“I have been a customer of David Schulte and his Upgrade Company for over 10 years now. Over 10 years ago, I had a Marantz SA-11 SACD player and a Marantz PM-11 integrated amplifier in my stereo system and was quite pleased with their music delivery. Upon reading some positive reviews of the Upgrade Company and David's work, I sent my 2 Marantz units to David for his Signature Edition upgrades. David transformed the 2 Marantz components from excellent performers to giant killers with his SE upgrades. Fast forward to a year ago. I decided to upgrade my A/V system and consolidate all my components into one system. I purchased a Denon 3313UD universal player and Denon X7200WA A/V receiver with Signature Edition upgrades from the Upgrade Company. These SE upgraded Denon units far exceeded my expectations for what components at their respective price points are capable of. Smitten, I replaced the Shunyata Anaconda power cord feeding my entire system with a TimePortal Signature power cord from the Upgrade Company. I was floored by the improvement that the TimePortal power cord brought to my system. I was hooked. So 3 months ago, I replaced my Shunyaya conditioner with a RGPC 400 Pro power cell with SE and Furutech upgrades from the Upgrade Company. Once again, this upgrade elevated my system to a whole new level of performance. I was able to demonstrate that each successive upgrade from the Upgrade Company has brought me closer to that ultimate live experience. I can say with confidence that the Upgrade Company's SE upgraded components far surpass the performance of other manufacturer's well respected stock units which cost much more. Before closing, I will share my most recent experience with David and his Upgrade Company. A week ago, the disc tray in my Denon player would not open. I called David and he asked me to send the unit to him for troubleshooting even though he was living out of a hotel in the midst of his relocation to Nevada. Upon receipt of the unit, David immediately looked at it and fixed the problem by performing a hard reset procedure. This is a testimonial to David's commitment to customer service. In closing, I will say that unless you are prepared to spend a fortune, the Upgrade Company is the most cost effective path to maximize your hard earned dollars to obtain top notch performance.”
