Esoteric G-25U, Specifications

Page: 2 / 4

The G25U also includes digital audio up conversion , allowing you to output a digital
audio signal path at selectable levels up to 192 kHz. Re-sampling the digital data stream
(up to 32 times), allows for red book CDs and DVDs to sound better. Ambience, depth of
field, imaging and clarity are all dramatically improved.
Note: This unit up-converts linear PCM signals only. Dolby Digital, DTS or other format
signals cannot be up-converted.
Up-conversion “upgrades,” the investment you have already made in DVDs and CDs.
Your collection may astonish you once you begin to hear what you have been missing!
In addition to user selectable up conversion, the G25U includes proprietary Esoteric
digital filtering . This effectively reduces noise artifacts and allows the digital signal to
actually sound more “analog.”
The G25U has a rigid body construction combined with elegant styling.
2mm thick steel chassis and 15mm aluminum faceplates are used. Three pinpoint
isolation feet support the chassis. These feet maximize the stability of the crystal clock
by allowing the unit to be mechanically isolated from internal and external vibrations that
can affect the accuracy of the clock. The front panel design is highly elegant with a
brushed aluminum finish. The front panel displays all the current settings at all times.
Conclusion:
The G-25U is a hybrid “PCM digital audio up converter” and a 'master clock generator'.
As a D/D converter, it can convert digital audio frequencies from red book CD standards
all the way
up to 192 kHz, improving sound quality by over sampling and re-timing a
PCM digital audio data stream. As a master clock generator, it can process word clock
signals by its internal, high precision crystal oscillator. This master clock is accurate to
+/- 1ppm. (Measured as 1 part per million. Most conventional CD/DVD devices are
accurate to +/- 10-50 ppm).
