phono amp +/- €1500

I have been thinking of investing in a separate phono stage. Right now my digital source (transport +dac) are at least as good, maybe better as my analog source.

Maybe a phono pre amp will bring my turn table to a higher level. However in my price range there are so many phono pre amps that I have no idea where to start. I do not mind to buy second hand.

Phono stages to come to my mind for what ever reasons are:
Nagra BPS
RCM Sensor Prelude IC
BMC MCCI
Astin Trew AT8000
Symphonic Line phono
Blue Amp
Goldenote Phono 2

But where to start. Would €1000 be enough to gain a significant increase in quality or would I need to spend closer to €2000.

I would prefer a phono stage that can do MM and MC.

So what do you think.
