谁用bella luna这对箱吗？搭配什么样的前端呢，效果如何？

我很好奇没人提起 何庆华 睿志音响 Audio-GD 的产品？
他们的产品在 http://www.head-fi.org/f/7/dedicated-source-components 已讨论好几年了。
在 Australia 好多人 fight to represent him.

Audrilabs Novachord is an integrated amplifier based on a hybrid preamp running in class A. This preamp drives an analog class D power stage. The classic 6H30Pi Russian twin triode is the tube of choice because it works with very low resistor values in the signal path.
This design is free of global negative feedback and there’s only very little local negative feedback. There are two mono preamplifiers and two power amplifiers into one chassis.
Inside the Novachord there are four toroidal transformers. The power stage is fed by a huge 1.4KVA power toroid with a 88.000µF capacitor bank to generate 500 watts into 4Ω. Each preamplifier channel with its multi-layer circuit board has its own toroidal power transformer and separate power supply. The fourth transformer feeds the LCD, touch-screen management micro controller and tube heater supplies.
Volume attenuation is via a DACT 24-position stepper attenuator.
With its orange/black touch screen for input/bypass/setup selection and that lone multi-function master control, the Novachord presents an exceptionally tidy and modern face to the world.
Novachord has 3+1 RCA+XLR inputs and one pair of top-quality Furutech speaker terminals.
Power specs are 220/500w into 8/4Ω. Peak output current is 46A. Frequency response is 4Hz to 60kHz ±3dB. Damping factor is 1.500 @ 1kHz. Dimensions are 480 x 474 x 154 DxWxH.
