Someone here or on another audio forum recently reported taming the treble output of B&W CDM1s by upgrading capacitor(s) in the crossover network. I didn't take a note of this because I got rid of mine after 6 years of struggle trying to integrate them into a suitable system. If they hadn't been so good in all other respects I wouldn't have bothered, but a combination of warm amp (Plinius 8150) and cdp (Arcam CD93) still didn't work. It wasn't that the treble was harsh or otherwise objectionable - there was just too much of it. I've ended up happily with New Zealand-made Image speakers with Morel drivers, including a soft-dome tweeter, but these are not yet readily available outside NZ.
In the same room with the same ancillaries they give an all-round better performance than either the CDM1s or the newer 704 or 705 models (which I've trialled) at less than half the price. But if I had been able to tame the treble on the CDM1s it is quite likely I would have held on to them for life. I've got no issues with the rest of their pwerformance.
