speaker systems

First of all, I would like to say that Sony T55 speaker is really an amazing product, I have friends heard the sound and immedialty asked me where to buy,and later, she got 2 sets,one for herself and the other as a gift to her boss@_@. Since I am so pleased with the now-discontinued-model T55 speak I brought last year, I went to Sony show room yesterday and wanted to get a new one. But the salesman told me that the model was discontinued, and he suggest me to get the new T57. Althougt I don't like the new color pattern of T57, I finally brought a blue one back home(after all, what matters most is the sound of speakers,not the looks of them,right?).... However, after 24 hours break-in, I found that the new T57 is not as good as my old T55, in terms of the sound quality: it lacks of the lovely mid-bass which T55 generate and is overall not as balance as the old model...I am disappointed to Sony this time...

So I strongly recommand anyone who are looking for a great sound quality, small and portable speaker to consider T55 before they are out of stock. Well, T57 is not that bad, but you will miss T55 if you had heard the sound of both model...
