Synergistic Red Fuse ...

Yes, it would help LAK. I know as I bypassed the fuse in a CEC transport and it improved the sound nicely.  A better fuse will also help as it approaches bypassing a fuse altogether, just not quite as good. 

I too have drank the Kool-aide, and installed a SR Black fuse into my Playback Design PDS-5, and two into my Veloce battery powered line stage. I have around 36 hours on them, and I can verify everything that Charles and Frank have claimed...my digital computer music now sounds more analog like; I'm hearing better details, subtle cues I never appreciated before, a fuller sonic density, and an overall much more pleasing sound quality. I have not yet tried switching directions, I am hoping I got it right the first time, but will perform that experiment after they are more fully broken in. Just another satisfied customer, grateful to follow on the backs of these pioneers who have alerted me to a relatively inexpensive tweak, that has exceeded my expectations in better sonic results..

Bob,how can a fuse in your battery powered preamp have any effect on sound quality if the pre is off the ac grid? Are the fuses connected in the dc circuit somehow? 

Bob ..

Glad you took the leap into the "Black" world of fuses. You're going to have to put another 30  hours on them before they really start coming alive, at which point the improvement they afford is mind boggling. Considering the price, and the fact that there's a 30 day return policy, it just seems to be a no brainer to me. 

As I mentioned somewhere else on this site, I've been in commissioned sales for over 50 years. There's a sales technic 

^^^^ There's a sales technique known as "The Puppy Dog Close." It goes like this ... Pet store owner: "Oh so you're undecided on whether you want to own this puppy? Well then ... why don't you take the puppy home for 30 days just to see if he/she would meet the needs of your family and fit in?."

Of course by the time the 30 days are up, you're so much in love with your new puppy that you wouldn't even think about returning it."  The SR 30 day trial on all of their products? A great puppy dog close. The products are so good, I don't imagine they get many returns on anything they build.  

Next up for me after three more BLACK fuses are installed into the system, is one of SR's wall sockets. Based upon what Charles says about what an upgrade this wall socket is, I just can't pass up that kind of improvement for a modest outlay of $95.00. 

Happy listening ...
