Please thank you.
AU-D707X attempted to improve the ability to reproduce bass enhancements, such as the power-based integrated amp.
Basic configuration of amplifier employs twin diamond X-amp.
Legacy amp sends current to the speakers from the + side, − side had become single-drive simply tied to the Earth.
Powered by pure focus and HS ones for speaker drive power supply stable even during peak charge-discharge characteristics of transient superior total 40,000 Μf capacitors and super heavy weight class power transformers.
Powered by MC transformer using to maximize the performance of MC cartridge, high purity, low magnetic distortion of manufacturerd.
Equipped with wood, with out of band resonant mode by the combination of metal and wood.
2 stages with a tone from tone selector switch type.
Equipped with the subsonic filter.
Phono input and CD input employs gold plated terminals.
Phono input with 4 positions for MM, High MC, MC transformer (High, Low).
Equalizer section employs discrete DC amplifier configuration Hi-Precision equalizer.
With the REC selector.
Type: integrated DC amplifier
