This is odd.
The description for the DTT2500, which is the system pictured in the first post, says it supports PS2, but under "More Information" it only says it has a coaxial input. Of course, since they say in the description that it supports PS2 they may assume you know it has an optical and so they just don\'t put it in the "More Information" section.
The DTT3500 system (notice, 3500, not 2500) does have an optical input specifically mentioned in the description. So that one certainly does support the PS2.
Bah, just save up $200 more and get the Kenwood HTB-503 at Circuit City (or online from somewhere), it\'s a really good "Home Theater in a Box" system with every connection you\'ll ever need on the receiver and it certainly will sound better then those little multimedia speakers. Not to say the speakers in the Kenwood are the greatest, the center is far from the best thing on the planet, but the worst of those speakers will be better than all of the speakers in the cambridge system. In fact, the subwoofer in the Kenwood system is a bargain at the price for the whole system.
