When I plugged the BG7000 into the phono socket of the BM5500 I could immediately hear that there was something wrong (two RIAA amps) but that wasn’t the case when plugging it into the BM6500, no distortions at all. On the other hand, when I plug it into the CD socket, there’s no sound at all.
However, if I really was so unlucky to get one of these special BM6500; do you think that a skilled B&O service technician is able to build the BM6500 back to its “original” state? I’ve planned to have one of my BM7000 overhauled anyway…
