NAD C521Bee, C525Bee CD Player Upgrade

On and off for the past year or so, I have been upgrading a couple of old cd players by improving the power supply and bypassing the analog gain section that amplifies the basic digital to analog chip output musical signal (a preamplifier gainstage built into the player). In both cases, improved sonics were noted. It turns out that the main culprits causing the "CD" sound are the recording, the power supply and the cheap analog gainstage parts which cost approximately "$5.00" or less. Gain is lowered, but only approximately 6db, so 2 volts before results in approx 1v after upgrade. Almost all stereo systems have way too much gain anyway, so one can now turn up the volume control.

I recently, recently had the opportunity to upgrade a NAD C521Bee cd player. In stock form it is a thin sounding player. I know for sure that I would not have it in my system. However, when I opened the lid and found Burr-Brown ICs and separate digital and analog regulated supplies, I new the NAD had potential. Well, after performing some upgrades, including Cardas Rhodium RCA jacks, it now sounds "fleshy" with great tonal balance, dynamics, incredible soundstaging and depth, right up there, if not better than the much more expensive players. I then upgraded a C525Bee player and obtained the same beautiful results.
