off topic a bit.... r&b is my soul food, i'm a big fan of this genre also neo soul. however i normally listen to male solo, duo or group mostly from america only (with certain exception of female) and currently i'm more into neo soul (i think i have huge collection from ealy 1990s till now - u name it i might have it either mainstream artist, known label, underground to independant label- i also have dozen of rare collection where i normally trade over ebays).
back to your qs, i have ice setup in my car with the budget you have (very simple and basic but havent tune in properly, i tune according to what i know and i like to hear coz no time to see zenn, his tt so far from my house, maybe if i go there ask him to belanja my whole family...hehehe - but so far oklah the sound to my ears),
btw my suggestion ...all you need to do is do is
1) state your budget (which u did)
2) decide what item you want? front comp, HU, amp, sub?
3) compare product after reading review
4) makes decision (either buy new or used)
5) survey everyday in zth marketplace ice section, makes notes if you saw something u want and start nego. dont commit first ok sometimes its good to wait for few days or weeks or month sometimes better product sells cheaper but of course buy from trusted seller lah (i got mine from here and so does the item in my previous car)
p/s : correct me if i'm wrong but r&b can be SQ and SPL so its very hard to tune coz they use many instrument and sampling. try playing r&b cd from 1990s till 2000s u'll hear different sound - maybe the way the mastered it.
neo soul is even worst, hehe dont believe me try playing d'angelo debut album and his 2nd. or rahsaan patterson or lynden david hall or raphael saadiq or van hunt or dwayne wiggins and the list goes on.
anyway mine is all original cds not burn cds or mp3.
