Marantz

I am a big fan of the Marantz since I have three models.

They take on a significant improvement when the power fuse is replaced with a Synergistic Research RED fuse. The SR RED fuse comes with a 30 dail trial. This is time well worth spent.

Plus you get to take the top off your player and see the beautiful layout and workmanship of your unit.

I hope everyone reading this thread will get that darn lid off, and at least replace the main power fuse. It is the fuse off by itself. The Marantz units really do respond to putting in a Synergistic Research "Black" fuse.

Your out of luck trying to replace the main power fuse on the Marantz SA11-S1 as it is hardwired into the unit. But you can try a WA Quantum chip ($6.00 ) placed on the fuse or try the Synergistic Research Electronic Circuit Transducers ( ECT ) places next to the fuse. My  Marantz unit has the WA chip and seven of the Synergistic Research ECT's inside. I did replace the five rail fuses with the Synergistic Research Black fuses. 1.6 amp, small, slow blow. Each fuse location did make a sonic difference but I did not try to establish which location made the greatest difference.

This unit really sounds good after these upgrades and they are removable if you sell the unit.
