Commentary
CD player equipped with new generation unicorn system.
The D/A converter is equipped with a new-generation Unicorn system, which is called the Philips D/A conversion system and consists of TDA1315, TDA1307 and TDA1547.
It consists of the TDA1307 (DF7), which contains an 8 fs digital filter and noise shaper with excellent out-of-band attenuation and group delay characteristics in one chip, and the TDA1547 (DAC7), a proven switched capacitor. Combined with the non-feedback I/V circuit and balance amplifier in the latter stage, it realizes an excellent analog output.
The LHH Series design eliminates all NFB from the D/A converter to the amplifier and power supply, eliminating the influence of high-frequency noise caused by NFB circuits.
It is equipped with two optical and one coaxial digital inputs so that it can be used as a control center for digital sources.
The DAI receiver uses the latest device, TDA1315.
Equipped with a digital volume, it can be adjusted up to -60dB one step at a time.
Swing arm pickup mechanism CDM-9 is adopted for the mechanism part.
Equipped with fully symmetrical balanced output.
A double-sided copper foil board is used for the circuit board to minimize the ground impedance and obtain high shielding effect.
The internal layout adopts a center mechanical arrangement, and the digital circuit and analog circuit are separated into left and right to eliminate mutual interference.
In addition, by adopting a copper-plated mechanical cover, it demonstrates a high shielding effect and realizes excellent quietness.
The chassis is made of 2 mm thick steel plate shielded by all copper plating.
The legs are equipped with a 3-point grounding sintered alloy insulator that is highly earthquake-resistant.
The front panel uses a Eurogray design.
Wireless remote control is included.
