last time i used altec lansing vs4121 for around 3 years, (1st model, blue LED power indicator) served me very2 well with its powerful subwoofer & tweeter, then got financial problem, sold it.. then last year i bought edifier m3300, using it until now.. so far not very satisifed with it.. miss my altec lansing vs4121 badly.. but if i'm not mistaken, now vs4121 black not same as the previous 1 laa in term of sound quality.. why ar??
