Black Gate Standard
The Upgrade Company has plenty of Black Gate capacitors in stock, although they have been long discontinued.
They are still "State of the Art" & "The World's Best" electrolytic capacitors in many circuit applications.

"Own the very best!"

Stock high-end audio gear still leaves a lot to be desired.Even ultra high end models simply fail to come close sonically to the same model which has been upgraded.

Why should I "Upgrade"?

Aren't the latest magazine recommended models better?

Sorry, not even close. Manufacturers are out for profit. All stock audio and video components, even models listed in magazines this month, lack the best capacitors, resistors, diodes, wiring, voltage regulators and shielding, so in comparison to an upgraded version of the exact same model, they sound dull, flat, anemic, thin and boring. Manufacturers are driven by profit; it's simply not possible.

The Upgrade Company would not be in business full-time and growing otherwise.

Stock high-end audio lacks high-resolution and it sounds flat, thin and boring. Even the supposed "State of the Art" $10,000-$50,000 CD players we buy for our own in-house comparisons pale to far less expensive CD players which we have upgraded. Our customers agree.
There are no downsides to our work of replacing the standard variety "for profit" parts with the very best technology affords us. Unfortunately there is no manufacturer using top quality best-sounding parts. The only option is to upgrade, but even that is easier said then accomplished: you have to know exactly what parts work where and in which unit, how to solder properly, how to read schematics, how to repair, etc.

This is where our 28+ years of experience cashes in for you. We take your old CD player, preamp, power amplifier or receiver and make it outperform the latest makes and models, GAURANTEED.

Nearly any make or model is a good candidate for upgrading because it is far more cost effective then buying a brand new unit or even a more expensive used model. Buying and selling stock audio gear is akin to going sideways, trading one mediocre product for another. Once upgraded, most models outperform stock state of the art models as heard on the showroom floor.

Please take a few moments to read some of our real customer testimonials that can be trusted as accurate. Our customers have ranged from a Catholic Priest and practicing Reverends, to actual magazine reviewers to life-long high-end audio hobbyists, while others are relative newcomers to High-End Audio and Video. Each and every testimonial was given to us on the customers own merit after paying for the upgrade service.

We have never accepted a testimonial nor review in exchange for any work whatsoever at any time. Every testimonial and review is REAL.

The Upgrade Company has literally tens of thousands of cost-is-no-object parts in inventory, from no longer manufactured Rubycon "Black Gate" patented electrolytic capacitors recognized as the worlds finest in many applications (but not all) as well as many other brands of electrolytic capacitors and the latest high end film capacitors from V-Cap, SoniCap, and others. We have a wide variety of cost is no object resistors/voltage regulators/diodes wiring and connectors in stock at all times. We also carry and recommend Bybee Quantum Purifiers as an optional extra on some models that benefit from their use.

We know exactly which parts perform the very highest within each model, based on both measurements and listening comparisons. What we do and what we achieve are unique in this industry. Our 100% Satisfaction Guarantee speaks volumes about our effectiveness.

We know exactly how to "voice" every model down to a science. Our "Signature Edition" upgrade provides you with the music itself: totally clear, full-bodied, lush, liquid, 3 dimensional, lively, non-forward, highly musical dynamic & powerful presentation that leaves the latest Class A rated and "Editors Choice" units sounding unsatisfactory due to all the inferior "For Profit" electronic parts, often well over 100 "For Profit" electronic parts in the latest "Class A rated" "Editors Choice" models costing in the neighborhood of $25,000 to $80,000 US Dollars. Factory-built brands even at their sky-high prices sound thin, dull, and downright irritating in comparison to the same model which has been "Signature Edition" upgraded by The Upgrade Company, despite using cost-is-no-object cabling and cost-is-no-object speaker systems.

It's no wonder un-upgraded models sound dull and flat with 100-200 cheap parts sold in it. The most expensive highest performing parts, wiring and shielding work sonic wonders on any model, provided you really know what you are doing. All of our parts and labor are warranted.

The source component is the most important. You should upgrade your source first, with your preamp a close second. Upgrade Company digital far surpasses vinyl analog LP's .

It's no wonder stock OEM models sound dull and flat once you know they contain 100's of cheap parts and no shielding on any wiring. The most expensive highest performing parts, wiring and shielding work sonic wonders on any model, provided you really know what you are doing.

All of our parts and labor are warranted for at least 1 year. Extended warranties are available for new products we sell.

Regarding our posted samples of testimonials and reviews, we will provide the authors contact information upon request.
