I can't comment on the vd cable having not heard it ...... What I can say is that in a system composed of reasonable components [mine] you can hear the effect power cables make .....as a standard I use lapp classic three core cable this works out about £6/m without termination ....in a resent listening test four power cables were swapped a kettle lead , my lapp, a missing link cable and a silver cable. Cost ranged from 50p to £150.... The cable was swapped on my valve pre amp clear bottom came the kettle lead made everything dull and muddy next came the lapp big step forward over the kettle lead and was just pipped by the ml which was a disappointment for its owner..and finally maginally better was the silver [3x 1.5mm solid core in ptfe] just more natural.
So the moral is you don't need to pay mega bucks just get a good cy cable and decent termination ...if you can wire a plug why pay hundreds of dollars?..the down side is you normally need to buy a 50m reel of cable. Theres a very good explaination as to why the last few m make a difference ......quote ..... Good answers to power cable issues How can an aftermarket power cord, which represents the last 6 feet or so of many miles of cheap in-wall and underground wiring, make any difference at all to sound or video? There are many misconceptions about the basics of power transmission and power quality that make it difficult for people to understand why any aftermarket power cord can impact the performance of a home A/V or professional recording and film system. The fact of the matter is that Shunyata Research power cords have made dramatic differences in all manner of consumer and professional recording, sound and film systems. Many skeptics question even the possibility of an aftermarket power cord making a difference in electronics performance. Shunyata Research is pleased to provide answers. The first and most obvious question is -- can power cords make any difference at all? There is no sense in talking about theories of operation if we cant agree that there can be an obvious visual and audible effect when applying a competently designed aftermarket power cord to electronics. Most of the thousands of professionals and consumers that use Shunyata Research power cords started out as skeptics and have answered that question for themselves through their own experience. The only cases where a high quality power cord may not have a significant effect is when it is coupled with a poor quality power conditioner that creates a high impedance to instantaneous current flow problem. The most common misconceptrions about power transmission and their simple technical truths follow: Misconception #1: AC power is like water coming from a large power tank, flowing through several 10s of feet of power hose into a component. This implies that the component is at the end of this system. Answer: Actually, the component sits between two power conductors: the hot and the neutral. AC power oscillates(alternates) back and forth at a 50-60hz rate. So power does not pour into the component at all. The components power supply is within a complex network of wires and connectors. Due to their obvious proximity, ALL of the wire and connectors can and do affect the performance of the components power supply. Misconception #2: AC power can be contaminated just like water in a hose. This implies that once the water iscontaminated at some point up stream, that is must be cleansed before it arrives at the audio component. Answer: As stated in #1, the component is not a the end of the power hose. It is between two power hoses and the current is oscillating back and forth. Further, current is not like water at all. Electrons cannot be contaminated. There are two aspects to power transmission: the EM wave and the current flow. The current itself cannot be contaminated but the EM wave can be modulated with other frequencies. We usually call these other frequencies noise or EMI. Within thevarious parts of a power circuit there may be EMI in certain parts that are not present in others. EM energy can be transformed or redirected to lessen their effects. Some power cords for example, use capacitors, inductors, or ferrites in an attempt to control the EM fields around the audio component. The success of such an approach is completely dependent upon the specific power supply design and its reaction to the added reactive capacitance of the power cord. cont..... -- zanash Acoustician and builder of interesting cables ------------------------------------------------------------------------ zanash's Profile: http://forums.slimdevices.com/member.php?userid=12157 View this thread: http://forums.slimdevices.com/showthread.php?t=45323
