AI-generated summary
The StarTech 20 ft Premium Toslink optical SPDIF cable for £16.43 ex-VAT is the kind of “boring but correct” purchase that tends to work out well in real offices. If you’re routing audio from a TV/PC to a DAC/AV receiver and you need a longer run, optical is ideal because it avoids ground-loop noise and doesn’t care about electrical interference nearly as much as analogue. In day-to-day use it’s also hassle-free—if it fits properly and the source supports SPDIF, you generally just get lock and silence-free playback when it’s seated right.
That said, 20 ft is long for optical. Optical cables aren’t fragile in the “paperclip will snap it” sense, but they *are* more fussy about bend radius and making sure the ends click fully into place. If you’re expecting spotty audio, intermittent dropouts, or you’re routing around tight corners, you’ll feel that length limitation more than you would with a shorter lead. For most buyers, I’d say: buy it if you actually need the distance and you’re setting up a clean, sensible cable path; don’t buy it as your default choice if you can shorten the run or if you’re in a cramped installation where the cable will be forced into tight bends.
