OK, I'll try to add my tuppence worth, trying to be objective.
I just got a Project RPM5.2, and had an X-Ray v3 for a long time, so probably know the character of your proposed setup fairly well.
I think that without doubt vinyl replay does sound good, but from a technical point of view it's an enormously difficult thing to do, just because of the physics involved, and therefore good replay costs money. I think, therfore, that with a Genie you *will* wonder a bit what all the fuss was about, not because of an intrinsic inferiority of vinyl but because in your system it's not going to make you want to throw your CD collection away. The problems with vinyl (surface noise, getting the setup right, tracking distortion towards the end, inter alia) will be apparent in the Genie (these are the things that get better the more money you throw at it) and you won't be 'blown away' in the way that I was by the X-Ray.
The biggest advantage you will have is that with minimal investment you'll be able to listen to music that you wouldn't otherwise be able to listen to (in my case, 500+ LPs that I don't have on CD), and that alone is worth the entrance price, since that's what it's all supposed to be about after all. Add to that the 'event' or 'experience' of listening to a record (which can't be understimated) and strewing dozens of them round the living room as you find more and more stuff you haven't heard in years, and you can't go wrong. Just don't expect to throw away your CDs just yet.
Oh, and my previous post about a record cleaner is a given - without it I think you'll just take the genie back to the shop.
Am I rambling?
