Based on my experience, I'd say that assumption is not accurate. I own the CD5i-2 (the "italic"), and owned the original CD5i before. The new CD5i-2 is a significant improvement over the original -- less of an electronic edge to the sound, warmer, fuller, more natural sounding, lively but not edgy. The difference surprised me -- I had both players on hand for a few weeks and was able to make direct comparisons. Maybe it has to do with the new DAC (Wolfson) in the later model? In any case, while Naim has only distinguished the new model from the old model by italicizing a letter, they have in practice produced (in my opinion) a significantly more musical and engaging CD player.
