Sure it’s 7.1.2? The picture of the back panel was hard to make out, but it looked like it had two discrete sub outputs.

Yes, it does have two subwoofer outputs, but they are both identical and cannot be configured separately. I still call that 7.1.2

Pretty glaring error for a Sound and Vision Review; this unit does not use class D amplification. The amplification type is listed as "Direct Energy" on Pioneer's spec sheet and website, which is their terminology for their class A/B topology. Class-D driven models have always historically been prefixed with "SC" rather than "VSX."

This is the description of the Direct Energy Amp from Pioneer. "Direct Energy Amp These stereo components are equipped with high performance Class D technology inherited from our flagship AV receivers and amplifiers." Thanks for your interest!

That quote is taken from a stereo system spec sold in Europe and does not apply to AV receivers. In AV receivers, only "Direct Energy HD" are class D.

According to Pioneer, the VSX-LX504 uses class-D amplification.

I find it interesting to give anything a minus or plus from specs as it could have measured 150WPC but rated conservatively. Since we don't test things around here anymore lets compare to receivers that "measure" 150WPC would only be 1db more than 120WPC. These are insignificant changes but considered big in measurements.

I wrote a lengthy commentary about the review and then hit the "Preview" button. It previewed OK, but there was no way to then submit the comments. This time, with this short follow-up note I will hit "Save" and hope for the best. This will be my last comment of any kind to your internet site. It is too hard to deal with.

I got a look inside of the lx-504 and the lx-704, the lx-504 is not a Class D amplifier, it's has a similar high current class A/B amplifier system to that of the onkyo tx-rz830, the lx-704 on the other hand is a full on pioneer made class D amp unit.
