It's the August bank holiday this weekend and that means – for many of us, at least – an extra day to spend at our leisure. And it's an ideal chance to start building that new hi-fi or home cinema system, or upgrade an existing set-up with some fresh new kit.

But we can appreciate that finding the right deal(s) might not be so straightforward, with plenty of retailers that are looking to capture your attention with a smorgasbord of discounts and packages designed to tempt you to part with your money.

That is why we've donned our deerstalker, dug out the magnifying glass and channelled the spirit of Sherlock Holmes to go in search of the best bank holiday bargains out there – from five-star 4K TVs, to Award-winning hi-fi separates and more...
