Unless Adcom has made a running spec change, the GTP-870 HD has HDMI v1.0. I used to be a fan of Adcom, but after careful research and several telehone calls to Adcom, I would not choose this unit (especially at $2500.00). Read the manual carefully and you will find several quirks in the basic setup and operation. Outlaw has done a much better job. I agree that Outlaw needs to move faster on a replacement for the 990. In the meantime, you might consider the new Integra DTC 9.8, MSRP $1600.00 over the Adcom. Just my opinion.
