About ASi Teknologies
What does "ASi" stand for??

ASi stands for (Audiophile Sound innovations). The theory of radically
improving audio systems with the highest quality parts, innovative
concepts and complete circuit redesigns. This concept has been evolving
now since 1995, over 20 years!

We were internationally known for our Philips DVD-963SA and PS Audio
HCA-2 Mods and was part of the movement in 2003 which pioneered
modifications into the Toshiba SD-3950 slim line CD/DVD player that
gained massive popularity at the time.  We continue those style of mods
and even more innovative approaches into the Oppo Digital players
todayfor the best bang for the buck performance.  We are pushing
forwardmore than ever here in 2016, we have the extended experience
and knowledge over all other competitors.

Our room at AKFEST 2008, World premier of the ASi Digital
System 1 (100% digital system). Fully modified Oppo DV-980H
feeding DSD via DH Labs Silver HDMI into Panasonic SA-XR57
100% digital AV receiver fully modified, including modified
Silverline Audio Prelude speakers and ASi Silver speaker
wiring. ASi DPS (Digital Power Station) prototype in the
background was powering the whole system, No AC MAINS!

NOTE: This was the first time HDMI cable was ever used at a
Hi-Fi audio show to trasmit audio, the next people who did it
was PS Audio with their perfectwave transport/dac system.
Our room at AKFEST 2009, (Lots of different speakers to use).We were
showing fully modified Wadia 170i with ASi OTM battery supply (100%
battery powered) and a partially battery powered Panasonic XR-55 AV
Our room at AKFEST 2010, showing fully modified Oppo
BDP-83SE with ASi OTM Low Impedance battery supply running
majority of the Oppo BDP-83SE on tuned low impedance
batteries instead of the dirty AC mains for best sound.

"Since 1995"
Various pictures of our modifications, crossover
mods, and custom services found no where else
This is our fully modified Oppo BDP-105D with all mod options.
NoticeEMI/RFI shielding on the power transformer,power
supplycover,transport lid, etc. Notice all the other mods and
wiring done as well throughout the whole unit.
We can make you a custom fully modified, battery powered No Limits Behringer made in a
custom shielded enclosure. The ASi OTM battery supply also lives inside along with the
charging networks.
ASi is the only company to take the Behringer DCX2496 to these extreme limits of audio
reproduction. This custom battery powered processor outperforms ANYTHING else out there!
Wadia 170i custom modified along with ASi OTM
battery supply. This wadia is 100% battery
powered! Best sound possible!
100% battery powered fully modified Marantz SA-11S1
This is a full monty mod design using (2) ASi OTM's to
properly battery power the ENTIRE modified marantz
unit! This is an example of one of the best sounding
SACD/CD players in the world! This player need no AC
and sounds out of this world!
ASi OTM (Off The Mains) Low Impedance Battery supply,
can be retrofitted into most digital front end gear to
remove the AC mains, this is better than any switching/
linear power supply upgrades.

~Power cord for internal charging
~Digital timer
~30"  DC Umbilical Power cable w/Neutrik connectors
~Optional 220v to 115v converter for world wide usage

Battery connector, Heavy Duty ON/OFF
switch and IEC for internal AC battery
The ASi OTM low impedance battery supply is
available in Black or Gold EMI/RFI reduction
aluminum chassis.
This is our Statement rebuild to the Cary SLP-05 Preamp. DRASTIC
transformation over the stock SLP-05!  Check out the thick power
wiring, the point to point hard soldered silver wiring/cotton
tubing,V-Cap CuTF capacitors (tweaked with C37 GS lacquer and
RFIshielding), Bybee Music Rails, Front volume control bypass.
Cleanest/clearest preamp we have ever heard.
Dexa Neutron Star Flagship clock used in the Statement
Modification Rebuild for Oppo BDP-103/D and 105/D
Custom made high end crossover upgrades for the Emerald
Physics CS-3 open baffle speaker system. These were made
using Mundorf Mcoil flat inductors, V-CAP capacitors,
DuelandCAST resistors Eichmann cablepods, and hardwired
99.999% silver wiring (cryo treated) w/natural unbleached
cottontubing for the customer to solder at the speaker drivers.
Custom made high end crossovers with black wooden boxes
for another set of Emerald Physics CS-3 speaker system.
Munforf Mcoils, Vcaps, Dueland CAST resistors and captive
cryo treated silver speaker wiring coming in and out of
crossover boxes
Magnepan 1.7R crossover upgrade using VCAP
OIMP and CuTF capacitors. The inductors are
Mundorf Mcoils and cryo treated silver wiring
going back to through the panel to the
terminals. There was also Hi-Fi tuning
Supremefuses used on the tweeter section.
This all made one hell of an improvement!!!!!
This is a picture of our fully modified Wadia 170i w/ASi
NoLimits DAC stage and high end audio signal coupling
transformers. You can also see the Dexa Neutron Star
flagship clock, Dexa UWB low noise voltage regulators
and multiple Bybee Music rails and quantum filters used.
This custom modified fully modified Marantz SA-11S1 that is
100% battery powered! It uses two separate external low
impedance ASi OTM battery supplies, here you can see the
battery input voltages spreading out throughout the player
going into the Bybee Music Rails. Notice all  power wiring in
this mod is completely shielded.
Here is our Statement Modification done to the flagship
Wadia S7i CD player.  Please see the EMI/RFI shielding tape
on the power wiring, top of CD transport, side walls of
chassis and various other places. There is various Bybee
Music Rails installed, analog output rebuild w/high end
audiosignal coupling transformers. Dexa Neutrino clock
installed. Many capacitors were upgraded with Rubycon ZL
ultra low impedance capacitors.
This is our Statement Modification done to the Esoteric UX-1
Limited. The whole power supply was modified, ASi OTM low
impedance battery supply, 4 Bybee Music Rails added, Dexa
Neutron Star clock, Dexa UWB low noise regulators, analog
output stage rebuild with Dexa Discrete opamps and high end
audio signal coupling transformers sending the signals 100%
true dual differential balanced XLR! Incredible sounding player.
We do on-site upgrades and modifications. Here is a
fully rebuilt
Emerald Physics CS3 system. Upgraded
Beyma replacement speaker drivers, handmade high
end external CS3 crossover (in custom EMI/RFI
reduction chassis), Statement modified Behringer
DCX2496 , custom silver wiring.   These speakers
sound better than $100K speakers we have heard,
this system sounds truly World Class Reference!
Here is a huge crossover rebuild for a set
of Snell Tower speakers. There were
Clarity Caps, Mundorf M-Resist resistors
and a HUGE Munford M-coil inductor
upgrade for the bass drivers.
