Looks like Auro is going the same way as Video 2000 from Philips.
By far the best video cassette format, but du to a better marketing from VHS, and lesser Betamax, Video 2000 went out the back door..........
What made me turn away from Auro is that with 10.1 the surround backs are sillent, and indeed the lack of content on the BD and UHD market.
Also torrent downloads is all Dolby and DTS.
They started off wrong in using 5.1 as base, and not 7.1
Even i like VOG its just a mix between front and rear hight with Auro-matic.
You could get this also with DD and DTS by using a Stereo to Mono mixer on the front and rear hight, and run this to an external amp and use "VOG".
So this is what i will be doing, i have the X6400H and on the Height1 and Height2 pre-out i have for both a Stereo to Mono mixer and run this to a Denon PMA720 that will drive my VOG speakers, and a PMA520 will drive my mono Surround Back speaker.
Here i use also the Stereo to Mono mixer so my Mono SB will work in Dolby and DTS.
Have the two PMA's behide a door, so all i see is the X6400H
