Current affairs Mains filtration removes high-frequency noise, but as Richard Black discovers Isol-8’s Powerline Axis goes the other way, removing direct current ains treatment specialist Isol-8 has been around for quite a while, but has not been over-keen to offer product for review. Evidently, the reason for this decision was due to the fact that advanced sales had outstripped supply, apparently! Now that this problem has been addressed, we’ve finally been able to get our hands on a sample and a fascinating product it is, too. In its basic form, the PowerLine is ‘just’ a mains distribution board – though it’s actually about as deluxe as such a thing can get, with silver-plated wiring, high-quality sockets, a solid metal chassis and so on. But the Axis variant adds something very unusual in mains filtering called DC blocking.

Follow the A1 Dominic Todd gets acquainted with legendary headphone manufacturer Beyerdynamic's high-performance A1 headphone amp he mission for Beyer’s A1 is all about bringing wideband audio to the headphone enthusiast. The entire circuit has been designed to transmit 96kHz signals, making it ideal for SACD, DVD-Audio or other high-resolution audio formats. Against its rivals, who often seek a mellifluous, valve-like sound, the Beyerdynamic A1 has studio-like neutrality as its design concept. In a similar vein, the A1 is styled for practicality rather than flamboyancy.

Room service Thanks to this innovative room correction device, enjoying studio quality sound in your own home is a lot easier than you think, says Richard Black Novelty is a bit of a moveable feast. A CD player can still have novelty interest if it uses a new DAC chip or a different kind of output circuit. The PARC, though, is something quite unlike any product we’ve reviewed in Hi-Fi Choice before. It’s a room correction unit, and it’s true we’ve seen the odd one or two of these, but it works in a very different way from any other we’re aware of.
