Modification Package Descriptions

Ultra low impedance capacitor replacements-
We replace an abundance of the cheap SMD style board voltage rail decoupling capacitors in all critical areas inside of the 170i to
the ultra low impedance capacitors by Rubycon and Panasonic. Very Nice improvement! A HUGE change in total sonic tonality and
character. The stock capacitors are very poor in comparison of the factors of impedance and ripple current & will not let you realize
the full potential of this unit!

DEXA UWB (Ultra Wide Bandwidth) Ultra Low Noise Voltage Regulators-
The DEXA UWB Regulator is a high end ultra low noise replacement to the OEM SMD +5vdc & +3.3vdc voltage regulators used to
regulate DC voltage in the 170i transport. All critical IC chips and circuits run from these regulators. "Your performance is as only
as good as the power feeding the circuit..." Unfortunately the OEM SMD regulators have very poor noise performance. Especially
since there are noise sources around the OEM regulators, like ripple or load fluctuations.  In comparison to all the OEM regulators,
the UWB's have more than 100 times better ripple rejection, 10 times lower noise, and no line and load regulation error. The result
is a
drastic improvement across the entire spectrum and more dynamic range. A complete eye opening improvement!

EMI/RFI Shielding to ENTIRE unit chassis and some mod parts-
This is critical! Your other pieces of gear (cablebox, computer, router, etc) internal clock resonators that spurn off spurious
emissions and ruin your Wadias sonic performance by overloading the digital and clocking circuits. Local RF transmitting towers
(AM or FM) depending on where you live can also interfere as well as your smartphones transmitter. Careful shielding of the
chassis/lid, power supplies, clocks is a must for best performance. This creates a shielded cage and drastically tames down
ambient signals from penetrating the wadia chassis.

High Quality Vampire RCA Connectors for Digital output-
The complaint from our customers with the stock 170i  is the stock flimsy digital output coaxial connector. Connecting aftermarket
digital cables to this stock connector, especially with the Eichmann bullet plugs on them almost makes it feel like that connector is
going to break off!!  We replace this stock flimsy digital output RCA connector with a very high quality Vampire RCA jack mounted
onto the chassis of the rear of the 170i to vastly improve the signal integrity and rigidity over the stock jack!! This output is also
enhanced as its wired via cryoed Silver Wire from the digital output section. This is a must!!

We can also install a BNC connector instead of this RCA connector upgrade. (No Charge)
Due to popular request, we can install a WBT Nextgen RCA Connector for the digital output instead of the vampire connector. This
will add $50 to the costs. Please note that if your using eichmann bullet connectors that you must make sure that the ground pin is
connecting to the ground ring on the WBT nextgens.
Please email us after you have place your order to let us know and we will add this.
ASi "NO LIMITS" Ultra High Performance DAC Output Section-
The shortest signal path is the best path for the best sound! This is our theory and we make it a realization by adding a custom "state
of the art" digital to analog output stage board inside the Wadia 170iTransport.  This now allows the Wadia 170iTransport to be
directly connected into a preamplifier, integrated or receiver and the extra costs of additional cabling and outboard DAC are now not
needed.  Details of the DAC board upgrade include the finest sounding flagship 24/192khz  D-A converters, ASi custom Silver Wire
and cotton tubing for all wiring purposes and the
finest quality audio signal coupling transformers. There are no signal resistors, no
signal coupling capacitors or any other such part in the signal path for the purest sound possible!!!!!

Here are the functional changes of the unit with this drastic upgrade:

Upgraded Digital output RCA jack is now a Digital Input RCA jack (BNC option, no charge, WBT upgrade $30 or 60 xtra)
Connect any other digital device (ie: PC Audio, CD player, etc..) into the ASi Modified iTransport for unbelievable performance!

Switch installed to select between "Ipod digital audio" and External Digital Audio
Switch is installed on the rear, flip the switch up and you will enjoy the digital audio from your ipod unit, flip it down to use the "digital
input" connector from any spdif source.

Analog "pass through" outputs are now the ASi DAC stage outputs
The standard "pass through" circuits are removed completely and the isolated RCA jacks are the new audio output jacks.  These are
the only "audio out" jacks on the unit after this upgrade.

All video output jacks work the same as a stock unit.

There are no software changes or any compatibility issues with the ipod section.

ASi can turn your Wadia 170iTransport into a "State of the Art" Digital to Analog Converter!

This is the
only internal DAC solution on the market! This has been designed to outperform any
outboard DAC out there. We have tried many in a-b comparisons.....No compromises!

You can have a world class lossless audio playback media server via your Ipod and DAC system
built into one nice little box!
Save your money & time and enjoy the music with the ASi "NO LIMITS" version of the 170i.

