can pm me the price for PL50/PL30?
currently have PL20. Are PL50 and PL30 worth?

thanks for the PL30.
I bought one PL20 before actually.
The mid and treble are almost the same.
juz the bass are better than PL20, and it is worth.
now i'm using a less bass PL20 in office, and use PL30 at home ^^

and one thing, anyone feels that the bass settings got differences?
i din notice any bass differences there.
the deep bass setting is turn the wheels towards the wire, right?
