Hi Dave:
I am so glad I followed your suggestions. Your are a real gem in the Audiophile hobby: honest, credible, and genuine in your advice. In a hobby full of companies trying to rip us off, charging mega bucks for cables, tweaks, snake oil, isolation platforms and etc. YOU ARE THE REAL DEAL! I will never ever purchase gear without you adding your magic to it again. I was initially in the market to purchase a separate preamp and amp to replace my DK Design MK II Integrated Amplifier. Hearing some very expensive separates in my home caused this "upgraditis". When listening to my stock DK Design MK II Integrated Amplifier, something was missing. My system sounded good, but was lifeless and could not convey the soul of an artist. Listening sessions began to turn into a science project (Dissecting problems). But I am so glad I stumbled upon you by way of Audiogon and Google. After reading many excellent customer reviews, I decided to give you a call.
To make a long story short: Only thing I can say is WOW!! This amp is truly amazing now. You have transformed my system to something really special. My wife, who is not an audiophile, hears a huge improvement, stating "Oh yeah... it is way clearer". I will not bore you with audiophile jargon to explain what I am hearing because I'd like to get back to listening. Only thing I can say is "live in concert" in my house @ 8:00 PM sharp, the first act, Jonathan Butler "Surrender", next Miles Davis "Kind of Blue" . We (My wife and I) can finally enjoy our music time. Matter of fact, I find she is listening more than me now!
Thanks again,
Ron Barriere

PS - I tried posting comments on Audiogon several times, but none of my posts were let through by Audiogon. I may have to take another approach. They are not letting me express my views.


The Upgrade Company has thousands of brand new rare and patented Rubycon "Black Gate" capacitors in stock. Black Gate capacitors are considered "State of the Art" & "The World's Best" electrolytic capacitors, but too expensive for manufacturers to use.
