Introduction
With its AES and XLR outputs and decoding capability of PCM 384K & DSD256, the NuPrime
DAC-9 is a reference-class DAC designed for studio professionals. With four digital and one
analog stereo inputs, the DAC-9 is a full-featured DAC and preamp ideally suited for high-end
systems. The DAC-9H differs from DAC-9 with additional balanced 4.4mm 'Pentaconn' socket
and 3.5mm standard stereo headphone outputs that support Single Ended Unbalanced, Fully
Balanced and Active Balanced Ground Driving headphone amplifier.
A Reference LE Class Preamp
To meet the requirement of customers who want to eliminate extra components in their system,
a high-end preamp capable of driving the power amplifier directly is an essential part of the design.
The DAC-9 includes features borrowed from traditional high-end preamps:
State Of The Art Balanced Headphone Amplifier
The DAC-9H headphone amplifier is capable of driving the most demanding headphones, be it
through the balanced 4.4mm 'Pentaconn' socket or the 3.5mm standard stereo socket. The
'Pentaconn' socket (manufactured by Nippon Dics Co.) is the new unified standard for balanced
headphone connection which headphone and cable manufacturers are using in their new and
future products. Audiophile quality components and a fully balanced layout ensures minimal
crosstalk and maximum channel separation. Supplying up to 1.2W of output power, the circuitry
supports Single Ended Unbalanced, Fully Balanced and Active Balanced Ground Driving. Besides
offering a high level of transparency through both types of connection, each offers a slightly
different flavor.
Through the 4.4mm 'Pentaconn' socket balanced output, listeners will appreciate the pristine
background with the absence of noise. The soundstage is wide and possess a strong presence
with a full and extended bass.
Through the 3.5mm socket low impedance output, the sound is clearly outlined and has a sense of
naturalness. The midrange performance is a prominent highlight and imaging is solidly focused.
