Ultra High Performance Modifications & Optional Upgrades
Statement Level Modified HDP-3 w/optional ASi B-OTM (Bamboo, Off The Mains) custom battery supply!
DEQX HDP-3  6 output channel High Performance Modification/Rebuild- $1395

Introduction:
The focus of this High Performance modification/rebuild package is to extract high levels of additional performance from the HDP-3 unit. The modification
approach used will outperform the optional factory upgrades and minimalize the analog output stage parts drastically to ensure stunning performance.

Input Digital Connection upgrade
Replace stock input coaxial spdif connection with Vampire RCA coaxial connector, wired with silver wire into circuit.

Master DSP Clocking upgrade
Replace stock TCXO master DSP clock with NewClassD Dexa D-Clock clocking circuit to inject a low noise output signal frequency, allowing the DSP circuit to
provide better overall performance. This clock has a built-in isolation transformer to remove ground loops from the grounding of the power to the clock signal
output.

DC Voltage Regulation upgrade
Replace stock voltage regulation with the Dexa UWB Voltage Regulation (Ultra Wide Band, Ultra low noise performance) for cleaner voltage rails feeding critical
digital circuits.

Complete analog output stage rebuild
Completely bypass entire stock DEQX analog output circuit and rebuild from the ground up with the best sounding IC based opamps on the market from National
Semiconductor for current to voltage conversion from the Analog Devices DAC chips.  Dual differential output from the upgraded opamps feed into 6 high quality
audio signal coupling transformers which summize the signals, minimalize the output stage circuit, and provide signal isolation from external components
connecting afterwards. The output is 100% true balanced via added XLR connectors (RCA signal ended outputs can also be available on request). The new
optimal analog output stage parts are mounted carefully on a oak wood platform. Output Wiring is done with custom ASi speced silver wire coated in natural
unbleached cotton tubing for the most natural tonality.

additional proprietary circuit tweaks performed for enhanced performance.
DEQX HDP-3  6 output channel Statement Modification/Rebuild- $2495

Introduction:
The focus of this extreme modification/rebuild is to extract maximum performance from the HDP-3 using some of most advanced state of the art parts available
today. This specific rebuild package is similar to the High Performance version, with the main differences being the main core parts (clock, opamps, connections,
etc) are upgraded to the finest available for accelerated performance improvement.

Input Digital Connection upgrade
Replace stock input coaxial spdif connection with WBT Nextgen RCA connector, wired with silver wire into circuit.

Master DSP Clocking upgrade
Replace stock TCXO master DSP clock with NewClassD Neutron Star Flagship clocking circuit to inject a very low noise output signal frequency to allow DSP
circuit to work to its maximum potential for enhanced performance. This clock has a built-in isolation transformer to remove ground loops from the grounding of
the power to the clock signal output.

DC Voltage Regulation upgrade
Replace stock voltage regulation with the Dexa UWB Voltage Regulation (Ultra Wide Band, Ultra low noise performance) for cleaner voltage rails feeding critical
digital circuits.

Complete analog output stage rebuild
Completely bypass entire stock DEQX analog output stage circuit and rebuild from the ground up with 6 Burson Audio HD Opamps (discrete circuits, not IC
based, for best performance) for current to voltage conversion from the Analog devices DAC chips. Dual differential output from the burson audio HD Opamps
feed into
6 very high quality audio signal coupling transformers which summize the signals, minimalize the output stage circuit, and provide signal isolation
from external components connecting afterwards. The output is
100% true balanced via added XLR connectors (RCA signal ended outputs can also be
available on request). The new optimal analog output stage parts are carefully mounted on a oak wood platform. Output Wiring is done with custom ASi speced
silver wire coated in natural unbleached cotton tubing for the most natural tonality.

additional proprietary circuit tweaks performed for enhanced performance.
NewClassD Ultra Low Noise Power Supply Upgrade for NewclassD clock circuits (115v or 230v)- $295
This ultra high performance power supply will eliminate noise to any of the clocks we install. This removes shared power supply noises to the clocks power circuit
and offers much blacker backgrounds, extra dynamics and resolution. If you choose our B-OTM battery supply, you will not need this DC power supply option.
Bybee filter upgrade, $100 per application.
Applications include input spdif signal, analog input signals, clocking signals, analog output signals (recommended one per XLR phase, 2 total, or 1 per each
RCA output). Please inquire for more information on how many bybees would be right for your project.
ASi B-OTM dual voltage battery supply. $995
Do you require the best performance possible from your DEQX? Remove the AC mains distortions from all critical processing circuits for a major jump in overall
resolution, dynamics, transparency and natural tonality. This optimal battery power supply provides +12v/-12v to power all critical DEQX processing circuits,
clocks, analog input and output circuits, etc.  Enclosure made from beautiful bamboo and uses two special low impedance SLA AGM batteries and internal
battery charger.  The HDP-3 is prepped to allow the battery connection, on/off switch installed on the rear and circuit mods are needed to allow use.
Optional performance upgrades:
Here is a glimpse of the statement modification.
Many hours of tedious work goes into this great
rebuild using some of the most technological
advanced parts available today.
The ASi B-OTM Dual Voltage Battery Supply!
Made from beautiful bamboo, this supply
powers all the critical circuits within the
DEQX HDP-3 to ensure the maximum amount
of performance at any given time of the day!
Analog Input Modifications-
Analog input circuits can be modified on request $100 per set of stereo inputs. Such improvements are even better opamps in place than stock, signal
optimization and circuit parts improvement for enhanced performance.
