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.

Primare CD-31 CD Player

Dear Mr. Schulte,

Hello. You modified my Primare CD31 almost a year ago and I wanted to express my appreciation. Awhile back, I took the upgraded Primare CD31 to the local A/V store where it was originally purchased. We did a comparison with a demo CD31 in the store. The sales staff were very impressed with the differences. One of them commented that the two of them "didn't belong in the same room."

The comparisons convinced me it was a very good decision to get your Signature Edition upgrade.

Thank you,
David La May
