Synergistic Red Fuse ...

Zacho,
Hello and welcome to this very fun and friendly thread. I’m not familiar with your components but can’t imagine why you wouldn’t derive noticeable sonic improvement. Here are a few examples.

My system, Coincident electronics(Line Stage and 8 watt SET amplifier ) and speakers.
Friend #1,Absolare Passion  preamp, Krell mono blocks and Rockport Altair  speakers.
Friend #2, ARC Preamp and amplifiers with Martin Logan speakers.

Three very different audio systems (and rooms) yet we achieved the same level of improvement using the SR Black fuses. If you have read much of this thread you know that the response of users has been exceptionally positive for many of them.

If you do try them let us know your listening impressions.
Charles,

Good grief ... the fuse change in the amp has brought the system to another new level. The Black fuses are so far superior to the Red fuses in my system that for the small amount of extra money in cost, there is no reason not to buy the Black fuses. 

Tonight was a Harmonia Mundi night. We know how great these recordings are ... but the instruments are so clear and three dimensional now .... like never before.

With the new fuse change, its reach out and touch the performers time.  So much more air around instruments. The system plays much larger now too. The room is filled with sound. There's wall to wall imaging and more front to back depth. 

I have no way to scientifically test these results, nor do I care. I let my ears do the testing for me.   Speaking for my system only ... any owner of ARC gear who hasn't converted over to the SR Black fuses, hasn't experienced what ARC gear is capable of. Simply amazing. 

Robert said it best last night ... "Spectacular." 

OP

OP, have you considered bringing home a Ref 6 to try?  You appreciated the upgrade from the Ref 75 to the 75se.  It is a much larger upgrade than that.  Simply a stunning upgrade.

oregonpapa:

That was a wonderful five sentence description of the effect the Black fuse has on a system's sound. " The room is filled with sound" - like oregon papa, my system now has this quality  with the Black fuses in place.

It really makes the music and the artist's performance take on a very emotional experience. No longer is the music just " over there ". Now I am surrounded and immersed in the sound.

Zacho - The Singapore voltage will not be a problem with the fuses. I do think you will hear a wonderful improvement with the Black fuses in both your amp and DAC. I hope you will try the fuses. I certainly am glad that I did.

Regarding the fuse upgrades Zacho is considering, if the fuses involved are AC mains fuses, and if they are the smaller of the two sizes SR provides (5 x 20 mm), I'm not sure I would feel comfortable using one of those fuses in a 240 volt application.  The SR 5 x 20 mm fuses are rated at 250 volts, which doesn't seem like a lot of margin relative to his line voltage, considering also that I wouldn't assume such specs to necessarily be precisely accurate.

The larger 6.3 x 32 mm fuses are rated at 500 volts, which would be fine.

None of this will matter under normal operating conditions, btw.  The only time the fuse will "see" the line voltage, and hence the only time the voltage rating will matter, is when a fault in the unit necessitates that the fuse blows.  If the voltage rating is inadequate, relative to the line voltage, the fuse may not "open" properly, and may continue to conduct current.  Or, conceivably, it may explode.