Time to forget those expensive digital cables, power cables & stock outboard DAC's! We have a
MUCH better sounding solution, that fits right inside the Wadia 170i or 171i!!  
ASi OTM "Off the Mains" optimal battery power solution for Wadia 170i/171i Sale $650
Imagine your Wadia 170i or 171i Transport operating on a optimal low impedance battery power supply, complete AC mains free!
Complete "off the grid" optimal battery supply performance! Play your music through your iPod and/or the ASi "NO LIMITS" DAC
section completely off the grid using a "properly" designed low impedancebattery supply for breathtaking performance. The OTM has
built-in autocharging, included is a external digital timer and power cord. The digital timer is preset to recharge the supply every
night (or your time preference) so the supply is always topped off and will never run down or out.  
No maintenance! Set and forget!
The digital timer acts like a high voltage switch, so there is never any AC inside of the battery supply while you are listening for the
quietest and best audio performance. The OTM enclosure is made from
EMI/RFi reduction aluminum and lined inside with wood
to create a subchassis for resonance control
, the color choices are Black or Gold. The enclosure size is 12"W x 12"L x 5"H
so this supply can mount below in a rack shelf or side by side to the unit if on a table.  The supply if used correctly should last easily 8-
10+ years. We have built hundreds of custom OTM supplies starting since 2006. This is the largest sonic mod upgrade we offer and
will gamechange the sonics of the Wadia into World Reference levels.

Custom made per order placed  (add extra 1 week or so). This replaces the stock wadia switching power supply and we
use the special 3 pin cable from it and adapt it to this battery supply.

DEXA Neutrino 2 Clock upgrade- Was $325 Sale $250
Replace stock oscillator for critical USB/SPDIF chip with DEXA Neutrino Femtosecond clock for vast improvement in overall
performance. This mod is necessary to get the most out of your wadia 170i! Lowers jitter to the processing chip for seriously
increased performance, far less noise (ie: jitter) means substantial performance improvements!!   The stock wadia has over 2000ps of
jitter, after this clock is added the jitter is under 1ps!

DEXA Neutron Star 2 Flagship Clock Upgrade- Was $695 Sale $550
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. This is the best
performing clock on the market and makes the Wadia 170 or 171i come ALIVE! This clock is an absolute must if your looking for the
best performance. 40% better sounding than the Neutrino due to built in temperature compensation circuit (thermostat), additional low
noise voltage regulators and RFI reduction material located around the clock oscillator.

Bybee Music Rails DC Power Supply Noise Filter Modules    $200 for 1 (Main DSP), $350 for 2 (Main
DSP/Dexa Clocking upgrades),
$450 for 3 (DSP/Dexa Clocking/ASi No Limits DAC circuit board), $550 for 4 (2 for Main DSP, Dexa
Clocking upgrade/ASi No Limits DAC circuit board). Bybee Music Rails are
patented DC power conditioning noise filter circuits that
are installed at the tail end of the modified DC power supply to the load of the critical audio processing circuits inside the Wadia.

Highly Recommend Upgrade
, almost all orders get these because they make such a huge improvement by reducing noise up to
45db directly to voltage rails & circuit load! These are installed in-series at the end of the circuit load of the voltage rail feeding the
respective circuits and they move the noise on the power supply rails out of phase from the voltage  and drains it to ground, which
drastically drops the output noise, these music rails are a real
patented electronic noise filter circuit and are not a snake oil gimmick.
The sonic improvements are transient performance (speed and accuracy), detail/resolution increase (considerably less noise),
dynamics/bass response will be lower and tighter and stronger, and spatial resolution aspects dramatically improve as the sound
stage is now larger, clearly extending farther outside the speakers than before, and becoming deeper – and more precise individual
image locations within the stage.

Bybee Slipstream Filter Upgrade Sale $150
We add Bybee slipstream to purify quantum noises and seriously improve the sonics from top to the bottom of the spectrum. This is
used on the main power supply feeding into the upgraded voltage regulators.

"Elevating Lossless Digital Audio
Playback to the Highest Plateau!! "

The Wadia 170iTransport is another product that Wadia can put on their resume of "industry firsts". The first to extract bit perfect digital audio out of a
iPod/touch (or iphone) is surely an industry accomplishment.  ASi first got a look at the 170i at CES 2008 and we were eager to get one of these units to
implement into our new DS1 100% digital system that we were in the midst of designing at the time. When we first received our unit it did not take more than a
minute of listening to uncompressed WAV files to understand the potential of this innovative digital playback component.  Many hours of circuit studying,
listening tests and comparisons went into play to design the modifications that we feel will rocket the performance of your system to the highest level.  Hence
we came up with an affordable upgrade package that will satisfy any listener using the 170i in their system. We also developed some premium options for the
most demanding audiophile purists out there that will use this with their reference systems.

