Hi-Fi Tunig Fuses & Parasound A21

FYI  The Parts Connexion has a sale on HifiTuning Fuses going on now.  I am awaiting the arrival of four silver star fuses.  They were 60% off!!

I blew my hifi-tuning gold rail fuses in my Revision A+ of my McCormack DNA-1. MY bad.  After calling Steve McCormack he discussed his preference for the silver star over the classic gold and supreme fuses.  He was disappointed that Hifi-ftuning stopped producing the silver star in favor of the supreme fuses.  He tried the supremes on two separate occasions and just did not get the openness and clarity of the silver stars.

After speaking with Steve, I googled silver star fuses and fortunately, Parts Connexion had them in stock at 60% off!!  Instant order.  In the interim, I procured Bussman ceramic body "microwave" fuses so I could listen till the silver stars arrived.  The Bussman weren't bad in the sense that I had music but the subtleties were MIA.  The sound was "matter of fact".

The fully run-in Silver stars have really opened up the soundspace.  There is "space" between and around instruments allowing each contributor to shine on each cut.  Great stuff.  Steve knows his stuff.

Like most anything that impacts the electrical circuit of a piece of kit, break-in is necessary. Obviously this requires patience, a virtue few of us in this hobby possess in abundance. I don’t have an electrical engineering degree that might help inform me as to why things in this quizzical hobby happen as they do but they do occur. There is plenty of anecdotal evidence of such all over this site. Perhaps the mystery is part of the appeal.

As far as Steve McCormack goes, I know what my stock amp sounded like and what it sounds like post SmC Audio mods. Nuff for me!
