    "Impressive"
    Having used the mains superfuses to good effect I ordered 2 internal superfuses last week, one for my CD player and another for the amplifier I have to say I'm very impressed with the improvements. Maybe there's an accumalative effect with the mains superfuses!! My Audiolab 8200 CD player has always sounded detailed but now sounds even more detailed on familiar discs as well as all round improvements in bass quality, stereo imaging, treble sweetness and textures, worth every penny!!

    "Very Impressive"
    After using some of the mains plug Superfuses and being pleasantly surprised I bought a couple of internal Superfuses to try in my valve power amplifiers. Unlike lots of other audiophile fuses these Superfuses sound tip top straight away. Having listened to lots of Russ’ products over the years I would say that the ‘house sound’ is just a very natural, easy, musical one, and these fuses deliver that in spades. They have also removed a niggling high frequency glare that I was blaming my new listening room for. Room treatments didn’t solve the problem, but these very modestly priced fuses did, and without the need for a lot of ugly bits and pieces stuck around the room! Cheers Russ, I will certainly be getting a lot more of these great fuses.

    "Slow Blow Internal Superfuse"
    Tighter base, sweeter treble, less sibilance and more detail - what's not to like? This is the first internal SuperFuse I've fitted (to my Naim Nait XS Amp) and the improvement is clear. Not cheap but worth every penny!

    "Internal Super Fuse"
    I have these fitted to my CD player and amplifier. I am suprised at the extra detail and tighter bass compared with the original fuse. The sound is altogether 'cleaner' and sweeter than the original fuse. A very effective and reasonably priced upgrade.

    "Re Superfuses"
    I have been using another brand of fuse, but after trying one I have replaced main fuses and internal fuses with super fuses. I have to say that I much prefer the sound. I used to be a sceptic but after all the effort of dedicated supply, cables and plugs and supersockets it really is the icing on the cake.

    "Astonishing Upgrade"
    superfuses are even better when used from wall plug to equipment leads to internal fuses I was cautious/sceptical so did it bit at a time although it got quicker as I heard the results. I considered my system well sorted and at a pinnacle of performance so did my family. so think not expensive fuses but a real upgrade for a bargain price.!!!

    "Excellent Product With A Really Noticeable Effect"
    My system already has reference powercords fitted with Superfuses and I had already experienced their affect. Have just fitted the one in my cinema amp and WOW! Listened to a best of Billy Joel album that had previously been dct treated. First few chords and I was blown away. As other reviewers have said, the bass seems tighter and there is a lot more detail across the whole range.

    "I Would Recommend This Product."
    I have just fitted these to my CD player and intregated amplifier. These were already connected to the mains by Powerkords fitted with Superfuses. It was immediately apparent that the bass was both tighter and deeper. There was also an increase in detail across the frequency range. These improvements were very noticeable so any doubters should try these before forming an opinion.

    "Amazing Improvement"
    I've been waiting patiently for Russ to produce slow blow internal Super Fuses and so thrilled when at last they appeared. My SuperKords are already fitted with 13amp Super Fuses and so I know what they can do. My equipment is also fitted out with the excellent Russ Andrews DCT internal fuses and so I was really keen to see what the slow blow Super Fuses could do. I was not disappointed. Fitted into my cd player, straight from the first track I was startled by the improvement. More detail ' I hadn't heard that before', highly realistic portrayal of the musical imagery, sweeter rendition, particularly of string instruments. In short, splendid improvements all round. When funds allow I shall be purchasing more fuses for my pre and power amps. Can't wait to see what that will do for the musicality of my system.
