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.

Various System with Signature Edition Upgrade

About 5 months ago I was ready to invest some more $$$ into my system to improve both my vinyl and digital front ends.  

I purchased an Upgrade Co. SE Upgraded Audio Logic 34MXL Tubed DAC complete with NOS Black Gate F, N electrolytic capacitors and top of the line MunDorf Silver+Gold+Oil output coupling caps and had the silver+gold MunDorf wire swapped in and WBT Ag NextGen RCA sockets and Neutik silver pinned XLR sockets installed, and Amperex NOS tubes, and finished off with Upgrade Co’s RFI EMI riddance technology, and chassis dampening and new EAR footers.  Figured I got 30 day return period if I didn’t feel it was worth $4k.

Picked up a TimePortal Statement SPDIF RCA Silver Digital cable to feed it from my SE Upgraded Oppo BDP-105 player’s coaxial digital output.  I was truly blown away.  It just killed my previous vinyl LP rig.  What really blows me away is that over the past 4 months the DAC and digital interconnect have continued to gradually increase in performance as all the new caps, parts, wiring, & NOS tubes continue to burn in and “season”.

After the DAC I couldn’t stand to turn on my vinyl setup it just sounded like crap so I called David at Upgrade to see what he suggested.  David suggested I start with a Millennium Carbon Fiber LP Mat ($399) to absorb RFI EMI before it’s collected by the metal wiring and cantelever in my MC cartridge, and a new SE Upgraded tubed EAR 834 Deluxe Chromed MC/MM phono preamp with Telefunken NOS tubes and VCap capacitors and Upgrade Co’s RFI EMI Riddance Technology installed throughout inside.

I had a Project Tube Box phono stage before and let me tell you that thing sounds like a little toy, an AM radio, in comparison.  I didn’t expect such a tremendous improvement.  Then a couple months ago I got the itch to further improve so I ordered a new set of Nordost DIN-RCA plug-in tonearm cables for the SME-V tonearm to replace the stock Van Den Hull DIN-RCA Cables.  Wow that kicked everything up again.  Digital is better on some CD’s vinyl better on some good albums.  Now I can now play the crappiest CD’s and vinyl albums and enjoy it.
Always musical smooth no nasties great bass & highs & dynamics and 3D soundstage very organic and live sounding.

Everyone that hears my SE Upgraded system (w/ stock Legacy speakers) is amazed.   

I can highly recommend stepping up to an SE’d DAC over a 1 box player, the maxxed our EAR 834 Deluxe MC phono stage, and the Millenium LP Mat in addition to my previous SE upgrade testimonial recommendations.  

Shockingly phenomenal results.

David,

Please feel to use this testimonial on your website if you so desire.

A few years ago I decided to take the plunge into the 21st century world of iPod audio.   Being an audiophile type, I was concerned with the quality of sound I’d get through my main audio system. To make a long story short, I called my audio ally, Mr. David Schulte, to see if he'd had any suggestions. I’d been working with David for over 4 years at that time starting with my Mark Levinson No. 380S SE upgrade transformation which turned out fantastic, so I trusted his judgment on subsequent purchases.

About 3 years ago David recommended an upgraded Wadia 170i iPod dock, combined with an Audio Logic 34MXL tubed DAC Upgrade Co. had just finished upgrading with a plethora of high performance parts, MunDorf silver/gold wiring, WBT silver Nextgen connectors, fancy silver XLR connectors, dampening, Black Gate & MunDorf capacitors etc and applying their proprietary shielding/attenuation/dissipation/dampening technologies which are similar to what’s done in the military/space arena to the insides of $30+ million dollar space satellites to block out and dissipate RFI & EMI energies.

I’ve been very pleased with my new found iPod capabilities through the SE upgraded Wadia and Audio Logic combo. Fast forward about two years later, David contacts me about some other equipment I might be interested in, and in passing, mentions that he can significantly improve the performance of my “classic” Audio Logic DAC for under three hundred dollars, their typical “update fee” to bring their older upgrades current with a new guarantee that it will beat anything that has not been SE upgraded by Upgrade Co.

I didn’t know how much improvement David could pull out of this older unit, but he assured me they could dramatically transform it further due to ideas and techniques that were not available when I bought it. I’ve never doubted David, so I sent in my Audio Logic 34MXL to have another round of upgrades applied. I only expected to hear a few little improvements at best, but in true audiophile spirit, I told myself any improvement would be a welcome addition to my system. My big Rockport speakers really show what’s going on upstream in the electronics & cabling.

As usual, David’s people got right on my DAC and had it ready to go in no time. When I received it at my house, I had no idea what I was in for while hooking the DAC back into my system. The improvement in the sound quality was utterly shocking! I’m not someone to be a drama queen when describing audio equipment, but I couldn’t believe the sound quality I was getting from my iPod sourced music stream. There was much more detail, way better soundstage, a much more musical presentation.

And this was from a $300 update off an iPod source.

I've lugged my SE upgraded electronics to my audio dealer's showroom and I am not missing anything over much more expensive gear.

In summary, The Upgrade Company continues to deliver fantastic value for dollars spent. This is not the first time David has recommended further upgrades for equipment he’s already SE upgraded for me because as the years have gone by, their RFI/EMI riddance techniques have gotten even better. Each time David has come through on his claims, for a very modest “update” price. You can count me in as a repeat customer after doing nearly 7 years of business with The Upgrade Company.

In my opinion, David Schulte is one of the best technicians and businessmen out there. I’ve thoroughly enjoyed our numerous correspondence and business dealings. I don’t know how David makes time to deal with all his customers on a personal level, but he does a wonderful job of it. I can’t wait for the next opportunity to get another new toy from David’s workshop.

Sincerely,

Warren Hingst

U.S. Air Force Major, retired
