The SS78XX discrete voltage regulator has been reviewed in the CD94 Marantz CD player.

I always believe that a clean power supply is very important for audio. Once the power supply is quiet, we will hear more things. That is why I am in a quest for a cleaner power supply, which brings me to this product from Sparkos Labs. They are already getting attention with their discrete op amps, but the product that brings up my interest are their discrete voltage regulators.

It is quite straightforward to change the regulators in my Marantz CD player. I just need to unscrew 2 screws at the back panel of the player, unplug the cable from the circuit board, and take the heatsink module out. The 3 regulators that I  need to change are attached to the heatsink module. After some desoldering and soldering, I finished the installation of the 3 discrete regulators from Sparkos Labs. These 3 regulators are supplying the digital side of the CD player.

Now for the listening parts. Big difference! It improves the sound of the Marantz CD player in all aspects. It is so much quieter now and brings out more micro and macro details. More transparent with a good transient attack. Vocals are more fleshed out,  immediate, and palpable. Bass goes deeper and is punchier with a good decay. Cymbals sounded more realistic. It's more lively. I can feel the music. Much better emotions and expression from the singer. I can get the feelings and the energy of the band playing in front of me. This regulator is one of the best upgrades for my CD94 Marantz CD Player.

It makes me listen for hours now.

Kind regards,
Eddy.
