ARC REF10 fuse upgrade


I'm interested in upgrading the fuses in my equipment to HiFi Supremes.
The problem is that my ARC Ref10 preamp is using a 6.0A fuse from the factory, and the only option is the HiFi Supreme with a value of 6.3A.
Will there be any problem with this 0.3A difference?

I think it is unwise to replace any fuse with anything other than one with the original value.

It should not be a problem as long as it is within 10% of the value. The Ref 10 should have at least two fuses, look on the circuit boards. I have a Ref 5se and it has two fuses. One on the back and one inside on the circuit board near the power supply.

I replaced the fuses in my Ref 5se and Ref 110 with black Supreme HiFi Tuning fuses. To Be honest I really can't hear much of a difference. I did not replace the fuses in my other ARC pieces. I have heard them make a positive difference in other pieces of gear just not my ARC pieces.

What did make a huge difference with my Ref 5se was power cords. It was amazing how much of an effect they could have. The Shunyata power cords were a revelation, like you took a blanket off the speakers. If you have not played with power cords I would suggest you give them a try. I heard the biggest change with the preamp power cord but they all made a noticeable difference.
