So I subscribed for a year of the digital subscription of Audio on Magzter for about 8€ O_o…had a bit of a discount I must admit.
Btw the paper magazine costs about 4 € so I think this was a good call, mostly because I tend to trash paper magazines after a few years.
The What’s Hi-Fi subscription is almost the same price but I got a friend that shares his magazine with me, so no need to buy it.

Updates
I didn’t renew the Magzter subscription, I enjoy reading on paper too much. 
11 Oct 2018 I would later drop the paper subscription because it focused too much on the high-end gear.
