Not liking my new purchase - surprise This hiss is there, still noticeable on quiet classical for example. On Bluetooth mode it's a joke. Someone else has had this issue it seems: They also have a feature of powering off when there's no source which I'm okay with and for which I've read online that Kef can provide updated firmware if you email them. Except it's been a week and no response. And it turns out when they receive a source, say I press play in Spotify, they still just sit there, on standby, requiring me to power them on. Bit annoying. They do sound great though from anywhere you are in the room, the speaker design is spot on in that regard. Eyeing up the Ruark MR1 MK2 now Slightly confused as to the output I'd use on my mobo though: https://www.gigabyte.com/Motherboard/GA-Z77-D3H-rev-10#sp I have 3 options (I think): S/PDIF Out 3.5mm Bluetooth (would need to buy an Aptx dongle though) So is my S/PDIF out the input for the speakers Optical input (Toslink)? Is this better / worse than 3.5 > 3.5mm?
