The potential of your system starts with the source and clean stable electricity, free of radio frequency band and electromagnetic contamination.  Dedicated lines do nothing at all to eliminate radio frequency contamination entering your high-end gear.  Our listening rooms are all full of radio frequency contamination given off from cell phones, pagers, cordless home phones, digital alarm clocks, anything that is digital, wireless computers and their routers, radio and TV broadcasts.  The RFI contamination they silently give off contaminates your system and robs it of it's full potential.  A good line conditioner, isolation transformer and specially shielded cables are necessary to achieve State of the Art performance on top of our Signature Edition upgrade for each of the components comprising your system. 

  Be aware that expecting a new preamp or amplifier to dramatically improve upon sound quality they are not receiving from the source is simply not possible and highly illogical.  The signal to noise ratio and level of resolution are both dictated by the source component.  

  We highly recommend purchasing directly from Upgrade Company a brand new Factory Authorized Esoteric Digital source component that has been upgraded with the Signature Edition upgrade.  It's the first step toward achieving a State of the Art live sounding Hi-Fi system.  Worldwide sales inquiries are invited.

The Upgrade Company tests new top of the line models and performs double-blind multiple participant A-B test sessions to be sure that our claims of "State of the Art" are up to date.

  A FEW NOTES ABOUT "MODIFYING" YOUR CD PLAYER YOU SHOULD BE AWARE OF:

Several modification firms and manufacturers have been pushing consumers to add-on aftermarket "superclocks" and "masterclocks" to make money.  These "clocks" have been scientifically proven to be a total waste of money and a very bad idea.  The final jitter performance goes to hell in a hand basket.  Measurably.

Here's why:

 "SuperClocks" and "Master Clocks" HURT sonic performance due to Vibration and RFI/EMI induced distortions!

Some CD & DVD player modification companies have convinced their customers to install an aftermarket "clock" to enhance the sound of CD & DVD players. They claim the "jitter" will be lower, resulting in enhanced sonic performance.  That claim is false.  Sure the parts per million accuracy of the timing element deep inside the clock circuit is more accurate in terms of parts per million error.  That part is true. 

However, what these "clock" proponents fail to realize and fail to measure, is that the actual final parts per million error rate by the time the wiring reaches the circuits being "clocked", goes HIGHER.  Especially when the player is subject to vibration from the spinning CD/DVD disc and vibration from the speakers. The unsupported and unshielded wiring strung all over the place causes jitter to become measurably increased. 

Subject the player to everyday typical vibration and the sound quality goes to hell in a hand basket.

In addition to the detrimental affects of vibration induced distortions, there are serious sonic degradations caused by RFI and EMI contamination, again in the wiring of these "superclocks" and "master clocks".  

MEASURED jitter goes WAY UP with the cobbled on internal "clock".  Listening and measurement test confirm: these "superclocks" should be removed, and their practice stopped.   There are better solutions.

Internal "Superclocks" are typically installed by aftermarket "Mod" firms with hotglue. All of these clocks
require that new wires be strung around inside of the player to/from the circuit board and to/from a power supply somewhere in the player.  This is a big problem. In outboard "Master" clocks, interconnects must be strung to and from the existing player.  Big problem.

In either case, the wires or interconnects are always unsupported, loose, prone to vibration, and higher in resistance, inductance and capacitance, unlike a circuit trace that is extremely short, low on capacitance, resistance and inductance, typically shielded on at least 1 side, and not prone to vibration.  

The unshielded & unsupported wiring needed to install a "superclock" actually creates a TON of jitter once the speakers and CD vibrate the chassis of the player.  The jitter goes through the roof from vibration.  It's these vibrations that are transferred to the "clock" wires that set them in motion, actually generating a small electrical charge through the phenomenon of "microphonics".  These actions combined significantly degrade delicate timing and data-stream integrity.
The degradation is measurable. 

For many years The Upgrade Company has tried to get these add-on "clocks" to work as advertised, yet the measured jitter performance has always been worse over upgrading the stock clock which has literally no wiring or additional parts to collect EMI, RFI, nor vibration. 

The sound in the worst cases becomes very congested and harsh:  Turn up the speakers and the sound gets worse. This phenomenon of vibration-induced jitter degradation also applies to outboard "Master Clocks."  These expensive outboard "Master Clocks" often do more harm then good, MEASURABLY.

$13,000 Esoteric G-0S Master Clock customer comments:

"I owned an Esoteric UX-1 and later added their G-0S Master Clock, the first one in the US actually,
several years ago.  The G-Os was always a controversial addition for me.  At first I
thought it was a benefit, but over time I decided that it made the sound un-natural.
The benefit, if any, was subtle and many would argue that it was not really better
sounding.  So I agree with Dave, don't bother with it.

Thanks,

PLEASE NOTE: Due to heavy demand for The Upgrade Company's services, we must schedule upgrades in advance and now give RMA #'s. We are extremely busy because each upgrade takes days to complete and we do not have a full time Customer Service staff. Much of our workload is from repeat customers and referrals. Our advice is for those who have heard our work and are ready to have The Upgrade Company bring a component up to true "State of the Art," to indicate so in your telephone message or email, and we will return your call to schedule your upgrade. Our customers report to us based on their independent comparisons, that it is not possible to obtain the superior results we provide them, nor the full 7 day In-Home Money Back Guarantee we offer, anywhere else.

A NOTE ABOUT EMAILING: Many of our email responses over the past 24 months have been blocked as "SPAM". We definitely respond to each and every email at all times within 72 hours or less. We have had this policy in place for over 24 months. If you have not received an email response from us to any email, even 1, then by all means please telephone us directly at your earliest convenience. If we do not answer we are in the lab and in the workshop working hard for customers 24/7 full time even until late at night. We will call you back to keep your phone costs to a minimum.

Thank you for your continued support!
