I have Marantz SA11-S2 which has been improved by tweeking.
1. Replace the stock fuse at the A/C inlet with an "audio grade" fuse such as the Synergistic Research RED fuse. Easy to do and an immediate change in sound.
2. Order two 5 packs of the Synergistic Electronic Circuit Transducers (ECT) and place inside the SACD player to decrease electronic noise. The Synergistic Research website has suggestions on places to try thr ECTs.
3. Try a different power cord on the SACD player.
The above Synergistic Research products are sold with a 30 day money back trial. The "audio fuse" and the ECTs can be removed and placed on a new piece of equipment when it is time to let your Marantz unit go.
