Cool. Thanks.

Sounds like you have to have an extremely competent installer / calibrator for DIrac to really shine (just like everything else). An 11.1 Triad system should easily be able to show off what it can do. But having been to a number of CEDIAs, the rooms are not ideal, etc (but then again, it is 'room correction').biggrin.gif

Thanks!

DId you get over to the Pro Audio Technology set up (PHC)?

There are more than a handful of [op amps] that sound so good that most designers want to be using them as opposed to discreet transistors. Dave Reich, Theta 2009

We have 12sm for front LCR and 8ai for front height LCR.

Surrounds are all 26im and we use the 25ica for height and top. All active.

The room is 7x5x2.3m approximately.

The 8ai is a superb speaker for high end surround and height duties and still quite compact. In the uk we can often get away with it for front LCR given our relatively rabbit hutch sized spaces!!!

Interested in opinions here.

I am sure this unit has to sound A LOT better than the CEDIA demo. It was awful! The soundstage was "pinched", the bass was WAY out of control, in general, the group I went in to listen to it with were extremely underwhelmed.

Big Badda Boom! No quality at all whatsoever!

Still on the lookout for a better pre pro - haven't found it yet. Still looking...
This one thing that bothers me. Listening to a DEMO in an unfamiliar room setup by someone for their preferences is certainly not going to sound good to the listener. I DEMO'ed all my processors in my room setup to my liking. The only ones I could not get my hands on unfortunately were the Trinov and the JBL Synthesis. That being said, it far out performed the likes of Krell, mcintosh, Denon etc.

The point is that the unit is completely customizable to 'YOUR' preferences in regards to the room correction and sound stage setup. If you are really serious about a processor , I suggest you bring it home. smile.gif

Agreed. You should always audition the unit in your own home if possible. However, no demo should sound bad or off-putting. Especially one done by the manufacturer.

I would love to do a side-by-side with units from ADA and Theta. My guess it would come out with Datasat lacking a bit at the moment.

BTW: They do not make their own amps. You would be surprised to know who does. Saw the amps at the show, and saw them again in a couple of other company's designs. Finally found the company who actually makes them - and they keep the better tech to themselves.

Yes, Datasat are very proud of the fact their RA amp line were Morris Kesslers best amp design to date.

I used to own the ada crm4 and the Datasat RS20i is quite a bit better. Much more fluid and dramatic. Whilst maintaining an air of sophisticated refinement like you find with say Meridian offerings. And im still to get Dirac running.... The raw processing is just brilliant. And when Auro is implemented it will be that little step better.

Except they're the older design - also used by CAT and several others. BTW you can get them from ATI much cheaper!

ATI's 6000 series is a huge leap above, and again much better pricing...

An Interview with Morris Kessler - designer of Datasat amplifiers
The new Datast amplifiers were Mirris Kessler's last amplifier creation in which he applied new design features never used before to make the Datasat amplfiers very special and unique amongst his long line of creations.
In the last 40+ yrsMorris Kessler, ATI's president and chief sdesigner has been building amplifiers he has created near-ledendaty status. Not only has he built a half-million amplifiers for his own and other, often better-known companies, he also designed and manufactured the worlds first high-performance 5-channel 7-channel & 16-chanel amps. To say he's good at amplifiers would be a masterpiece of understament,

He was sitting over at the ATI booth during CEDIA showing a much improved, and less expensive, design.

Also heard about the new and exciting tech in the new Theta mono-blocks and what is coming down the road... Exciting stuff!

Well there is no denying that the AT6007 does read slightly better on paper. 128db snr as apposed to 127db on the RA. And 0.03 THD as apposed to less than 0.05THD on the RA.

Looks like I'll have to put an RA up against the AT6007.

Gents, the Datasat amp is based on the CAT amp from 5 years ago. Morris puts the best parts and highest performance into his CAT designs, because those installations have significantly higher demands for amp performance.

Morris developed several design characteristics for the CAT line that are now becoming common in his OEM amps, but I have to repeat that the CAT amps are superior to any others leaving that factory- by his design, not marketing.

I was in DATASAT booth Friday and Saturday and thought Saturday was much better.

