The Teac Reference 7 (or NR-7CD): based upon a monaural differential circuit design

22nd January 2017

The Teac Reference 7 (or NR-7CD) combines CD/network player, DAC and power amplifier in one box


Supporting DSD 5.6Mhz and PCM to 192kHz, the Reference 7 can convert/up-sample signal up to to the DSD 12.2 MHz format and up-sample PCM digital signal to 384 kHz via a proprietary FPGA design.


Wireless streaming, via Bluetooth supports the LDAC codec while the box also features a full-stage monaural differential circuit design, the chassis includes an ICEpower Class D amplifier.


The company has mounted the DAC and the preamplifier on one side of a 10mm thick high rigidity aluminium block and the power amplifier module on the other side to lower noise and the heat radiation effect of the power amplifier.


Teac also uses its own OVCS (Octa Volume Control System) to improve sound quality. It features a, “…ladder resistance switching-type volume including eight circuits. The positive and negative sides of the left and right channels are independent and further separated by two circuits in parallel, linked together.”


The Reference 7 supports both Tidal and Qobuz streaming audio plus Android and iOS control apps. Finally, and you can vary the brightness of the VU meters over three settings or, indeed, turn the lighting off. Price is TBA.
