It's important to be wary of comparing equipment purely on the basis of features - it can be easy to overlook other, important characteristics such as sonic performance (how good it actually sounds) and quality (how well built, how long it is likely to last). It is particularly dangerous to base the comparison solely on one desired feature. As far as features are concerned, however, the XR70 and 1070 are very different beasts. The two are not really intended to provide the same things - the 1070 offers much more extensive capabilities. The 1070 includes DVI switching (2 inputs, 1 output), whereas the XR70 includes a single HDMI input. The 1070 includes 4 optical and 4 coaxial digital inputs, compared to 2 of each for the XR70. The 1070 offers 3 component inputs (2 for the XR70), 3 audio inputs (2 for the XR70), a 7.1 analog input (5.1 for the XR70), bass management for the multichannel analog input (which the XR70 lacks), 3 rear audio/video inputs plus a front input (2 plus a front for the XR70), seven channels of amplification (six for the XR70), a more extensive array of processing modes (inlcuding DTS 96/24, Pro Logic IIx, and Dolby Headphone), and based on previous Outlaw gear we can expect much more robust bass management (most likely the 950's triple crossover, which is much better than the XR70's fixed 100Hz crossover). Also, the 1070 offers pre-amp outputs, something that the XR70 lacks entirely. If you do choose to use the 1070's internal amps, you'd have a much better means of connecting them to your speakers - nice heavy metal binding posts for all seven channels, a far cry from the plastic binding posts for front channels and spring clips for center and surrounds on the XR70.
