Hi Fi Tuning fuses

Yes, I know your position and your defense of RG, your hero, that’s why I included ramtubes among the mossbacks. If you’re an agnostic the question is why? How can anyone be neutral on the subject of fuses or fuse/cable directionality these days. Laziness? 😃

Meeeooow!

All I have to do is type the word lazy and Joy Boy shows up.

@OP, 
As you can see, this topic brings out 'the best' in people. Try not to get discouraged.
As far as Hifi Tuning fuses, Steve McCormack believes they do improve sound quality.
As for Ayre, and Levinson, I would call them directly and get their take on it. 
I only own Ayre equipment, but my experience shows changing fuses to have negligible effect.
