    Nice one, Mark. In reference to the emboldened text, it's worth stressing that said fuse up-rating can be requested by anyone to their electricity supplier, and I've not known of a case yet (amongst those I've spoken to who've done it) where that request has been denied.

    Of course, as the main fuse is the property of the electricity board, it's their job to replace it, not you. I only did it on the say so of a qualified electrician, who's authorised to carry out that job on behalf of the electricity board, thus making the installation legal and above board.

    Incidentally, as I said, the electrician is a long-term friend of mine, whom I met when Del used to work for Wrexham council, where he is employed as a supervisor. He's top notch and really knows his stuff. It's the same chap I took down to Steve Toy's place, to sort out his mains set-up, as detailed in this old thread: http://theartofsound.net/forum/showt...ains+marco%27d The fact is, I've been doing this stuff for years!!

This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    for the people who know

    these fuses are from Germany...they are every bit as good as AMR fuses for a fraction of the price..gold plated ceramic body..just they haven't got AMR stamped on them

    http://www.ebay.co.uk/itm/1808961891...%3AMEBIDX%3AIT

    check out his other items..he has different value fuses too...

    incidentally..I have nothing to do with the seller other than..I have bought fuses from him and put them in my MF A3 integrated..and what a difference...

    Has anyone looked into how oxidation affects the physical and electrical properties of fuses? I wonder if one type of oxidation has a more radical affect than another and additionally I wonder if by cleaning the fuses that it's the removal of the oxidation that gives a perceived performance?? Just a few thoughts whilst pondering the subject.

    Yes I agree..my fuses and the holders were cleaned with bluehorizon contact cleaning fluid before I put them in...also a ceramic body plays its part over the standard glass fuse


    were cleaned with

    Have to say folks, I tried a Synergistic Research Black fuse just this last week. After reading the reviews, and speaking to my dealer (who is also a longtime friend) I had to try one. He has customers with systems that cost over $500,000 CDN, and they put in the SR Black fuse in amp or preamp and comment it is a better upgrade for them than a set of Nordost Odin interconnects.

    I have had this in my system one week now. I put it in place of a standard $5 fuse into my Air Tight ATM1-S tube amp.

    The results are astounding. Yes, it is a better upgrade for me than accessories I have installed that cost up to $5K. I am absolutely shocked. I went in expecting nothing. After all, just a fuse right and how can it make a difference?

    The biggest change is how "big" the entire system sounds, with crazy bass output/drive from my smallish Proac Response D Two speakers. Vocals have gone from thin to rock solid "you are there" realism.

    Every aspect has SIGNIFICANTLY improved with zero downside. Details, details, details... I am hearing so much that I never knew existed in my favorite tunes. Soundstage size and depth both received a big increase in scale.

    It is very expensive at $175 CDN, but it has made a bigger difference than going from a basic cheapo power conditioner to a $5K Audience conditioner.

    I have no idea why it works, but I would sooner give up my $2K interconnects than this $175 fuse.

    Not to say the interconnects and such do not make a difference. They do and it is good, but the fuse is a different matter and for me the most surprising upgrade I have ever made.

    I do not think the fuse will make a $500 amp and with a set of $500 speakers turn into a giant killer, but if you think your system is already fine tuned enough for you, be prepared to be very surprised.

    Well Paul, you've definitely tweaked my interest. I am quickly reaching the point that Ive not much else to try, perhaps I'll take a stab at it? But which would be the most important to try first? The amp? Or Preamp?

    Hi Russell. I don't know actually. I went with my amp over my preamp on a hunch. I did not ask my dealer which he thought would be best, I just assumed the amp might benefit more but I could be wrong.

    The sound continues to improve. Synergistic Research quote 200 hours of burn in time, and I don't doubt it. The sound is changing daily. I am letting my system play even when not in the room listening to speed that along. I have maybe 100 hours of play time on the fuse, but only about 20 hours of listening so a couple hours per day.

    I am getting more pleased by the day. The sound is so freaking natural and relaxed now, drifting further from a digital artificial sound to what I would classify as more analog, in the sense of turntable reproduction vs CD.

    I asked my dealer if I could put a replacement fuse in my Linn Akurate Kontrol preamp, and he said yes but I am going to wait until full burn in is complete. It sounds so darn good now, that I am not tempted to alter the "recipe"...

    Paul

    Exactly my findings too, have them throughout my system.
    To me, given that what eventually becomes your musical signal goes through the fuse, I see it as a fundamental part of the power supply.
