One thing that concerns me is if the RS20i time delay incremental adjustments are fine enough. The Rane units allow for adjustments to hundredths of a millisecond.

Thanks and best regards,

I had Carl Huff help me align the multiple drivers in my system. Dirac live did a great job of EQing them as well.

Mike Schurzak (to be corrected) from Datasat visited Prometheus to discuss auro and yes atmos upgrade path for that room. YOUTUBE Post 2 here shows how the datasat adapts to the different speaker configurations while communicating the correct edid to the blu ray player.

I didn't wanted to post Datasat vs. Storm Audio because both brands ooze quality and rock in .

However a comparison between thse 2 sets would be something useful.

Datasat has a storng Processor, the RS20i with the lateast (and the oldest) decoding we can ever demand, and besides it has empty slots for the future. In terms of Amps, their amps are Class A circuit.

Storm Audio has also an amazing processor with lots of decoding (not so much for the old ones we need once a while) and in terms of Amps they went to Class D.

Well Datasat Amps are rated like 300 watts per channel, and the Storm Audio provided us a strong 350 watt per channel.

Question is:

- How does Class A vs. Class D compares in terms of performance?
- Is this the technology of the future or Class A will continue to rule?

P.S: Athem Statement Line of Amplifiers are truly remarkable also and i don't know in terms of directly comparisson if they are even superior to Datasat RA7300

I think from a company size, pedigree, ongoing support, and product viability the datasat will outsell storm 2-1, the company is largfer and has a huge client base, their software upgrade record is best in inbdustry. The current vs future offerings Storm appears to have zero advantages, class a sound is rich and warm class d does not offer velvetty upper range like class a.

I also share that opinion right now.

To make Auro 3D there is the need for a ceiling speaker, so te best is to combine for example a Datasat RA7300 with a RA2400 right?

Or for example an ATI Signature Amplifier, guess the quality should be the same with their Signature Line.

As I know Datasat Power Amplifier RA-7300 & RA-2400 are the same units of ATI AT-6000 Signature Series , only few things differ from original designed . The ATI AT-6000 Signature series suppose to be Class AB designed same as AT-3000 Series . Actually we can't say which designed Class , A ,AB ,A/AB or D will made sound better , it depend on and varies from one to the another brand .

I actually think the Datasat units are a little different to the ATI signature series - at least their rear architecture is different, their configurability is different, some of the internal components are apparently meant to be different, active cooling is apparently also used on the Datasat units, their specs are a little different and their prices are also quite different!

Yes, I'm agree with you that price is extremely different between ATI AT-6000 Signature Series and DATASAT RA-7300 & RA-2400. The main reason is Manufacturer cost might be lower than marketing cost

The Datasat amps were said to be class A circuit by somebody else in post #1713 . I just questioned that statement. Probably should have put in a quote in the first place to avoid any misunderstandings.

They are AB. if they were class A they would run so hot. Mine runs quite cool.

We'll I have been outed on another site so I shall post this here also.

I have been lucky enough to be running Auro in my Datasat for the last week.

And Yes the Auro update is stunning! And it also includes the Dirac 2 update.

I have spent the last week listening to various formats and it's all mind blowingly good.

2 channel music sounds somewhat similar to using Trinnovs remapping. Rather than sounding like you have 2 channel content being played back in multichannel, it sounds much more like you have the best imaging pair of stereo speakers you have ever heard.

Then of course onto movies. I watched Divergent yesterday, and Auro helped turn what would have been a very mediocre film into one that was gripping, the atmospherics created by the upmixing just pull you into the movie.

2 particular stand out film scenes for me so far have been the sand storm scene from Mission impossible Ghost Protocol - when the sand storm hits, the sound is so enveloping it's almost disorientating, literally bing pummled from all directions by sand. And it's as tho you can hear each individual grain. The clarity is stunning.

Then there is the Hit Man David Foster Blu Ray concert. I was showing this to my dad yesterday. First we played back with no processing and then Neo x. Both sounds great. But as soon as you engage Auro they sound flatter than a pancake.

One of the first things you notice with Auro is that the audience really is all around you. The cheering and clapping is everywhere. Then when the concert begins you really get a sense of the location it was recorded in. Ie, a large hall. My small 7m x 3m x 2.56m cinema room was transformed into an auditorium. Ceiling and walls gone. Just an expanse of sound.

I won't go showing screen shots just yet as we are still in Beta phase, but it's really simple to use. You have 4 presets. Small, Medium and Large room and then speech. I have small room selected. I'm guessing these control the amount of reverb applied.

Then there is a fader for between 1 - 15. This tells the system how much info to put thru to the Auro height channels. I find 10 is about right for music. And you can easily go up to 15 for films. It does something to the bass also. With the 15 setting sounding too rich for music. But for films it seems to increase the amount of punch delivered from the subs.

There are a few issues to be ironed out. But as this is beta that is too be expected. Most issues are down to installation or moreover incorrect installation instructions.

But for me, the biggest issue is with 2 channel PCM or DD tv / film content. The auromatic upmixer doesn't really handle this too well. It doesn't extrapolate the speech into the centre channel. Almost like listening to a film or tv thru a music upmixing codec. But it also sounds a little out of phase. But again I'm sure this will get sorted.

All in all, I'm super happy. Well worth the money. And with more Auro encoded content being released things can only get better.

What changes come along with Dirac 2? Will Dirac now calculate channel delays and levels?

Sonically there is no difference between Dirac 1 & 2. It's more a change in pc software GUI. And I believe it will output sweeps rather than PN for calibration which will speed the process up.

It was mentioned that Dirac 2'will calculate delays and levels but I'm not sure right now as I'm waiting my Dirac 2 pc software. But I think the auto delays and levels don't work on the theta with Dirac 2. But I could be wrong and am happy to stand corrected.

Well congratulations but don't think for a moment that I was going to let you Brits upstage us. We upstage YOU with the world's first Quested AURO.

MORATORIUM LIFTED-FIRE AWAY JEFF!!

And new AURO firmware coming by weekend.

For now I'll have to make do with the worlds first B&W diamond 13.4 auro setup. Being British I should perhaps have questeds, but I don't require the high spl levels the quested put out.

Now I can talk about it!! I'm very excited about Auro and djmick's early review of such. Except, until I get final installation, there's little to discuss. Next Wednesday, I'll have all installed.

Should be fun! Thanks, Peter!

The latest RS20i firmware is V1.03.02 RC2. That is the final version for the AURO/ Dirac Live v2 upgrade. I chatted with Datasat Engineering on that very topic earlier today. Check your RS20i to verify that what you have.

Sounds like I am good but how do you navigate to see the latest firmware version?

Thanks!

Quick question if you don't mind, what diamonds are you using i.e. generation and models? I'm a diamond user myself thus I'm curious what you are running and if all the speakers are diamonds, well at least the main plain as B&W haven't yet used the diamond tweeters in any of their ceiling/wall speakers, not even the CI800's unfortunately as that would be great for timbre matching the 800 diamond series for Atmos and Auro installations.
