Currently Pandora is not part of the HR34, but I'm guessing it is in the works to go along with the HD interface that is coming soon, to match the HR2x receivers.obeythelaw2004 said:
IMO, the HR34 is the way to go, with maybe another HR2X receiver or two if you want additional rooms.
One of the drawbacks of the HR34 is it's new and it's a bit buggy, so it's gonna take a little while to iron things out. However, IMO, the benefits of the 5 tuners and the PiP(if you are a sports fan, this is REALLY nice) outweigh the current issues.
One thing to keep in mind, when you are a "new" customer, they will give you some great deals, especially on things like the HR34 to get you in the door. If you decide to skip the HR34 now, and then decide you do want it later, as an existing customer, it will be a tougher to get a good deal on the upgrade.
