We weren't overly enamoured with the last incarnation of Merlin's Tarantula mains cable, and a three-star rating was duly dished out.

But, the company's MK6 version is a spectacular improvement. Plug it into hi-fi electronics and, compared with your standard kettle lead, the Tarantula helps your system produce a much cleaner, smoother sound.

The lack of noise allows more detail to seep through into the soundstage, with greater separation between instruments and vocals.

But the benefits aren't just hi-fi based: plug the cable into a TV, and images appear crisper, while there's greater punch to the overall picture.

It's not a spectacular difference, but we think it's a worthwhile improvement nonetheless.
