Tomorrow should be an interesting day as the long awaited (and about a year delayed) release of the DTS:X Firmware upgrade for select 2015 Onkyo model A/V Receivers is scheduled to happen. Happily, I have one of the receivers that will be eligible for the upgrade, the THX Certified TX-NR747 which you can now buy for a great price ($478.00 new or $438 is you are ok with certified refurbished).
There are other models available for upgrade as well:
If you are looking to upgrade to DTS:X and don’t want to spend a lot of money, the TX-NR646 at under $400 is probably the best bargain out there as long as it meets your other needs. The DTS:X Firmware upgrade should be available tomorrow at the Onkyo Website. I plan to try it out with The Huntsman: Winter’s War which is available on Blu-ray with a DTS:X track.
How does DTS:X differ from Dolby Atmos?
Both DTS:X and Dolby Atmos are object based but DTS claims that DTS:X works no matter how you have your room laid out, offering an excellent presentation with maximum flexibility. That sounds great, if it is actually that flexible. For me, that remains to be seen. The other difference is DTS Neural:X versus Dolby Surround witch are the competing versions of a non native object based upmixer for height channels. Similar to the comparison between Dolby Pro-logic II and DTS Neo:6. How will they differ when employed on non DTS:X or Atmos tracks remains to be seen.
