No, I haven't posted my review of X19HD yet, just some impression. Between C30, Clip+ and X19HD, C30 is still my default on-the-go choice. Comapring X19HD to Clip+, I 'll say Clip+ is slightly more detail and has better sparkle, but also more forward on the vocal. X19HD sounds more neutral overall and has better bass texture (without the bass boost). X19HD's bass boost is much more useful than the EQ on Clip+ stock firmware, but not quite as versatile than the RockBox's EQ. As much as the stock firmware on Clip+ isn't considered to be great, it is still easier to use (and overall more sensible) than the firmware on X19HD.
