i have my nokia N8 playing with either TTPod or FolderPlay. FolderPlays is simple play by file/folder/directory with no effects nor eq whatsoever but it does FLAC/APE/WAV + the rest of the normal lossy stuff.
TTPod on the other hand only does WAV as lossless & normal MP3/AAC/MP4 but has amazing skins with great spec effects including a buncha room/hall enhancements besides sound fade, stereo widening, bass boost & loudness. best of all it has a very good 8band eq with a number of adjustable presets & 2 fully custom eqs. it also has the ability to download songs, covers. music charts and realtime lyrics. its crazy good & better than anything i could install on my now ex touch 3g so long as one doesnt need FLAC.
all in all, its as good as a sony s6x6 dap 'cept much better looking - heck TTPod even has sony skins. before i got the N8, my sansa fuze went south on me & i was looking to replace it with an equivalent clip+ but the N8 saved me some money esp with its built-in 16gb. just got myself a 32gb microSD lastweek so i do believe im golden.
+1 for the Nokia.
