How is the problematic setup grounded? Have you tried the Colibri on the other arms and gotten no hum? Cheers,

Colibri or Hummingbird?
Hi all,
I'm experiencing a rather annoying 'hum' with my Colibri XPW cartridge. It sits in a Reed 3P tonearm on a Micro RX-1500 and goes into a Boulder 1008 Phono amp (the Reed tonearm cable has RCA plugs, so I'm obliged to use the Boulder's RCA-XLR adapters). The hum is typical to the Colibri/Reed combo. The two other tonearms I use on the RX-1500 (one of which also goes straight into the Boulder) are completely silent, no matter what cartridges are used.
The hum resides in the background while the arm is in stationery position, but it turns into a fierce 'humming' the moment I touch it, again retreating to the background when I release the arm. Strange enough this problem comes and goes and had almost completely disappeared for a while. But for some reason it has returned again, without having made any changes in the system.
It's a complete mystery to me, so I hope some of you might be able offer some explanation. And if possible a way to get rid of it.....
