Marantz SA11S3

violin:

The Marantz SA11-S1 does not have a user replaceable main power fuse. It is hardwired into the circuit. It does have a total of 5 rail fuses that go to each subsection of the player. The player sounds better with these fuses upgraded. You can replace them one at a time.

Your Marantz will sound better if always left on. The DAC chip - circuit takes a long time to 100% stabilize. Antelope brand DAC's used in the recording studio are always left on, as even a broken in unit will take three days to stabilize.

Marantz equipment responds very well to fuse upgrades, especially to the Synergistic Research Black fuse. The system improvement I believe from this fuse is greater than going to balanced cables. Been there - prefer unbalanced in my Marantz systems.

If any Marantz users are still using regular home construction wall outlets, I hope you will try either the Furutech GTX-R outlet or the Synergistic Research Teslaplex SE outlet. Both will allow the Marantz players and amps to reach their full sonic potential. The Synergistic Research outlets are less costly and sold with a thirty day money back trial.

Marantz makes some great equipment - enjoy.

Actually, replacing a fuse with a better fuse makes all the sense in the world.  How much do we spend on power cables? Yet it all goes on through a 10cent fuse, please.... It makes perfect sense and SHOULD make a difference.  I would have replaced mine long time ago.  I just cannot get the damn lid off

Our audio systems are links in a chain. We would not want any weak links (at least I do not).  Happy Listening!

How do I use the flat screwdriver to pry it back.  Do I install screwdriver in the back where there is are two lipped areas?

Any comparison to the DV-9500/9600 ?
