Rewiring Acoustat model 3 speaker?

Hi everyone,

Since the last 21/2 years, I'm a proud owner of Model 3 Acoustat loudspeaker.

I just bought new speaker cables to drive them. So between my Krell KSA-150 and the Acoustat, I bought a pair of "MIT MH-770 Reference" (huge cables). (sound is spectacular).

To connect them to the speakers I change the bannana plug for good binding post to receive the spade of the cables.
I replace them with WBT-0730 binding post.

Now the first question. When the transformer was open, I realize that the cable inside was so small. Did the sound will be really improved if I redone all the inside cabling with good Van Den Hul cables? (or any cables suggestion)

Second question, inside the transformer, one of the cable connector pass by a tiny fuse. Did this fuse is really important?

You know when you buy so huge speaker cables and they are connect to so tiny cables inside the speaker, many questions goes on your mind.

Thanks in advance for the information. May 4, 2004.
