If I remember well:

- the Beocentral website says there are only minor differences between the BM3000 and the BM3000-2 and that both have the same power;

- but the book of the Jarman brothers says that the BM3000 was 2x30W and that the BM3000-2 was a more powerful version with 2x40W.

Can anyone please confirm?

Many thanks, js

Yep, the original 3000 was 30 W per channel and the 3000-2 is 40 W per channel

The 4000 was 60 W per channel and the 4400 was 75(though a entirely different design)
