Statement Modification Rebuild Package Descriptions
~Bypass front panel left & right channel balance controls
These input balance controls are redundant and bottleneck the sound through the preamp as the signal travels through
more connections and then goes through a cheap potentiometers, and then through more of the terrible sounding stock
internal wiring (with connections at certain points, not good for sound..) all of this is bypassed with cryo treated 99.999%
silver wire in natural unbleached cotton tubing further wrapped in shielding and soldered directly to the main volume control.
This makes a good 25% improvement in overall sound.
~Main Power Supply upgrades & complete rewiring!
Replace and rewire the main fusing with Audio Magic Ultimate Beeswax Super Fuse (best available fuse on the
market! These cost $225 each!) for increased contact/surface area for better voltage throughput integrity. This statement
mod bypasses the fuse holders completely as the fuses are hard soldered inside the preamp (for the best sound
and performance) as we do not want to listen with our main power going through connections, as this creates additional
impedance's and noise and it throws grain/grit into sound with reduced bass/treble qualities. The fusing is C37 Gold
Standard lacquer treated to tone down 50/60hz resonance vibrations on the internal fuse network even further. Replace
all key capacitors in circuit with Rubycon Ultra Low Impedance capacitors for substantial improvement in power supply
filtering forboth power supply and signal circuit decoupling improvements! The power wiring that Cary used is too thin in
both of thepower supply section and preamp section so this is replaced with cryo treated 12awg Audio Magic Silver
wire which is about 2 timeslarger than the OEM wiring and we noticed considerably better bass and dynamics, better
control and larger soundstage and greater resolution and crisper highs.
~V-CAP CuTF Signal Coupling Capacitors upgrade (Amazing Improvement!)
Replace ALL of the inexpensive stock OEM Cary SLP-05 signal coupling capacitors (which are the Multicap PPMFX,
multicaps bottom of the line cap, and they use Cary branded Clarity bypass caps that are again inexpensive) in the tube
circuits with the incredible top of the line V-CAP CuTF capacitors for both the main signal capacitors and bypass capacitors.
These are V-Caps best sounding capacitors, having glowing reviews but are not cheap! The main signal V-CAP
CuTF signal capacitors used in this mod retails for over $450 EACH! The bulk of the cost for this mod comes
from the price of these capacitors so please understand that when you see the pricing further down the web
page! However you get what you pay for, and these are the best possible sounding replacement capacitors that can
physically fit inside the chassis! We have tried 7 different high end capacitors in this preamp and the V-caps have the best
sound. We found the best sounding signal coupling capacitor arrangement was using the V-CAP CuTF capacitors with
C37 "Gold Standard" flagship vibration resonance lacquer coating done to each capacitor, and then the capacitors
wrapped in RFI shielding tape and installed into the audio circuits. The results are staggering. The difference between the
stock inexpensive Multi-cap/Kimbercap (or Cary branded clarity cap as in newer stock SLP-05's) combos changed out to the
V-Caps is completely "Night and Day, No Comparisons!" Now the sound has no boundaries, and it has such a
transparent world reference sound quality to it you can't get in anything else out there! We have demoed many $20,000
+ stock higher end preamps and they sound closed down in comparison to our statement SLP-05.
~Signal wiring replaced with Cryo 99.999% 24awg silver wiring & cotton tubing
Changing out the stock stranded internal wiring (with it oxidized connections) (which has no place to be used in a $8,995
preamp) to our custom made cryo treated 99.999% Silver 24awg wire dressed with natural unbleached cotton tubing
bringsmuch more resolution, realism, (considerably better highs and bass response) and overall musicality within adding
inany brightness because we use natural unbleached cotton tubing for dielectric instead of synthetic Teflon, PVC or plastics
as this gives us the best overall balance. There is no silver brightness as that is caused by the man-made synthetic
dielectrics such as teflon or plastics as the signal travels on the surface (skin) of the wire, thus any thing directly touching
this wiring will be directly influenced into the music/sound. The natural unbleached has the more organic and natural
soundto it over everything else we have tried. All silver wiring is HARD SOLDERED into the circuits.
~EMI/RFI Shielding to SLP-05 chassis and internal wiring/parts
In its stock form, the Cary SLP-05 has really no shielding whatsoever throughout the entire preamp design. This allows all
ambient HF/VHF/UHF+ signals such as wi-fi routers, cell phones, radio station transmitters as well as other noises that are
thrown off into the air from your other components as they have clocks/oscillators inside them. These noises degrade your
sonics in a whole. The solution to this is to apply RFI shield tape along the ENTIRE SLP-05 chassis, the bottom cover, the
side walls, the power supply transformer and associated wiring, silver wiring, v-cap capacitor upgrades, volume control
motor, umbilical connection cable, etc. This adds a great shielding effect from stray noises and improves the overall signal
to noise which improves audio.
