Blue Fuse for Primare Pre32

That's a 2 amp slow blow fuse rated at 250V. 250mA would be too small a rating. You should get the exact rated and sized fuse that you currently have. Not go bigger or smaller as rated and never go fast blow in place of slow blow or visa versa.

As a side note I just recently replaced my standard fuse with a SR Black and was very impressed for the money spent. The Blue came out about a month after getting it.

What changes impressed you?

Took a good 75 hrs to break in for starters. What impressed me the most was a slightly better control of the music overall. Kind of like moving up to the next level of power cord without the huge expense. To verify what I heard I put the stock fuse back in after a good 200 hrs and I lost the 'control'.

That said it wasn't earth shattering but a nice improvement for $129.
