Hi-Fi Tuning Fuse for NAD C352?

I owned the C352 for a short time and I've used those fuses on several pieces of equipment. Bottom line is it isn't gonna be a noticeable improvement for you! Maybe on ARC reference gear or Krell/Levinson/Mcintosh etc...not on an NAD C352! If you can get a Krell 400xi even, maybe then you would notice improvements, granted your front end and speakers/cabling is up to snuff.

Believe me I KNOW the urge to try and improve a system! Sometimes what we have is good enough...at least for now.
