So whats the verdict?
From peoples (early impressions) I gather in terms of sound quality (not counting, build or UI).
ipod/cowon/sansa clip etc
*Tera player omitted.
The above list is not an accurate list, but is gathered from various DX50 and X3 posts.
*Please order the Daps in order of preference.
*Only include Daps you have actually listened to.
*include any extra information you feel is relevant.
You may already got everything in order.
Shamefully, I only auditioned ipod (aka diyimod) and a Cowon J3. To these ears my diyimod with my favorite caps and lod sounds way better than the J3, the two not in the same league. That's really off topic here.
Musicheaven initially reported his diyimod sounded better than the DX50, but I am not sure if he has reversed his opinion by now. Icefalkon reported his DX50 sounded better than his RWA iMod.
Keep in mind all these mods were not done exactly the same so it's hard to say all the mods are equal ( and I doubt about that).
I am interested in the DX50 only for two reasons 1) being curious 2) potential for diy mod at this price tag.
