First 'upgrade' for a v.long time...

Hi,

 
For the first time in a decade (round numbers) I'm looking to purchase some hi fi equipment, and the landscape has changed, rather. For the last 10 years or so I've been living with a Linn Classik and a set of Ruark Prologue One floor standing speakers. Before circumstances dictated I moved to a one-box solution I'd been pretty happy with a Cambridge CD3 / Musical Fidelity B200 combination driving some Mission speakers. The only item I have kept from that separates system is a (somewhat vintage) Michell Focus turntable which has been stored unused since then.

I now have the chance to buy some kit and I wouldn't mind some input on the following options.

1. Cyrus 6vs2 amplifier and CD 6s CD player, possible keeping my existing Ruarks or changing them for..?

2. The Roksan Kandy amp and CD.

3. Picking up a second hand LK 100 or similar and using it to upgrade my existing system.

4. Other suggestions?

 
My overall budget is around £2k although I don't feel the need to spend up to that if it's not necessary. In all cases I'll need that budget to include a wall-mounted turntable shelf, speaker cable and so on. I'd need an outboard phono stage for at least some of my options and, if I were to use the Michell turntable, probably a damn good service and a modest cartridge.

I really enjoyed the sound of my old Musical Fidelity amplifier, but their products seem to be pretty pricey these days and out of my reach, sadly. I intend to go and listen to at least the Cyrus and Roksan options...but is there anything else I should consider?
 

Lastly, what sort of improvement on my existing CD audio reproduction could I expect if I were to spend £2k wisely?

Thanks!
