1.R501 MK2 will better in my opinion.m3500 is lower grade if compare to R501mk2.  (mk2 got tweeter,early R501 dun have tweeter,but i believe now all R501 on the market is mk2)
2.if u wan buy e3350,better buy m3300.e3350's bass unit cannot do much,it will lose control when u open too loud.
-if u wan buy C3,better buy S330.

I really wish i can try ur speaker wanna see really so geng ? becoz by defalut it oredi very good for me,very curios how the modded one perform

smokey

i think u will feel the satelites louder than bass is normal becoz what makes s330 so good is becoz the satelies performance,in another word,have good clarity,wont mask by the bass,and i think it is mainly becoz the bass of s330 is well control,not like other speaker which will spread the bass everywhere,i quite agree s330 not suitable for heavy trance song the altec lansing MX5021 more suitable to play this kind of song in my opinion,but s330 is idea for people who want the clarity, clean and tight bass   nothing to do with ur sound card la,its a good card,jus this is s330's characteristic

hmm...it depends on songs...it sound superb when playing slow rock/pop...
in trance/techno, the bass is tight but not thumping enough...
well, it depends on source too...maybe my trance/techno mp3 is low quality...

i plan to sell out some S2.1D parts
