Audiophile Fuses

I am someone who likes to make only one change at a time and live with each change so that it becomes my new baseline before I make my next change. As some of you might know from another thread, I recently changed my preamp from a BAT VK 30SE to a VK32 SE, which was a significant and surprising step forward. I then replaced the 6H30's with NOS 6H30pDR's and found quite a benefit, especially with regard to sound stage. Today I put one HiFi Tuning Supreme 2 A sloblo in the BAT and for reasons that I do not understand it screwed up the logic computer, that was fortunately fixed by resetting it. Instantly, I noticed one thing, the sound stage became even more open, especially front to back.
Not surprisingly there was an accentuated high end, which I attribute to the newness of the part and its connections. Fortunately, the harshness is passing very quickly, although I suspect it will take several days and at least 10-20 hours before I start to get any type of stabilization. So all I can say at this point is that little thing in the current path does make a difference!

I agree with Mr Astor on fuse direction. I am in the process of demoing the HIFI Tuning Supreme fuses in my Spectral system. In comparison to the stock fuse. The direction that offers a more extended top end should be the correct position. With the DMA-250 installing the fuse with the arow towards the amp has a more extended top end, dynamics, greater resolution, controled bass. The other direction rolled the top end, less dynamic, slightly deeper bass, less control. I have compared the HIFI Tuning silver star gold cap to the Supreme. The Supreme has a more extended top end and greater resolution then the Silverstar in my system. The two 5 x 20 mm one amp slo-blo fuses for the 4000S Pro CD Player and 30SS Pre are coming this week. I have allready found the fuse direction that sounds closer to the stock tonal balance for the 4000S Pro. The 30SS may require the direction reversed due to the power on switch/fuse position is down while the 4000 is up.

After about 30 hours of using a HIFI Tuning Supreme fuse in my preamp, things have smoothed out considerably, but not totally. There is still some brightness in the top end that I think is wrong. I say I think it is wrong, because maybe it was always wrong, but somewhat muted previously. After another 20 hours, I will reverse direction as per Myles' recommendation and then report back.
Curious: Has anyone reversed the fuse, then reversed it back to the original direction? I am wondering if the wiping action on the contacts, rather than direction of the fuse, is in play.

Hi all, I installed a HiFi Tuning Silver Star last saturday and upon its initial insertion I was very pleased with the sound, before installing it I cleaned the stock fuse on the main ac line on my Halo A21, which was incredible in an of it self. Then I also treated the Silver Star with the Caig pro gold, its been in the amp for close to about 120 hrs of Idle time and about 40 hrs of playtime and upon each listen it gets smoother and I like what it does that much more. Overall its very extended and grain free, quite background , deeper bass extention and faster transient attacks, with out sacrificing the space between instruments and has made for a very nice 3d presentation. I'm very intrested in the new Supreme for the rest of my fuse replacement , but wondering if its to detailed over the Silver?
I'll throw in a little story ... (oh no!!)
Chap was trying to lift up a car engine with a chain, but no matter what he did the engine didn't move ...
Neighbour wanders over, and says, "Getting anywhere?"
"No, it's a mongrel! The chain seems to keep stretching and it's not happening! But, I'm pretty sure that the second link on the chain is not right, so I'm working on making it better."
"What have you done so far?"
"Man, I've sent that link away for heat treatment, put in one twice as thick, turned it sideways so the long sides take the strain, I hear you can get ones made over in Russia that use material developed for rocket engines, there are so many options!!"
"What about those links further up, made out of elastic, and that one there, using a couple of bits of fencing wire?"
"Nah, that's how the chain comes when you buy it, you can't touch those. No, I'll have to compensate by getting this second link here just, just right"

Hey fuse tweakers, I replaced the fuses in my Anthem processor last night with a Hifi tunning Silverstar and one gold becase the value was not avalible in silver, well to my surprise the result was not the same as the good results I got with my amp
. So off came the hood to try the other direction and it did sound a little better but now the bass was missing highs where more extended but an overall thin sound I was not willing to live with, before with the fuses in the other direction the sound was diffused highs a tad ressesed and sounding as though the bass was struggling to come through. As a last resort I called Anthem, which might I add has some of the best customer support on the planet! They pulled up the schematic of the signal flow and walked me through and whata ya know! one fuse heads one way and the other a different according to the flow! So back in the Anthem I go to change the fuses around, put it back together fired it back up and low and behold musical flow, extended highs, bass extention and a palitable midrange! So with an ostounding yes they do have a directional flow at least to my ears! many thanks to Anthem on this one.

Myles,
I owe you thanks for turning me onto the HiFi Tuning fuses and their directionality. I have tried the fuse in both directions in my BAT VK 32 SE preamp and while either is better than the stock fuse, by a considerable margin, you are right that positioning the fuse with the arrow on the logo in the direction of the current flow does make a difference, especially with regard to sound stage, which is the biggest change I hear with this fuse. In your experience, do you think that there will be comparable changes with fuse replacements in my new Bryston 4B SST2 and Bryston DAC?

Therein lies the problem. I got the 15 amp value and I need 0.6 amp for the preamp. I think I can exchange it locally though.
So I bought the hi-fi tuning fuse (silverstar) 1 amp for my phono pre (XP-25). I'm not sure if I hear a difference yet or not. I am auditioning a preamp currently so it probably wasn't the best time to do a comparo. Here's my take. Clearly these fuses are a superior contact point compared to the stock fuses. The fuse is like $60.00. In the grand scheme of things, in this case a $10,000 phono stage, I'm not going to lose any sleep over $60.00 and just may sleep better knowing I have maximized the quality of my connection with said component. YMMV. I also plan on using this fuse in my preamp. The power amps don't have fuses so no worry there and I suppose my Digital rig could benefit from these fuses. My Wilson speakers have fuses, so maybe it's worth a try using them there too.

your Wilson speakers have resistors not fuses
That's good to know....I guess some of the deep bass can get tuned out for very small rooms where bass overload is a problem. I had forgotten about the resistors and had mistaken them for fuses.
