A new product from Denon is getting the tech world's knickers in a twist with its rather hefty price tag.

The high-end audio company is marketing the AK-DL1 "ultra premium Denon Link cable" Ethernet cable at $499.

Measuring 1.5 metres, it's an item that you can pick up in the UK for less than a quid.

"Designed for the audio enthusiast" Denon states the wire is made from "high purity copper" and offers "high performance connection parts".

The promise is that the pricey accessory will "bring out all the nuances in digital audio reproduction from any of our Denon DVD players with the Denon Link feature".
