I have a really old HTIB receiver, the Onkyo HT-R520. I think the speakers are damaged but the receiver seems to work just fine. I was thinking of using the coaxial out on the motherboard to the receiver. Will a basic RCA cable do this job?
My main question is, If I buy some cheap bookshelf speakers like these:
And use them as a 2.1 with the huge sub woofer that came with the HTIB will the sound quality be better than the Logitech Z323 speakers that are currently being used?
