In my house I´ve got three link speakers (BL 2000 in the kitchen and in the laundry room in basement and a BL 3500 next to the fire place in the basement). If I touch the aluminium parts I can fell a weak vibration, almost like they would be electrified with a low voltage (and no current). The parts are the tube with buttons (BL 2000), the cooling parts on the back of the BL 2000 and the tube of the BL 3500.

The vibrations is best noticed when I barely just touch the metal and when I move my finger. Holding still or pressing hard makes the feeling much weaker.

I´ve noticed it before but didn´t care about it, but now my wife noticed it and refuse to touch them again.

As a true M. Sc. I did some tests. Disconneting both power supply and master link cable totally removes the vibrations. But when one of them is connected the feeling is back.

Anyone?

I have noticed exactly the same phenomenon in B&O showrooms though not on my system.

I have this same thing happen with most products(Non B&O aswell), not sure if some people sense it more than others.

I've noticed this too. The metal panels on 9000/9300/9500 series and the metal on BS9000 and the vertical stand. More of a vibration than anything. Can't explain it though unless it comes from the mains transformer??

"Good vibrations" perchance?

My thoughts too although Daniel claims that connecting power or Masterlink (either without the other) causes the phenomena to return - I can't see why Masterlink alone would cause this.

Agreed. ML is indeed a puzzle.

Good to hear I´m not alone!

Isn´t there a ground cable in the masterlink, meaning all covers are connected? So if one component is vibrating, the others can do it too?  I haven´t tried it with the whole system disconnected from the power net. But that must stop the vibrations even with the master link cable connected.

I think I´m getting paranoid, but I get the same feeling from the touch panel on one of my LC1 (and not from the other one)
