Well I just discovered my crappy Aiwa home theater receiver is defective and may have been all along. And wouldn't you know, I am three months outside the warranty. Only one of the three optical inputs is working. I had been running my DVD player through one of the optical inputs all along and it works fine, but I just hooked up my Samsung SIR-T151 HD receiver to one of the other optical inputs and nothing. I verified that it was the receiver that is defective by hooking up the optical output from my DVD to the other two optical inputs on the receiver... and nada, no sound at all. It is probably too late to make a semi-long story short, but I think I will be in the market for a new receiver and I am looking for some suggestions ??? Sound quality is about equally as important to me as features. And based on my speakers (Wharfedale Emeralds), I think I will need a true minimum of about 60W per channel. Any suggestions in the under $500 range ?
