and lots of length to choose from, depending on where you place your separate amps
Thank you for reminding me of this type of connector. I remember that I saw it on the DATASAT and also other equipment. It saves space for sure, but I am not sure, what I shall think about it in the direction of electrical separation and interference? Maybe OK, but the connectors are relatively close together, however, this is balanced and should therefore be no problem.

In the sense of a new top of the line unit, I agree to Jonathan's thoughts. Modular or even PC based would be the way to go. Where I see the AD section as one important thing in hardware - at least of today and the rest in software, not on dedicated FPGAs or DSPs, on multipurpose processors. This would be really a paradigm change for the manufacturers and I doubt, they see it this way. However, I think this is the way everything will go. I don't know the DATASAT from the inside but I think this is also a computer, basically.

Just my two cents...

Correct, the Datasat and especially the Trinnov Altitude32 are basically PCs with customized Linux deployments that make them dedicated (and optimized) to their functions.

The more I think about the Altitude32, the more I like it. Just need to decide which car to sell first so I can afford it ;-)

Thank you for confirming my guess. Well, there must be software worth a car inside this PC.

A Linux PC with some standard hardware and some refinements is worth 2000 US$ in the best case. If Trinnov and Datasat are the best pieces of pre/pro equipment today and are much more expensive then the AVP then everything today is only about computing power, isn't it. But this is in fact inexpensive compared to something as the AVP, made of beautiful and heavy materials, engineered with lots of knowledge. I mean software is relatively easy to make. Sure, you need also a lot of knowledge especially for the audio side, but many things already exist. Decoders for all kind of material is already software and you can just buy it and use it in your own program code.

I am also sure that they needed years of development but still I have a bad feeling about DSPs in general. I can hear a sound improvement with my AVP when I switch off the DSPs and listen in 'pure direct' mode - at least for stereo sources. And now, the inventor of Auro 3D was asked in an interview, what do you think about the bad influence of DSPs on the sound and he answers: This is no problem.

You can find the answers on this question starting from minute 48 in this video http://www.areadvd.de/tests/special-...xpo-in-denver/

The interviewer speaks German but the interviews are in English. This video is from CEDIA EXPO in Denver in 2014. This is part of a comparison of ATMOS and Auro 3D, made by Lars Mette from 'Hollywood at home' company. May be also interesting for some to listen what the representatives of Dolby and Auro 3D say about their products.

There is also shown in the video, how DSPs are influencing a rectangle test tone, shown on an oscilloscope.

Well, I am having some headache, thinking about the reproduction of high end sound via a Linux PC and especially paying the amount of money for a middle class car for this PC... But, let's see...

Have you looked at the pictures of the rear panel of the Trinnov? There's clearly a regular motherboard in there, but everything else is clearly custom boards. So it's not just a standard PC with some minor refinements and a bunch of software added.

As a software developer, I'd beg to differ with what you're saying here. The type of software needed for a surround sound processor most definitely isn't trivial to write and I doubt they're just grabbing a bunch of public domain code and throwing it in there. Writing code for FPGA's is probably somewhat more difficult in some respects, but the algorithms used are going to be pretty similar either way.
