I currently have a Marantz SR7300 paired with B&W 600 series speakers (see sig.). While I like the sound, for some reason, I feel like I'm missing something. I don't listen to 2ch music very often (if at all). Usually, directv, dvd, or surround audio. I've heard some good things about the Pio Elite 47tx and I also think I might benefit somewhat from it's additional power (extra 30w over Marantz). Let me know what you guys think. Thanks.
