No offend to any BOSE owners / fans, I find BOSE sound quality is at average only, with the price tag it carries, it is overpriced, at least to me. Again, this is my personal opinion and I have no intension to challenge any BOSE owners / fans.

I own a B&W CDM1 and I love it.

The definition of "good" different from person to person, you have to listen to the device yourself, experience it and you would know whether if it is to your liking.
