Cattledog, please elaborate on those differences. What do the acronyms stand for? What are the features and what do they offer? Which receiver has them, the SC-05 or the TXH?
Not to put words into his mouth, I can tell you what he means, nonetheless.
ICE refers to the class D amplifier technology used in the SC line. Class D has the advantage of being more efficient. This tends to yield more power, and less weight. Read the SC-07 (I think it is) review over at Audioholics. Gene seems a bit down down Pioneer's bench tests, but that seems to be a complex issue, because benchtests seem to bring out the worst in class D based amps, and are not necessarily representative of real world audio. You be the judge.
PLQS is supposed to reduce jitter. There's not a lot of concrete data on whether it does, but the potential is there. If you don't know what jitter is, you are almost better off not knowing. It's so often debated, yet little concrete proof exists for whether it's a problem, especially over HDMI. Also, jitter increases with HDMI cable length near as I can tell. Short cables may have no issues. My feeling is to not worry about it, but that's just me.
Wolfsen is a brand of DAC. People debate the merits of DACs all the time, but can never offer any concrete listening tests to back it up. Really, DACs all have amazing Signal to Noise ratios, flat response curves, etc. Maybe there are subtle differences, I would not know.
Note that your signal goes through many electronic components. From the DAC you have the primary op amps after the DACs, various gain stages, more op amps for buffering the audio, volume control chips, and of course the amp circuits themselves - blah blah blah. For maximum flexibility, you want a 192khz / 24 bit DAC, but it seems only the cheapest receivers lack those these days!
