Fuses in the 3 speed SME PSU


I have a model 20/2 table serial # 1173 and wish to upgrade the PSU with Hi-Fi Tuning fuses. There are 3 in the unit and my question is, which of the 3 are most critical to the performance of the unit as I cannot afford to upgrade all at this stage.

Unfortunately there are MANY here who just refuse to even believe a fuse can make a difference never mind actually try them.
Full rack of SR Blue fuses and Duplex.
Might not upgrade to the Orange But you never know......
I agree nothing wrong with Buss fuses. Nothing wrong with Littelfuse fuses, either, they just sound very good, that’s all. It’s not a capital offense.
If you don’t hear the difference, consider yourself fortunate you don’t need to spend the money to upgrade fuses and buy more music instead. No one need to have "golden ears" to enjoy this hobby! 
Could be my ears, or maybe all my electronics have well design power supply no need upgrade fuses to sound its best.

>>>>The problem for fuse skeptics is everybody hears a difference. It’s hard to argue with 100,000 who can hear fuses. Well, except for a few outliers. Congratulations on hVe one of Have you considered getting your ears candled? 🕯
I'll never spend the prices SR charge. But I do agree that fuses make a difference. I tried a $40 Furatech rhodium but it was too bright/steely. 
Try this. I've done it and was amazed at the improvement. 
Wrap a few turns of masking tape around the glass part of the fuse ensuring it does not touch the metal caps. 
Worst case, it may indicate if the PSU responds to fuse adjustments.
