If I ever upgrade, it will be a Class D streaming amp and I know I won't buy anything with stuff I don't need, such as Dirac correction, phono stage, CD player etc. I'm happy with the kit I have for the time being, but it's nice to know what's on the horizon, if your finances ever change. Some incredible kit out these days and it's a great time to be into HIFI, if funds allow of course. I would need to buy something with an appreciable increase in sound quality and feature count. I hope the internal SSD feature takes off. Not seen M.2 in any other devices. I'm sure these SSDs will find their way into TVs and Sky boxes at some point, for recording stuff. I'm not sure what's out now, or soon to be released, which could be considered a game changer. The market's not been stirred up for a while and it would be great to see something incredibly different, with a unique selling point.
