Where should I put a Syn. Orange fuse to try?

That's singular, not plural. So, if he can afford to completely refuse his system all at once, then sure, put them everywhere.

If he buys them one at a time, then I’d say put it into the preamp because every other component connects to the preamp.

I spewed coffee all over my monitor with that one., *lol*

I’d go with the preamp first ... and then the amp.
