King of the Castles Castle Acoustics is back! There’s a new owner in IAG and whole new range called Knight, Dominic Todd listens in to see if the old magic is still there Castle Acoustics was a Yorkshire-based company started in the early 1970s. Best known for its rich, real wood veneers and refined acoustic, the firm soon established a following from those appreciating a warm, full-bodied sound. As with many of the British greats, however, Castle fell upon hard times at the turn of the millennium and came under the ownership of IAG (International Audio Group). With IAG’s impressive portfolio that includes Quad, Castle should be in safe hands and as if to prove the parent company’s commitment, the all-new Knight range is voiced by IAG’s Director of Acoustic Design, Peter Comeau – of Heybrook HB1 and Mission 780 fame.

DAC to the future Arcam, one of the pioneers of off-board DACs re-enters the market. Ed Selley finds out if the wait was worth it Over 20 years ago Arcam produced the Back Box standalone digital-to- analogue convertor. This was one of the first (for obvious reasons, the claim to exactly who was first is hotly contested) devices that could bypass the output of an existing CD player via an S/PDIF digital output and convert it to an analogue signal via a higher-quality output stage than the CD player had internally. Consequently, the Black Box was highly regarded and sold well.

Binary beauty US valve stalwart Audio Research has launched its first Class D power amp and as Jimmy Hughes reports, its 450 watts prove addictive Given its penchant for producing large, heavy, behemoths, Audio Research’s launching of a Class D power amp is more than slightly surprising. While Pure Class A still sets a benchmark when the highest quality results take precedence, there are many practical drawbacks – excessive heat, large size, high price, massive power consumption – need one go on? The DS450, on the other hand, features an analogue-based Class D pulse-width modulated switching output stage. High output power, low-running temperature, low-power consumption and excellent sound quality are promised. But can such clever technology really challenge Class A’s sonic supremacy? Up the stakes Like most power amps, the DS450 is fairly simple.

Mobile library Malcolm Steward discovers a neat solution for losslessly storing up to 3,000 ripped CDs with zero effort, a minimal outlay and no catch The Vortexbox name represents two things: it is a suite of Linux (Fedora-based) software applications that provide users with a music library. It is also the name of the software installed on the company’s ripping NAS (Network Attached Storage) appliances. The software is freely downloadable, while the hardware – a range of fully equipped DLNA-capable (Digital Living Network Alliance) appliances – starts at the genuine value-for-money price of £385. 3,000 albums at CD-quality You can load Vortex Box software onto any PC, where once installed, it will automatically rip CDs to FLAC and MP3 files, ID3 tag those files and download the cover art.
