Built-in channel, separate DA-Converter (Philips TDA 1541A), discrete output stage circuitry, fully enclosed Alps 4-Potentiometer, high quality MM/MC Phono preamplifier

In contrast to his circuitry very similar to that developed and produced in Japan predecessor, the Fine Arts A-9000, the A-9009, in addition, 3 digital inputs (each with 3x optical and 3x digital, switchable on the front panel). Each digital connection can process signals with 32, 44 or 48kHz sampling frequency, detection is automatic (via Yamaha IC YM3623B). The D/A conversion takes place channel-separated via a Philips TDA 1541A converter. However, there were no Silver-Crown (S1) D / A-Wanders installed on two amplifiers I repaired (I only found these in the CD-9009).

Volume control is done via 4-way potentiometer (the "blue" ALPS) as with the A-9000. Discrete power amplifier, driver stage again with hybrid module (STK3152), performance increase due to higher operating voltage.

Special feature: Phono MM and additionally Phono MC connection sockets, switchable on the front panel so that you can operate two turntables. Only the volume and audio muting can be operated on the A-9009 by remote control. On the back of the device there are 2 RCA sockets available with the RC5 bus, where, for example, a CT-905, which does not have an infrared eye, can be operated remotely.

The A-9009 was manufactured in Portugal and can also be recognized as "basic" when removing the housing cover on the boards and connectors (in contrast to the A-9000). The speaker connection screws are made of metal turned and gold-plated. They have a 4mm hole where bananas can be plugged in directly which can be very convenient.
