    When reading about "add on" things that improve SQ so dramatically I always wonder why even high end equipment manufacturers make their kit so badly that such things are needed?

    If aftermarket power cables make such a difference why weren't the standard ones made to the same quality?

    If cables need grounding, or whatever, why don't the equipment or cable manufacturers tell you this?

    If cabinets pick up resonance why aren't they made more rigid and with decent feet on them

    People pay tens of thousands of amps, DACs, CDPs etc yet they're supplied with substandard power leads, aren't earthed properly have rattly cabinets and wobbly feet, meaning that the poor sucker that bought them has to spend more money to get them sounding their best.

    Imagine spending £400k on a Rolls Phantom then having to spend another £50k on new shocks, springs, tyres and extra sound proofing to make it ride properly and more refined inside?

    That reminds me of my argument about power supply upgrades or extra add-on power supplies. If they are needed, surely the equipment was inadequately specced in the first place?

    Exactly, I'd be fuming if I bought a high end amp and found the power lead wasn't top spec.

    You can buy aftermarket improvements to loads of cars, possibly not the RR Phantom, but some pretty expensive cars can be modded to improve various aspects of performance. Although I grant you that industry also has a fair number of 'upgrades' that do nothing (that can be defined in measurement).

    People like to tweak. So there's a market for it.

    Everything is built to a price, even cars have option kits.

    True, but they're fitted to the car before it's delivered and by the manufacturer or dealer not bought and fitted after delivery by the owner.

    Yes, most cars can be modified but usually to suit the owners taste. For example you can improve handling by fitting stiffer suspension but this compromises ride quality or get a remap for more performance at the cost of fuel consumption.
    In my opinion changing the power cable, and adding anti resonance feet/Damping to a high end piece of audio gear is akin to the Rolls Royce I mentioned before being delivered with rattling body panels, uncomfortable suspension and restrictive fuel lines, all of which would be totally unacceptable to expect the owner to replace himself

    A better analogy would be having the interior of the Rolls valeted. It isn't going to improve performance in the slightest but you are still going to feel better about it whilst driving it around.

    Not really, valeting isn't upgrading a standard part which, on a high end car, shouldn't need upgrading if it was made properly in the first place.

    There is a rather amusing review on the Stereophile website for the Nordost QKore grounding box. My personal highlight of the review is the advice from the manufacturer about keeping it off the floor and recommending using their ďresonant control devicesĒ under it.

    If itís that susceptible to vibrations why didnít they take this to consideration when designed it.

    Apparently even mixing the materials these feet/supports come in alters the sound!

    I honestly cannot see how any of these products could lead to improvements. Even if they did Iím sure itís nothing that couldnít be solved alternatively using basic grounding techniques at a fraction of the cost.
