High Performance

Need the ultimate in High Performance? Discover for yourself how much untapped performance High End audio really has!

Our SE upgraded versions of the latest models are State of the Art

Our unique RFI EMI RIDDANCE TECHNOLOGY strips millions of unwanted pulses from the signal paths power supplies all of which otherwise get reproduced right along with the music & video signals. This frees up 10-100 times the available power supply energy in any given millisecond to more faithfully reproduce the intended music & video signals to STATE OF THE ART Bass response becomes THE BEST as a result, so does liquidity, musicality, ease, palpability, slam, dynamics, sparkle, depth, articulation, clarity, extremely 3D live right before you feeling on music & film is just tremendous when the rest of your system has also been SE upgraded with the same unique RFI EMI RIDDANCE TECHNOLOGY. All brands of non-Upgrade Company upgraded high-end audio (and video) are highly compromised.  The latest magazine reviewed models fail to come close sonically to the same model which has been upgraded by The Upgrade Company.

Ultimate Level of Music

I am extending my sincerest thank you today to everyone at The Upgrade Company for helping me to achieve the high level of music & video performance I've longed to achieve for well over two decades.  I could never have achieved this ultimate high level of music as well as video reproduction without The Upgrade Company's help and unique knowledge.  This afternoon, I've been listening to my music collection and I cannot believe the incredible inner detail and sheer holographic realism present in recordings, even older standard 16bit/44khz CD's, all thanks to you.  Concert videos & movies look fabulous, nothing like they do in even in the best showrooms.  

Your Audio Research, EAR, Bel Canto, Oppo, McIntosh hardware upgrades have brought out the best in music and video reproduction I've experienced.  The TimePortal "RFI EMI Ridded" power cords, XLR interconnects& speaker cables are sonic stunners and really completed each system.  

I cannot thank you enough!  Thank you, thank you, thank you...

Extremely Satisfied Customer,

David,  Received the ARC REF 3 SE yesterday afternoon, and after several hours of use all I can say is... WOW!  YOU'RE THE MAN!  The resolution level of detail and audio performance is more like it!  Thank you, thank you, thank you, and THANK YOU!  It sounds GREAT!

I should really cool it financially, but what are your estimated upgrade pricing for my Audio Research PH5 phono preamp?

Thanks again,

Paul Elliott

I love you MAN!  (From an old commercial on TV)


October 2007

You'd be a little nuts to expect two "top-of-the-line" components like the ARC Ref 2 Mk 2 pre amp and the Reimyo CDP-777 could be improved. But that's exactly what The Upgrade Company achieved with a little bit of technical magic.   Upgrade Co. truly "upgraded" almost $24,000 (when new) units.  The enhancements include expansion of the musical space, dead-quiet, far more detail in the most complex musical passages and, that foolproof marker something's a lot better: "old" CD's suddenly seem new and exciting. I'd recommend The Upgrade Company without hesitation!

June, 2009

I have been an audiophile for well over forty years. I've collected more than 4000 LP’s over the years.  I'm nearing retirement,  so I decided to make my last system as musically satisfying as possible. With that in mind I bought new speakers and  amplifiers,  but I was not satisfied with the preamps I bought and nor those I had demo'd  so I looked forward to finding one that would finally fit my system's requirements.

I had planned to buy an AYRE Kx-r  and was perusing along AUDIOGON’s pages when I read that there was an ARC LS-10 for sale.  I e-mailed to inquire about an Upgrade Co. upgraded LS-10 advertised on Audiogon by a private individual but it was sold already. I called Upgrade Co. and they happened to have a later production LS-10 for sale that was more recently upgraded by 2 years with an IEC inlet installed and newer capacitor selections.  I needed 240v conversion to operate here in the French West Indies, so I agreed to purchase the newer upgraded LS-10 provided it was 240v converted.   I received the LS-10 two weeks ago  but I refrained from listening to it immediately.  David told me that the 240v conversion required 2 new transformers and would take aa bit of use to reach full potential.  He also said that if I didn't like it he would buy it back.  How could I refuse such an offer?

Once I received the SE upgraded LS-10 I let it cook for a long week  to give the new 240v transformers some burn-in time.  I started listening finally on Mother’s day.   My wife told me that she and all the women I love (mother, mother-in-law, sister-in-law) would be leaving the house to have their own celebration.  That was the second blessing.  I switched everything on and started my listening session bright and early at 9am.  David is not stretching the truth here folks.  The Upgrade Co. Signature Edition LS-10 took off to new heights and fathomed depths I thought were mere reviewers’ hype.  I heard things in the music  that had gone totally unnoticed for years.   My system finally came together:  ultra quiet background, incredible dynamics,  subterranean bass weight and depth, the purist highs and mids I have ever heard.  I was stunned that a preamp alone could produce such a major shift in the sound quality.

I have owned ARC gear before (REF1, LS3, Classic 60) and I have heard many other more recent and much more expensive preamps in my system recently and in friends’ systems trying to decide which one to get, and  I can tell you that upgraded ARC components can make real music.  

I stopped listening @ 5pm  to have dinner and resumed listening an hour later.  It was well beyond 10pm when my wife called to tell it had been three hours or so already.   The music just flows.  The sound is effortless yet extremely fluid and detailed.  Simply amazing that a preamp upgrade can make such a big improvement.

If you really want to lift the veils and hear all that Audio Research equipment can do, then send yours to The Upgrade Company. They will replace everything that is "For Profit built" with super top of the line parts and shielding….and that will be the start of a love story.  You won't find anything better. I sure can't.  I've continued A-B'g my LS-10 and I haven't yet.  The LS-10 design is now 16 years old yet upgraded it performs better then the new ARC preamps, and better then any preamp have I have heard anywhere.  Extremely ripe and full yet crystal clear and highly informative and detailed.

Don’t  just take my word for it.  You'll never believe this unless you heard it for yourself.  Give David a call  and see to it .  I can guarantee that you will not be disappointed.  Upgrade Co will buy anything back so you have nothing to lose really.

I'm sending Upgrade Company my AYRE C5-xe CD player next!
