I have had much success working with David and the Upgrade Company for going on 2 years. David has performed upgrades on quite a large number of my components including CD/DVD player, Blu-ray player, Pre/Pro, preamp, many amps, DAC, and Power Conditioners. Yes the upgrades do make decided improvement in performance. Besides just replacing parts, much of David's efforts are in controlling noise. He will generally work on damping and vibration of the machines as well as incorporating filters. He replaces parts in specific areas of the circuitry design, installs better RCA connectors, and generally an IEC inlet if it is lacking in the original design.
To show how much faith that I have in David's work, I am purchasing another pair of Aragon Palladium 1K monoblock amps and one of the pair is being sent off for upgrade to match my other 4. The 6th one will be used as a back-up.
If I can be of any more assistance and you want particulars for the equipment please let me know.
