D800 upgrade, is it worth it? Alternatives?

[Philb]

My current thinking is to immediately do nothing other than to spend money on music - I recently started to use my turntable again and it sounds great via the Devialet phono stage, much more engaging to me than playing a file from a computer (which does not seem logical given what happens to the analogue input) - so I am going to try to control myself and be happy with the gear that I have (I know that it is a great struggle though!).
