Thanks Darrell for posting ^
this info here, and like you it is also my understanding, from the readings:
1. Arcam AVR850 : "Full" Dirac Live version, and for twelve channels (7.1.4) of Dolby Atmos and DTS:X immersive audio.
2. Arcam AVR550 : "Lite" Dirac Live version, and for eight channels (5.1.2) of Dolby Atmos and DTS:X immersive audio.
This: Unofficial @ this time.
My personal opinion: This is all very good; Dirac Live with Emotiva, with Audio Control, with Arcam, and with other hi-end companies.
It's a start in the right direction, and with time it's going to improve (Dirac Live's implementation and operation), plus it's going to spread over into more receiver's and pre/pro's manufacturers, and becoming available in them less expensive receivers and pre/pros too.
Then, from eight (5.1.2) to twelve (7.1.4) channels of room EQ, and then fourteen (9.1.4), and finally sixteen (9.1.6)...for two rows of seats. ...Plus all the variables between depending of our own room's dimension and accommodation.
Dirac Live is for us what Trinnov and Datasat and JBL Synthesis and Steinway Lyngdorf and Auromax and Barco are to others.
Audyssey, ARC, YPAO, MCACC and AccuEQ and Sony's own room EQ system are superseded by superior EQ systems in the year 2015 and beyond...IMHO.
...Or unless they implement the improvements missing in their automatic EQ systems. ...With more DSP processing power from bigger or more chips.
And if not, a way to advance in combination with our laptops (more processing power in those).
...Just my opinion on the current state of affairs...Room EQ systems in our pre/pros and AV receivers today and tomorrow...with 3D sound immersion and UHD Blu-ray. ...OLED 4K 3D UHD TVs (both curved and flat, and super thin), and 4K/HDR front projectors with 48fps support.
The future looks so bright that I have to wear shades.
...No wonder I resemble my avatar.
