that s true, the future models will probably have more features.There are always the USB ports on the 105 models. They accept Stereo & Multichannel music files - DSD & FLAC.
On future Oppo models, I would expect to see support for Stereo & Multichannel up to DSD 256fs. That's what Oppo has been adding in their newer products like the HA-1 and HA-2 headphone amp/DACs.
But Oppo says no new disc players until 4K Blu-Ray. That could be awhile.
Still I think an affordable multichannel dac would be a good business move for Oppo, tp compete with the exasound high price models. Plus file playback will be more and more the norm from what I see and read.
But you know that better than me as ypu are at the forefront of computer audio, together with Ted B.
