Hi! I apologize for the mistakes, my English is not very strong. I just bought a CT-X3000 now. Compared to a WK-3300, unfortunately, its sound is not nearly as good, it looks very plastic, box-like. The sound of the WK-3300 is much clearer and livelier. Additionally, the CT-X3000 loudspeaker has a constant noise (hiss), regardless of the volume. Is it like others? Or did I get a wrong copy? Thanks in advance!
