    Super Mains CableI have a Teac Reference headphone system I use with Samson SR850 Pro headphones. I have upgraded the 1/4″ jacks with MG Neutrik and use MG Canare LV-61 interconnects ( these are superb, but seem to have been dropped from the latest catalogue – a great shame!)I was so satisfied with both these products & service I bought 2 DSP Black mains cables to replace the stock Teac reference OFC ones. The difference was immediate & very positive. A wider soundstage with better detail retrieval combined with a relaxed neutral presentation – very similar to the LV-61 interconnects infact. Highly recommended to replace yr standard “free” cables.

    Seriously excellentI have some of these powering various things like my digital filter and I must say they are simply superb. The build quality is fantastic. Gold plated plugs too. A superb upgrade in sound. Highly recommended.

    Lifting the veilI have had this cable for over a month now and I am pleased to add my praise for it. Straight away I could detect a difference, it was a bit like lifting a veil on the sound revealing a new layer beneath. The other thing I have noticed is a wider soundstage compared to before, much wider which is good for me as I live in a small flat and I can’t place my speakers as far apart as I would like to. The cable is very beefy and substantially made with a tight fit at the connection end. It wouldn’t make a cheap system sound like a high-end, expensive one but it should give any hifi set up a boost no matter what your budget. Recommended.

    An excellent power cable. I’ve tried some other well known brands (with 60 day returns) costing up to five times the price and these are giant killers. Very natural, musical and a great, deep sound stage. Very highly recommended.

    Black Series DSP 2.5 Dual Screened power cable.

    This is my thoughts on the Black Series DSP 2.5 Dual Screened power cable.
    My system gets it’s mains power from an Airlink balanced mains transformer. So I replaced the existing cable to the transformer with the DSP 2.5, there was very little improvement I thought, undaunted, I persevered, next the cable from the Airlink to the spitter board, bringing improvements to the sound. I felt that these improvements were being held back by the remaining cables that fed the individual components.
    The mains cables to the CD transport, tuner and amplifier were all replaced, this bought significant audible improvements in the overall presentation of the music. The cable to the turntable a Garrard 401, is yet to be replaced, although vinyl playback has greatly improved.
    The DSP cable improves after a few days, when first installed the bass is bloated, tightening up after a while.
    The DSP has replaced ageing power cables from the Lake District, and was worth doing. The improvement wrought, bely the cost.
    I thoroughly recommend this cable.
