I've spent the last few weeks (and several hundred pounds) replacing/upgrading all the cables and related bits in my system. Previously it looked like this: Sky box - media receiver: Cambridge Audio scart (2m) DVD - amp: Cambridge Audio phono (1.5m) Front speakers - amp: Cable Talk 3.1 bi-wire (5m) Centre speaker - amp: Gale Hyperlatz (3m) Standard power leads for all equipment Rubbish, cheap metal banana plugs on some bits Additionally, all of the cables - mains, audio, video were all bundled up behind the unit. Basically one big spaghetti soup of wires. Now however, it looks like this: Sky box - media receiver: IXOS XHT611 scart (1.5m) DVD - amp: Puresonic phono (.75m - home made) Front speakers - amp: QED Silver Anniversary bi-wire (3m) Centre speaker - amp: QED Silver Anniversary bi-wire (.5m) All power leads have been replaced with short (.75m), double shielded, earthed, double ferrite, home made leads Quality gold plated banana plugs on all terminals - amp and speakers I have also routed all of the power cables away from all speaker, audio and video cables. The power cables actually go through the wall into the adjoining room and don't go anywhere near any other part of the system. So, what has this change made to the overall picture and sound quality? Well first let me say that as my original set-up was pretty basic I was expecting a definite improvement in all areas. After all, everything you read/hear/are told by "informed" people says this is the case, so it must be true, right? As I replaced all of the bits over a period of a few weeks, it was difficult to see any drastic changes/improvements, possibly due to the incremental effect of replacing a few bits at a time? So I did some direct comparison test by plugging the cheap phono into the DVD L channel and the Puresonic phono into the DVD R channel. By doing this I was able to make a direct comparison in real time between both cables. I also swapped the scarts on the sky box (as quickly as possible) to get a near real time comparison. For the speakers I kept one wired up with the QED and as I had sold my Cable Talk, I used a spare length of the Gale. The power leads were a bit more difficult as everything had to be shut down and then powered up again but it was still possible to compare within a minute or so. And the overall result? Zip, zilch, nada, nothing, zero. Yep, that's right. There is absolutely no difference in the picture or sound quality before and after the changes. I would like to think there is and I keep trying to convince myself but I have nothing to lose by stating the truth - after all I have already spent the money. To be honest, I wasn't really expecting any improvement/difference as I have stated many times in the past that if your existing cables are not degrading the signals in any way, there is nothing to improve upon. So, was it worth doing? Well strangely, yes it was. If nothing else, I proved to myself once and for all that you don't need to spend huge amounts on cabling and interconnects to get the same results. Also, I was able to significantly reduce the sheer amount of cabling by making bespoke lengths much shorter than the standard items. Finally, it just looks nicer with all these expensive looking cables. So much so that I am thinking of removing the plasterboard from the study wall and replacing it with a sheet of perspex. Before I get flamed and people start spouting physics and lab test results, I'd just like to say that this is not theory or educated guesswork but fact. The results can't be disputed. Neither I nor anyone else who has seen the before and after can notice any difference.