We had many customers ask us about this product and also outboard Digital to Analog recommendations. Our theory is "closest circuit path is always the best
for sound". So what does this mean?  KISS = Keep It Simple Stupid ! No expensive digital cables, no expensive power cables or extra power supply noise!
Even more importantly though, no extra connections, eddy currents, impedance, inductance, EMI/RFI, etc.... Basically, no extra added in "crap". So with this
theory in mind, we engineered (ok, hardwired...) our ultra high performance DAC board (an optional premium upgrade) into the 170i to accept digital signals
from either the iPod itself or from a newly added digital input connection (hook up your CD player or PC audio or whatever!) and transformer coupled the
output stage right to the RCA analog outputs (now isolated from the iPod pass through section).  Performance is now absolutely stunning to say the least. The
sound stage that this 170i threw out was so huge and deep. I knew I had something extremely special happening. This topology was completely optimal over
using any external DAC we have ever tried. Also any stock megabuck CD player that we have heard wouldn't be close to this level of sound either!
If your are looking for State of the Art performance using not only your lossless audio files on your iPod or any reference digital source you might have, you
owe it to yourself to save many thousands of dollars on unnecessary gear and get your Wadia 170i/171i modified to the ASi "NO LIMITS" Level today!!!

setup is great!  
What to expect after the ASi Mod to the 170i?
The overall sonic quality is taken to another level, pushing it several steps ahead and revealing shortcomings in the sound of
the stock unit. The sound stage opens up tremendously giving it more "freedom". There is much more realism and serious
reduction in any digital harshness that was present in the stock unit. More tonal texture with more weight and speed in
dynamics. High frequencies sound more relaxed and smooth, no more fatigue with extending listening sessions here. The
stock 170i unit with iPod playing lossless sounds compressed (or pinched) in comparison, a quick side by side comparison
easily reveals this. The ASi modification really makes the 170i sound like (or better than) a very expensive modified CD
player when coupled with a iPod playing lossless files!

thank you for convincing me to send in my Wadia unit... I had some hesitation in the beginning but upon return I was
graced with music that now flows out from the speakers in a very musical way. The bass quality has really improved,
alas the soundstage width-depth and overall definition is much more textured and resolute. I will send the unit back
without hesitation for the neutron star and possibly the dac output. I have great expectations.

Asi tek modified my wadia 170 with the modifications and the neutron star clock.
I am thrilled how my Apple lossless files sound now with my benchmark DAC 1. I tested various CDP's and CDT's to
the mod wadia/ipod classic combo and it has them all easily beat. I am one extremely satisfied customer.

First off my hat's off to ASi and what they done to my Wadia 170i transport...  I always wondered why no-one has built a
GOOD iPod type  HT type player yet? so I started looking into them all and ran across this Wadia 170i in the magazine Sound
and Vision and thought this is it!!. so I checked out what they was doing and said to myself he's got it!! what a idea a BUILT IN
DAC on this unit..so I ordered one with the neutron star mod & digital out mod  and I can't believe what I'm hearing thought
what sounds like a whole new HT set-up that I've had for a few years now!! yes this is very IMPRESSIVE and
UNBELIEVABLE,so I'll stop  there for now and tell you what I heard now,  the whole sound stage has woken up from the top to
the bottom and I mean woke-up!! I have about 100 plus hours break-in right now and the sound will get even better , first off
rich full vocals and bass that you just think of with a iPod/iTouch player, the whole dynamics of the music has been pumped
-up with that old school rich sound and depth in the music that you just can't get plus it's all in ONE UNIT!   so really just order
one you'll see..lol...  thanks

my HT system is the following  Outlaw 990 pre/pro, Outlaw 7125 amp 125wpc@ 7ways, 4 Outlaw 200wpc mono-blocks,Wadia
170i & Wadia connectors on the unit, CAL CL10 cd player, Rane THX44 HT equalizer , DBX 4BX expander, also not pictured
is a Denon DP-47F turntable with Monster cable connectors on it, all the power comes in through Monster Power Pro 2500
and a HTS 3500 power conditioners, all connectors are Outlaw and MIT Z-cords II on the Wadia & CAL, 4 Infinity Alpha 50's /
center is Alpha 37c, 3 500w Alpha 1200s subs / 2 alpha 20's for backs, all hooked up with M-series speaker cables and all 4
towers bi-amped with the mono-blocks running the low end.. these Infinity will sound MUCH better if you Bi-Amp them,     I'll
check back after break-in and finish this feedback so call this part one...lol.
