Fuses that matter.

In the past I have had stock , Isoclean, and Furotech fuses in my Art Audio PX-25 tube amp, and my Marantz SA11-S2 SACD player. In June I replaced these fuses with Synergistic Research fuses. Since these were the power fuses at the A/C inlet the equipment does not have to be opened to change the fuse. Simply pull out the fuse tray below the plug and change the fuse.
I was quite impressed by the improvement the SR fuse made. The 3-D sound stage was much improved. Detail was improved but did not favor one frequency range at the expense of another. The sound was more detailed but more relaxed. I did not experence listener fatigue.
As easy as it is to swap power fuses in most equipment and no risk to return the fuses, I think this is a fun and rewarding experiment most audio hobbiests will enjoy doing.

Fuses on the Marantz SA11-S1. The basic power fuse on this player can not easily be changed. It is hardwired to the circuit board. You can change the rail fuses by removing the top of the player. There are 5 fuses in the unit. 1.6 amp and 1.o amp. All are slow blow and size small. Each is clearly labled. I have changed the fuses to Synergistic Research on the SA11-S1 player and it does make a worthwile improvement ( even at $59.00 X 5 ).
The Marantz SA11-S2 does have a power fuse inside. You have to open the top like the S2 model. Inside the power fuse is labled 3.15 slow blow and easy to see and get to. It has 6 rail fuses. 1.0 amp and 1.6 amp. All small slow blow types. Just replacing the one power fuse on the S2 player makes a difference. Replacing the rail fuses makes a further difference.
The two amps I have replaced power fuses on are the Art Audio PX-25 and the Eddy Current Zana Deux amps. With these amps the power fuses are located in removable trays below the power cord socket.
It was easy to replace the fuses on all four products and all four improved in sound when the Synergistic Research fuses were installed.
E mail me if you want me to walk you through how to open a S-1 or S-2 Marantz SACD player. It is fun to get to look inside your own player. It helps demystify the equipment.

I use the Synergistic Research fuses and I think Audiolabyrinth will find the RED fuse to really increase the musicality of his system.
I found it to be a fun and rewarding experiment with no downside.
