Ultra High Performance Modifications!

World Wide!
Introduction:

Bel Canto has done it again!  The New DAC 3 is a very decent performing DAC and
Preamplifier right out of the box. We dissected the DAC 3 unit to find a slew of parts
we needed to replace and rebuild around and wow what an improvement! Please
consider our price conscience mod package and much needed options to raise up
the bar of performance out of your DAC 3 to much higher SOTA levels!!
Basic Modification Descriptions-

~Power Supply Mods
Replace diode bridges with ASi custom hand selected ultra fast diode bridges to
remove grain/glare and increase resolution and bass. Replace all capacitors in circuit
with the Rubycon/Panasonic Ultra Low impedance capacitors for far less noise, faster
reacting circuits giving way with much more headroom.

~DAC Board Upgrades
We replace about a good number of capacitors across the board with the incredible
Rubycon & Panasonic Ultra Low impedance series caps. In addition, we replace the
stock opamps with the best sounding versions on the market from national
semiconductor. This really brings more life/speed/emotion into the music!

DEXA D-Clock upgrade $325-
Replace stock ultraclock oscillator with the D-clock to significantly improve performance
Drastically lowers jitter and power supply related noise to the DSP circuit for seriously
increased performance, far less noise (ie: jitter) means substantial performance
improvements!!  No grounds loops, complete isolation!

DEXA Neutron Star Flagship Clock Upgrade $695-
This flagship clock upgrade will replace the stock ultraclock oscillator that feeds the
internal DSP circuit for the very least amount of noise and jitter possible and the
highest potential of performance that is possible within todays technological limits.
No ground loops, complete isolation! A must if you require the best!
Highly Recommended Upgrade Options-
Clocking upgrades for SPDIF coaxial, bnc or XLR input use-
DEXA D-Clock upgrade $325-
Replace stock oscillator for critical USB/SPDIF chip with DEXA D-Clock for vast
improvement in overall performance. This mod is necessary to get the most out of your
Bel Canto DAC 3 for USB input! Drastically lowers jitter and power supply related noise
to the USB/SPDIF chip for seriously increased performance, far less noise (ie: jitter)
means substantial performance improvements!!  No grounds loops, complete isolation!

DEXA Neutron Star Flagship Clock Upgrade $695-
This flagship clock upgrade will replace the stock oscillator that feeds the internal
USB/SPDIF chip for the very least amount of noise and jitter possible and the highest
potential of performance that is possible within todays technological limits.
No ground loops, complete isolation! A must if you require the best!
Clocking upgrades for USB input (from computer source)-
NOTE:
Both clocking upgrades for SPDIF & USB can
be done at the same time if you use your DAC
3 with your computer and other digital inputs
for complete optimization! Awesome!
Complete Analog Output stage Rebuild-  $650 installed

Completely disconnect the stock Bel Canto discrete analog output stage (many
active parts) and replace entirely with passive very high quality Audio Signal
Coupling Transformers (also other parts upgrades included).

The stock Bel Canto DAC3 output stage is mediocre in build and rather decent in sound
quality. However, there are MANY ACTIVE parts in the signal path, such as op-amps and
transistors. There are also many resistors in the signal path as well. This is not the most
optimal topology for signal coupling and HF filtering.

Our approach is simple:
Completely disconnect the entire active analog output stage, and replace it with a set of
very high quality Audio Signal Coupling transformers!  Now with the transformers we can
now effectively and inherently provide galvanic isolation from other components in your
system. The transformer stops High Frequency noises that occur from other
components in your system. The also provide a means of connect the Balanced outputs
and RCA single ended outputs at the same time, with both having similar sonic
attributes. The noise floor in your music drops to a complete dark and black level. More
detail comes out of the music. The soundstage appears much larger, wider deeper with
a bold lifelike stance. Our approach is considered "state of the art" and this mod will
easily alone take the performance of this DAC alone to a level that is unattainable by
most out there if any.  

If your looking for the best sonic performance from your DAC3, this modification is a
must for a complete transformation of your sound.  Only available here at ASi!

Bybee Slipstream Upgrade $300-
We add bybee slipstream technology to purify quantum noises in the power supply
and seriously improve the sonics from top to the bottom of the spectrum. We have
been using the Bybee products since 2002 with great success each installation.
We get asked time and time over again to offer this great improvment as a
upgrade option on our modifications.
