you're absolutely right, but I have to try somehow and in case re-sell.
unfortunately it's hard for me to but a phonostage of the Klyne level new, I must buy pre owned units. so, I may buy something new but in a lower league (say Lehmann Black Cube: already had it, and it's way "below" the Klyne in my opinion; no contest).
then again, it's not so easy for me to have a unit loaned by a dealer before buying, so even the "new unit" option is that practicable.

but as I wrote, not all phonostages hum: "now some they do and some they don't", like Rick Davies would say ;)
so, I must live in hope :)

I think it might be more economical to reposition your system until you find a way to eliminate the hum. It is most likely caused by the magnetic field from a power supply of another component that is too near your phono stage or turntable. I had a similar problem with my Mark Levinson No.28 preamplifier, which had an external power supply specifically designed to remove the power transformer a good distance from the preamp. One time I positioned the preamp too close to a power amplifier and the phono state hummed. When I moved the power amplifier a couple of feet away the hum disappeared. Anyway, I would recommend trying to find the cause of the hum and then eliminate it because your Klyne is a great phono stage and it will cost a lot to find another just as good.

Good luck,
John Elison

  I really believe John is correct, your source of hum may likely be from the field from another system component, and a replacement phono pre may likely suffer a similar fate to some degree. If you can change some relative component and / or cable locations and notice a change in the hum severity you will be able to confirm that you are on the right track to a solution. When you play with changing component locations ... do not assume the field strength causing the problem is symmetrical, ... try different horizontal and vertical positions, ... try rotating some components 90 degrees in the same location, ... try different cable routing schemes, swap some cables to your phono pre... and try to have other components between your power amp and your phono preamp (although it won't technically act like shielding it may change the field shape around your Phono pre or its associated cables enough to improve your system response.)

  thanks, John,
  I'll try again...
  I know the Klyne is hard to beat, that's pradoxically my problem: I have to look for (pre owned) Pass Ono or something like that -not cheap anyway- to hope and find something better -or not worse.
  
  by the way, I realise I had many useful suggestions about removing the hum, but no comments yet about the Ono nor the EAR. :)
