The reason we invest in a hifi table is to allow the music to take us as close as possible to the original event, we carefully choose the CD player we prefer most – connect it to the amplifier of our selection and finally to the speakers. We know every component is a valuable link in the chain, if one of them is not performing at the same level as the rest of the chain – there exists a problem.
By far the most overlooked link will be the power supply – the origin of all the energy for the system. The mains power supply is the beginning of the chain, then one which needs more scrutiny and attention whenever we are going to realise the utmost potential from our Hi-Fi system.
If you zoomed in to check out the incoming mains supply you would not notice that super smooth sine wave that people are taught about in science at school, you would see the result of modern life, the sine wave is distorted and polluted by countless home appliances, industrial manufacturing companies causing radio frequency interference and distortion in the main supply itself.
The national grid network has never been conceived using the audiophile or Topping DAC in mind, therefore little attention is paid to degradation and noise that could have a dramatic effect upon our home systems. This situation is about to get much worse – already most laptops and lots of other devices use switch mode power supplies ( a cheaper and smaller solution to using transformer based PSU’s) – however the trade off is electrical noise, plenty of it!
Home data networks utilizing the mains wiring as a conduit from room to room, Bluetooth phones, computer keyboards, home Wi-Fi networks all of these cause masses of RF borne interference in addition to mains borne problems.
These could be spotted by a simple test….Does your body sound better late at night or morning hours? If the reply is yes you may be being bombarded with interference from your own equipment used elsewhere inside your home – or from your friends down the road. Even Hi-Fi and Home cinema components themselves cause significant levels of electrical noise that may be passed from a single component to its neighbour, therefore the requirement to cut down as well as eliminate cross contamination is important.
The Remedy:- You have to remove mains borne interference, by fitting a properly designed filter, mains cable or perhaps a regenerator, a power block letting you effectively isolate each device through the next. we have been not speaking about slight very subtle differences here. We have been referring to very dramatic improvements in system performance, you being able to enjoy your system at anytime night or day, improved timing, tighter bass lines, higher resolution and more importantly getting more involved with the music. Manufacturers including Isol8 are experts in form of all things mains related.
Generally the price for this boost in performance is under a new CD player, amplifier or set of speakers. Generally you will find that lots of the available HDMI Cable Reviews tend not to explain the significance of the usages in differing applications of the conventional home used HDMI interface. It is extremely helpful to understand the importance of the various HDMI specifications, whereby, a Cat 1 cable is capable of doing sending an audio visual signal to achieve maximum results on a 720p or 1080i TV/LCD screen along with a Cat 2 HDMI Cable is capable of doing delivering an audio visual signal to attain ideal results on 720p, 1080i, 1080p & the newest 1600p TV/LCD devices. The conventional specifications for HiFi Audio are a number starting from 1. to 1.4 which represents the brand new HDMI specification and interface versions being eeogzu available right now, 1.4 being the most recent DHMI interface specification. However, don’t concern yourself with these numbers as any new HDMI equipped devices are backwards compatible for cabling purposes.
It is crucial that you select the minimum length of cable for connecting your equipment and obtaining an HDMI interconnect which includes top manufacture quality. To experience the best sound and video quality from your equipment the digital cabling plays a big part.
