Martin, thank you for reply! Well will listen to my Beovox M-100 with a native "stone" BM 4400 or Scan-Dyna 4000 (another great receiver).

Martin, were there more powerful B&O valve amps which can match to M-100 speakers?

Martin thank you for the info! What is the power output of Dirigent? Alexey

Does anybody know technical characteristics of this unit?

I didn't measure ESR. But probably I will do it if I get the special device. It's interesting for me too.

Recently I have decided to replace the caps in the crossovers in my Beovox M-100. After some difficulties I have found the original ones from Wicon. (I think the crossovers in your speakers have Wicon capacitors too). My speakers are 30 years old. When me and my friend began the recapping we have measured the most critical old capacitor from the plate

Jacoll96: When I turn the Beocord off I get a popping sound through the speakers. John You could switch off the left button (1 or 2) on your receiver before you turn it on or off. And there will be no any popping sound

Simon, I'm sorry for my late answer. Thank you! I know Martin, he is a great B&O specialist. I've found the way to get the caps that I need. If it isn't occur, I will connect with Martin. Alexey

Hi! My music system consists of Beovox M100, Beomaster 4400, Philips CD880 and Lenco L75. I like the sound very much. But sometimes I feel a light lack of clearness and transparency. I think that the capacitors of the amplifier need to be replaced. The small electrolitic capacitors in the beomaster are ROE and Marcon (?) and two power bipolar caps are
