To me, this review pretty much nails the difference between Jim's neo and ceramic line. And the audio quality is good. I can hear a definite difference between the cabinets even through my old Altec Lansing PC speakers. Despite Ken's assertion that the HT210 was the worst Bergantino ever , I think the HD210 still retains a lot of the tonal profile of that first 210 in the line. It's full and deep with some throaty mids and crisp and clean highs. The CN212, while intriguing for its weight, just doesn't have that sweetness in the high mids and highs for me. It is a little dry and airy. And it seems to lack some fullness in the low end. I think I just found my new cabinet. The HD210.
