Linn Kairn vs 5103

Hi,

I am looking for a Linn preamp and so far I thought that Linn Kairn with slimline brilliant PS would be a best bet (short of Klimax series). I have heard good things about 5103 though. Has anyone compare the Kairn with Slimline PS and 5103? In a purely 2 ch system, would the 5103 give better performance or should I still look for Kairn?

Thanks in advance,

Rafal