DATASAT was used at Procella. Storm hardware was on static display. Presently no room correction and was told they (Storm) will roll their own regarding correction.

DATASAT was also in Wisdom room.

I am looking to purchase either a Datasat system or build my own HTPC going into a Trinnov system, at the moment it seems the Trinnov system sounds better based on peoples comments on these forums. I have read somewhere someone mentioning Dirac systems could surpass Trinnov correction with there new systems called Diract Dimension can anyone confirm this systems works similar to trinnov. Im just looking for reasons on which path to follow either the HTPC option or getting a Datasat system.

There are pros and cons to each approach.

No doubt about it the HTPC as pre-pro sounds amazing when you use digital out of the HTPC into a multichannel DAC. I wrote a blog article on this recently and have it up and running in my showroom in the SF Bay Area which features a HTPC with 16 channel AES out into a couple of DACs feeding a 12 channel Procella Audio system.

HTPC into an ExaSound for upto 8 channels (currently playing with that configuration now) or HTPC into a Trinnov via AES for up to 16 channels will give you some awesome sound quality.

A drawback is the lack of post processing modes such as DTS NeoX and the forthcoming Auro 3D. However you do have Trinnov remapping.

I would also say that you are kind of limited with sources if you go the HTPC route. JRiver, which you would need to use for this approach, is also reasonably complex to setup and optimize. Furthermore working out how to properly calibrate your audio and video is a challenge when using a HTPC and there are all kinds of little things with video especially which can screw things up.

Based on my experiences so far I would only recommend the HTPC as pre-pro for the hard core enthusiast. I am working on locking down a HTPC JRiver 'image' that I can offer up to less hard core enthusiasts as a HTPC/DAC/Setup package but still a ways to go before I launch that.

Was Wisdom still using their Audyssey EQ and crossover box? I get the point of active crossovers, but it would seem to be better to do that all in the Datasat to avoid additional A/D and D/A conversions (unless their Audyssey/crossover box can be set to just do crossover function in the analog domain only).

Yes it looked like it, at least it was in the rack below the DataSat

Amirm commented on that a while back as I recall he tried very hard to get the JBL Synthesis EQ to drive the Wisdom speakers, but he couldn't without the Wisdom Audyssey EQ/Crossover box. It would seem that anyone looking to get some Wisdom speakers would likely be looking at using something like the Datasat, ADA Reference, or Trinnov MC Processor in their system, so it seems unnecessary and counter-productive for Wisdom to not share the details on the crossover settings.

Thanks! It does seem silly for Wisdom to lock themselves into a single solution. OTOH, I should think that a clever integrator would be able to measure and develop a set of crossovers using ARCOS/Trinnov/Datasat etc.

That's a bummer. As thebland noted, looks like the ultimate processor package is the Datasat with the Trinnov MC (and for good measure, you can top that off with high end DAC's)

But why not make this easy for integrators? I would think they would more than make up for the loss of a few Audyssey/Crossover boxes by the sale of more speakers by simply making the crossover data available (plus giving the added benefit of really allowing the speakers to shine, as many don't feel that Audyssey is the best room correction platform, not to mention the additional A/D and D/A process of their current solution).

Our wisdom demo room runs off the RS20i plus a pair of RA7300. Very easy to setup with or without assistance from Wisdom although they were happy to discuss with us of course.

A drawback is the lack of post processing modes such as DTS NeoX and the forthcoming Auro 3D. However you do have Trinnov remapping.

I would also say that you are kind of limited with sources if you go the HTPC route. JRiver, which you would need to use for this approach, is also reasonably complex to setup and optimize. Furthermore working out how to properly calibrate your audio and video is a challenge when using a HTPC and there are all kinds of little things with video especially which can screw things up.

Based on my experiences so far I would only recommend the HTPC as pre-pro for the hard core enthusiast. I am working on locking down a HTPC JRiver 'image' that I can offer up to less hard core enthusiasts as a HTPC/DAC/Setup package but still a ways to go before I launch that.

Not to drag this OT, but were you able to get a multichannel application of Dirac to work in this setup with JRiver?
