    I have bought several products from MCRU and each has added quality to my HiFi and AV systems. I never thought I would spend £40 on a fuse, but David explained that he offers a 30 day money back guarantee and has never had a Synergistic Research Quantum fuse returned. I have a science research background and was convinced a fuse cannot make a difference to sound quality. I fitted the first of these fuses to my DAC and amplifier. Immediately I noticed a broader soundstage and clarity. I ordered a further fuse and fitted it to my AV receiver. The change was a massive improvement in sound, much more so than the HiFi. Perhaps it is because the HiFi is high end with less room for improvement.
    Hence the Synergistic Research fuses improve sound quality across the board, but it seems some systems are improved more than others. I cannot even begin to explain why these fuses make such a difference, they just do. I am going to order a couple more and am now completely addicted.
    Give them a go, safe in the knowledge of a 30 day guarantee. I must be impressed, this is the first review I have ever bothered writing for anything!

    A step closer to real music

    I’d already upgraded my mains leads and added a balanced power supply. When I upgraded six fuses to the SR20 – the plug from wall socket to bps, from bps into Tacima 6-gang conditioner & RFI filter, Heed CD transport, DAC, integrated amp and outboard PSU, the improvement was immediate, easily discernible on any CD, and I was going through my collection again.

    Pitch resolution throughout the frequency range improved, making it easier to follow the notes played on each instrument. There was more resolution on complex passages, and nicely-recorded acoustic instruments became even more open. Bass was firmer and more tuneful; and the effect on cymbals was a little like a tape head had been cleaned. Transients were crisper, yet reverb was more audible, and I could hear low-level detail that I had missed before. On quiet passages on Seventies albums such as Van Der Graaf Generator’s Godbluff, the mains hum and tape hiss on the recording was more evident, but outweighed by the improvements to the music. In summary, the changes were all for the better, taking me closer to the live performance, and probably on a scale nearer to upgrading all mains leads rather than any one of them.

    “I’d previously used AMR fuses and they are well worth the expense but following an accident when I managed to blow a couple I read around the net and these ones seemed to be causing quite a stir. As much as the AMRs were a significant improvement over ordinary fuses these were a large improvement over them. Basically there was more of everything but the one area that stood out for me was the bass. The sound stage was much more precise. Using Magneplanar SMGa’s you always get a large sound stage but the focus is now very good. One aspect of the fuses that you should experiment with is directionality. It is certainly noticable with one being noticably forward and the other more relaxed. According to opinion on the web they take about 200 hours to burn. If you are tight on money then the AMRs are a good option but if you can afford these you will not be disappointed. Good enough for me to order a couple of the Reds.”

    “I must admit to being rather sketical about the SRS fuses, as a qualified ( and practicing) electrical engineer I have already installed a dedicated balanced mains supply along with Vertex mains block and mains cables, so I thought I had gone pretty much as far as could on the mains input side of things, but knowing could return them decided to give them a try and ordered 3 fuses. To ensure a fair test I cleaned the mains plugs and sockets with Deoxit and carried out a listening test before changing fuse in amp first……..How wrong I was!!!! The immediate impression was of a wider soundstage, more space around instruments this continued after extended listening. Next up the CD player /DAC again a significant improvement with the micro details that were always there but were now clearer and identified, can’t wait to try in my Whest phono amp!!!!

    If like me you’re a bit skeptical give them a try what can you lose, but like me you will more than likely gain for a relatively small outlay.”
