I have a Unitiserve ripper/renderer with a dedicated Teddy Pardo power supply. Obviously the purpose of the dedicated supply is to improve performance by removing the influence the power supply might have if housed within the unit. The question is - do Shunyata cords still help in this situation (i.e. adding an alpha digital e.g. to the Teddy Pardo)? I am assuming so since noise could still be passed on through this device and I don't think it has a filter or anything. Just curious if any one here has had specific experience with this question. And would it apply more or equally to digital or analog components with a dedicated power supply.
Hi Paul,
FWIW, My experience the past 18 years has been that yes, well designed power cords do make a demonstrable difference/improvement whether an outboard power supply is used or not, especially anything associated with digital architecture and signals.
To use a more benign analogy, top pre-amp manufacturers who design meticulously engineered outboard power supplies, such as Emmanuel Go of First Sound or Ken Stevens of CAT, readily acknowledge that a good power cord will improve their product's performance, as do a host of other electronics manufacturers who test these things. Pre-amp applications are not as sensitive as digital applications yet still, the benefits are very apparent (I've owned both preamps).
Very intense fields of EMI and RFI surround all electronics systems. Good power cords will invariably provide a very noticeable improvement in performance. Of course, the best way to judge this, is to borrow the model that makes the most sense on paper and evaluate the effect for yourself. I'm not familiar with the components you mention, so if you do evaluate the Alpha Digital (or even the less expensive Venom Digital), I'd love to know of your results.
Best regards,
Grant
