Audyssey Dynamic Volume -versus- THX Loudness Plus

Thread Starter 
With the official announcement of the Onkyo TX-SR806 this morning, I began to wonder:

Does anyone have an idea how Audyssey Dynamic Volume (ADN) compares to THX Loudness Plus (TLP)? I've had my sights set on a higher-end Denon AVR (just as soon as Denon makes good on their firmware promise for ADN to be added - same feature even their new low end AVR's have now) but if TLP is comparable then I may just go Onkyo 806 for this round since it has Pre-outs and 5 x HDMI in.

What I also find interesting is that Onkyo bothered licensing Audyssey MultEQ XT for dynamic EQ'ing, but then opted for TLP instead of ADP for dynamic volume. I'm assuming licensing/fees issue made the difference, or perhaps some exclusivity deal between Denon and Audyssey for ADN shut Onkyo out of ADN for now, but I'd like to hope there's some technical reasons Onkyo chose.

EDIT: Based on further reading it seems TLP is not a dynamic volume level technology, but rather a process for maintaining sonic characteristics of a movie's THX "reference volume" but at lower volume levels. I guess the Onkyo TX-SR806 doesn't have a dynamic volume level feature after all.

As I stated in the 806/706 thread, I think you need to compare Audyssey's Dynamic EQ, not Dynamic Volume, to THX Loudness Plus. The description for the 2 technologies is identicle.

This is the description of THX Loudness Plus from their website: "With THX Loudness Plus, home theater audiences can now experience the rich details and ambient sound in a surround mix at any volume level."

This is the description of Dynamic EQ from Audyssey's website: "As you turn the volume up and down, Audyssey's Dynamic EQ maintains consistent bass response, tonal balance and surround impression"

The description of Dynamic Volume... "Set the volume you want. Audyssey Dynamic Volume keeps it there . . . Hands Free Listening is finally here, eliminating the annoyance of constantly changing the volume on the remote control"

Dynamic EQ was one of the things I really liked the idea of though, much more than Dynamic Volume, so I would really like to hear more discussion of Dynamic EQ vs THX Loudness Plus.

Just to add further to this discussion, I guess the thing that really concerns me is that Dynamic EQ worked in conjunction with Audyssey MultEQ. With THX Loudness Plus, is the processing going to take into consideration the effects of Audyssey? I wish they had left Dynamic EQ on there just so you could decide for yourself. On paper Dynamic EQ sounds much better than THX Loudness Plus.

Alright, makes sense after further reading. Kind of amusing, all these different "dynamic" sound processing and compensation techs now. Easy to get confused from a noobie perspective, but no doubt great talking point fodder for dim-witted sales guys trying to move product.

Now I'm more confused - take the Onkyo 806 for example - you've got

- Audyssey MultEQ XT (calibration I guess)
- Audyssey's Dynamic EQ (a dynamic EQ'ing tech)
- *and* THX Loudness Plus (a dynamic EQ'ing tech)

.. all in the same box? Outta control!

and then they don't bother to license audyssey dynamic volume.

From what I can see from their website they are only offering THX Loudness Plus on the 706/806. There is no Dynamic EQ on those models, yet there is Dynamic EQ on the 606. That has me concerned because Audyssey is one of the selling points and reasons for wanting to upgrade for me but if THX Loudness Plus work independently from Audyssey's EQ than it seems that Dynamic EQ would have been a better way to go.

I have already created a thread that covers this topic and more. Surprisingly, it has been disregarded by most, but I think with a little traffic to get it started, it will take off.
