Started off buying three 13 amp SR20 fuses second hand from a member here. Pleasantly pleased with the performance of these for the price. I put one in my mains block plug, one in my TDAI3400 mains lead and one in my Rel Stentor III subwoofer mains lead.

Overall the system sounded slightly more relaxed, and tighter focussed , a worthwhile investment but not ground breaking.

Inspired by the discovery that fuses can make a difference and after reading some threads i decided to take the plunge and try the newer and significantly more expensive blues at £130 each.

To be continued.
