So I have never had a computer with an optical out before. I can the logitech X530 for about the same price as the X230. 5 speakers instead of 2 makes me drool. Thing is, I've read that the X530's don't support optical, only 3 minijack connections, which doesn't work when my mpb only has a single one. Is there anything that offers a 3 minijack --> optical adapter? This would likely reduce the quality to the lowest denomenator, which would be the analog minijack instead of the optical, but this isn't a huge deal to me. Is this possible? Or do I have to go for the inferior 2.1 system? It should be mentioned that I don't really care about 5.1 sound, I don't watch many DVDs on my computer. I just want more speakers for more volume since my computer speakers are my home stereo for my downstairs. Someone mentioned to me that I might be able to hook up the 530s in '2.1 mode'? Like just ignore 2 of the minijack connections? Will all the speakers still work if I do that?
