B&W CDM 1 (original) need not warming amplifier

Hello. I have some comprehension difficulties as I’m half Belgium. What do you mean by …and the order of sound quality is the same. Do you mean tonality and global sound is the same but small variation in nuances of treble and bass. News: I found out that the Naim-CDM 1 only works with good quality CD’s and so I am streaming now and it sounds less harsh. Now 10% of my CD’s sounds good, the rest really bad.
