New full-size separated components in the Reference series, the AP-701 and UD-701N will be released


TEAC Corporation (TOKYO:6803) will release the first full-size separated components in the Reference series, a stereo power amplifier AP-701 and a USB DAC/Network player UD-701N.

The AP-701 is a new flagship stereo power amplifier that merges all the elements desired in a power amplifier at a high level, creating a new standard.
Accommodating independent left/right high-capacity toroidal core power transformers, discrete buffer amplifiers and two Ncore modules to provide a complete dual mono structure from input to output, while the input stage of each channel employs a fully-balanced design, so the dynamism of input signals is amplified as is, maximizing the innate performance of the speakers.

The cabinet is primarily comprised of 3mm-thick heavy metal platel but has a flexible structure to control vibration. By incorporating joints with suspension functions, the vibration frequency of the entire device is controlled to reproduce open and vibrant sound.

The UD-701N is a new flagship USB DAC/Network Player that combines a network player, an analog preamp, a headphone amplifier and various other functions on the advanced USB DAC function, accommodating a newly designed TEAC ΔΣ(Delta Sigma) discrete DACs.

As a USB DAC and network player, 22.5MHz DSD and 384kHz/32-bit PCM are supported. Employing the newly-developed TEAC ΔΣdiscrete DAC, all digital signals are converted to analog signals with high audio quality.

Not only can this be used for all kinds of digital playback, from systems centered on a PC or Mac to audio server systems using NAS and streaming playback, it can also fulfill a core role in systems as a preamp with analog and digital inputs. Along with allowing listening through speakers in combination with a power amplifier, it also supports balanced headphone output using a 4-pin XLR jack.

The UD-701N is an all-around unit that flexibly supports new listening styles in a new age.
