Here's my question: I had a question about the Elite 45TX receiver. I have Polk LSi speakers that are rated at 4 ohms, but which actually average around 6 ohms according to Polk. Will the 45TX have a problem driving these speakers? I don't see any mention of ohms in the specs. Also, does the 45TX come with 7.1 preouts to hook up an external amplifier? Here's the reply: Thank you for contacting Pioneer Electronics, Inc. The recommended rating for Pioneer receivers is 8 ohms or more, but 6 ohms should be OK. Thank you Hmmmmmm didn't really answer the speaker question and didn't even address the preouts question. Sigh. I have a feeling that the people responding to inquiries at big companies like Pioneer are just people off the street with spec sheets in front of them.
