Anyone who regularly reads hi-fi or AV magazines will know that there is a whole host of simple upgrades out there that don't involve replacing expensive components or overhauling your entire system.
Spending a little money on interconnects, speaker cables, or a solidly-built rack system can pay dividends when it comes to improving sound quality and, as long as you don't go completely bonkers with boutique cables, it can be done for a quite reasonable outlay.
Also among the improvements you can make is to look at improving the quality of the power supplied to your audio visual components. All sorts of products are available on this front, from 'audio grade' kettle leads to power conditioners that use filtering technology to actively reduce the 'noise' and radio frequency interference (RFI) commonly found in domestic electricity supplies.
Belkin's Pure AV Power Console PF240 is of the latter persuasion, and combines active AC power conditioning with protection from power spikes or surges. The idea is that you plug the Pure AV into the wall socket, and then plug your various AV components into the nine plug sockets provided on its rear panel.
In return, the Pure AV 'cleans' your power supply, reduces interference on the line, and isolates and protects each component from voltage surges. There are even coaxial sockets for your satellite dish, cable TV connection and aerial plus phone line and Ethernet network sockets, the idea being that if, in the unlikely event that lightning strikes your house, those expensive AV components should be safe and protected.
For all of this, you pay the princely sum of £217 – but at least it looks like it's worthy of such a hefty investment. It's all housed in a big, beefy box about the same size as your average home theatre receiver (153mm high), so you'll need to have quite a bit of spare space on your rack to fit it in. The front of the unit is adorned with a small LCD screen with an attractive blue backlight. This informs you exactly how many volts the electricity supply is running at, how many amps your equipment is drawing and whether or not your electricity supply is earthed correctly or not.
