What? How doesn't it have any gapless playback format? Then what about "FLAC" and others like "WMA, OGG, AAC" etc. formats that are indicated on it's specifications on mp4nation.net? Most of my archive consists of .flac files and it's indispensable for me. 
@rawrster
I met with a comment/review which says that "...with clip+, sound is produced closer to S9 ( which has the same SQ with D2+ IMO) which is on the dark/warmer side of the sound. Clip was more analytical and better". If it is so, I can eliminate it as well as iPod Video - I also don't want it anymore.
The other things like touchscreen, buttons etc are disregarded, but the battery life. I know Cowon is the best, though I can sacrifice some for the SQ wise. And if I didn't get you wrong, and also regarding the comment above, I eliminate the Clip and Clip+ as well. They are so cute and easy to carry, but I want a real upgrade that worth my another hundred dollar (or a little more) seperate from my S9. 
@Dev Avidon and Surreal.
I don't care about touchscreen sensitivity and UI as much as the SQ, but the battery life. It really concerns me. For instance, approximately how long does it play flac files with lowest screen-lighting and moderate sound levels such as %50 - 60 ? And is it really a heavy and a big one to carry in pocket? IMHO, I don't mind carrying my S9 with me even it is summer or winter.
So it seems that it's better to eliminate this restriction as well.
By the way, I had already read many threads and comments, but it's really hard to search within hundreds of page, plus I'm totally confused, so starting a new thread an easy way to have a direct idea - so all of your efforts are appreciated, thank you all.
One last inquiry; could anyone tell where exactly Sony A series (eg A845) can set among these rivals, in means of SQ of course?
