Hi Guys need some help........ I currently have a Celestion AVP305 speaker package. For those of you who need a reminder\introduction review is http://www.homecinemachoice.com/cgi-bin/displayreview.php?reviewid=3421 Basically these are made in the same factory as the kef eggs. The subwoofer is in-fact a re-branded PSW2000 (kef eggs mk1 sub). Now my question. Would it be worth upgrading to the kef 2005.2 speakers in terms of musical quality ?????. To me it seems that there would obviously be an upgrade but would it be substantial ? Is it worth the extra cost ?