~C37 "Gold Standard" Vibration Resonance Lacquer application
Exclusively available only from ASi, the C37 Gold Standard flagship vibration resonance lacquer is applied in multiple
coatings to all modification parts (capacitors, bybee music rails, etc), power supply parts, and transformers to reduce
internal resonances on these parts for very hearable sonic improvements. There is considerably more subliminal
information and atmosphere around voices and underlying tones (many new natural organic tones heard across the
frequency spectrum) that were not present before the lacquer application and it only keeps getting better week after week
as the lacquer hardens and cures. The curing and break-in is about 10 weeks for this incredible resonance lacquer.
~Bybee Music Rails DC power conditioning modules upgrade
Bybee Music Rails are patented DC power conditioning circuits that are installed at the tail end of the modified DC power
supply to the load of a circuit. These are designed to reduce noise on these voltage rails up to 45db. This is about a 4x
noise drop! 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 with more precise individual image locations within the stage.
~Tube Socket Cleaning & Silver Contact Enhancement
The tube socket pins and power supply umbilical cord pins are cleaned first and treated with silver contact enhancer to
improve signal/voltage transfer qualities onto the necessary mating connections.
CARY AUDIO SLP-05 Preamp
"Statement" Audio Modification Rebuild
Any work or modifications to Cary Audio Design products voids the manufacturers warranty,
however we are now your service center and can perform any repair or service work to the
stock and modified circuits.
The Cary SLP-05 is a MSRP $8,995 flagship tube preamplifier that uses 6SN7/5AR4 tube compliment, has been well reviewed and won a
number of audio awards in the industry. We wonder what those reviewers were listening too as we do not find this preamp to sound too
good in its stock form, especially using stock tubes. We often receive emails from customers who own the stock SLP-05 preamp and
complain that "6SN7/5AR4 tube rolling to expensive NOS types" just doesn't do enough for sound improvement and it does not fix
underlying problems and issues with the overall sound and they feel their SLP-05 is the bottleneck of their system. The reason for this the
other surrounding signal parts in the tube circuits, such as the circuit signal coupling capacitors (which are inexpensive Multicap PPMFX
(multicaps bottom-of-the-line capacitor!) and Kimbercap bypass capacitors (or recently, Cary branded Clarity bypass capacitors) (these
have no place to belong in a MSRP $8995 preamp!), signal wiring (they are using multi-stranded wiring with plastic casing, multi-stranded
line level signal wiring is a big sonic no-no! Also a big sonic issue is the oem signal wiring is using a synthetic dielectric, (ie:such as
pvc,teflon or plastics), the sound of the dielectric will be immediately influenced into the music because the signal rides on the surface or
"skin" of the wiring, thus anything directly touching will have a influence on the sound (this is why we use natural unbleached cotton tubing
for most natural, pure and organic sounds, and most of all, proper tonal balance!). The power supply section uses THIN power wiring all
around and lack of RFI shielding. We found that replacing ALL of the power wiring to cryo treated 14awg (which is doublethe size of the
oem wiring), led to greater bass, dynamics, transients and overall spatial resolution improvement qualities. We have modified over 40 of
these preamps since 2007 and have tried many different signal coupling capacitors replacements. We found the best sounding signal
coupling capacitor arrangement was using the V-CAP CuTF capacitors with C37 Gold Standard resonance lacquer coating done to
each capacitor (the capacitors are further "tweaked", the plastic coatings are peeled,removing about 6-7 inches of plastic, this opens up
the sound more as all that plastic (synthetic material) is no longer heavily wrapped around the capacitors), and then after theC37 coatings
harden up (4-5 days after application), the capacitors are wrapped in RFI shielding tape (treated with C37 Gold Standard) and then
installed into the audio signal coupling circuits (adhesived so they will not break loose in shipping!). This gave us the cleanest, most
transparent sound with the largest soundscape and visceral definition and impact.
If you are reading this and own a Cary SLP-05, you own a great preamp, and its a perfect base to use for a world reference modification
rebuild to take it above any potential (much more expensive) replacement preamp you might have been considering. If you are not using
your headphone section and the tubes are still there, please take them out as there is no need to use them and they add more noise/heat
to the whole preamp. This is your chance to get your preamp done and out of the way for life, knowing there is nothing else out there off
the shelf that will perform like it because no one makes anything exactly like this using these high end world reference style of parts
(remember manufacturers have to build to a price point, they cannot build products from the ground up using costly high end parts).
Bottomline, there is no real sound in the stock SLP-05 (NOS tubes help, but only so much), please look down below at all of the
comparative pictures and the pictures of the stock signal capacitors and wiring used and you will see the reasons why.... We look forward
totaking your SLP-05 to its highest sonic level! You will be telling your friends and family about how incredible your preamp and system

If you do not have the budget for our Statement Modification, we can do a lesser costing
statement modification that uses V-CAP OIMP oil capacitors for the main signal capacitors
instead of the CuTF. Huge price differential. However we are still using the CuTF for bypass
caps so it would be V-CAP OIMP for main capacitors and CuTF for bypassing capacitors. This will
still sound incredible but it will not have the overall speed, clarity, resolution, and sound stage
that you receive with the V-Cap CuTF capacitors being used throughout.
