Onkyo has debuted several new tuners today at a press event, including four tuners that support both Sirius and XM, and two new tuners that combined Sirius, XM and HD Radio capabilities in one.

The Onkyo T-4555P combines Sirius, XM and HD Radio in one for only $499. Gizmodo (who also happens to have a photo of the sexy little thing) says the T-4555P is scheduled to ship "soon" which sources tell us is much earlier than "later."

Meanwhile Engadget brings to light the Onkyo TX-SR575, TX-SR705, TX-SR805, and TX-SR875 tuners that all support Sirius and XM, as well as the top-of-the-line TX-NR905 which packs the Sirius/XM/HD Radio combo. Pricing ranges between $899 and $2099.
