I hade 2 Kairn in my audiophile life, uprgading from the original one ( with conventional transformer) to the SPS ( switching power suply) one and was very happy with both of them: musicaly very implicating and good transparency. But I also owne a 5103 for quite a long time and must say that, in my system, it was a much better preamp overall !!! More transparency, more dynamic and, of cours, more music ! Be aware that the kairn is phase inverting and the 5103 is not... but with a good setup, the kairn is no match for a 5103 and you can find one at a very good price now...
