So, are you telling me that I can get true DTS 5.1 sound!!?!!? Holy guacamole I'm in. I grew up playing keys and trombone and lots of jazz and classical and a bit of the popular stuff (because my friends made me). I'd love to hear the great sound that this system can produce.
Do you have a process documented for creating the DVD-A's or is it pretty straightforward?
There are a few applications that can author DVD-A discs - but unfortunately one of the Windows authoring tools, made by Cirlinca, has been discontinued, and the company no longer seems to be in operation.
Here is a good reference:
I fortunately acquired Cirlinca's product before they closed down (this occurred in the past two months or so) and I think since this format has such little interest nowadays, it didn't cover their overhead. It is designed for Windows, and can be run under a virtual machine in OS X under VMware Fusion, etc. Another application, Burn!, is an OS X native application that has not been updated in some time, is open source, and free., but is not as powerful as some of the others.
Cinlinca's applications focused more on on multi-channel music authoring a true 5.1 high-resolution DVD, where the others are mostly focused on authoring DVD discs storing 2-channel high resolution audio discs.
There was a trial version of Cirlinca's application available for download. I may still have it if you would like to test it. If interested, send me a PM and I search for it.
Regretfully, audio technology is going more toward convenience and profits instead of advancing the quality of the recordings. I am still waiting for the day artists release the multi-track masters from the recording sessions instead of having to rely on leaked copies. I do not mind at all paying for quality music, but do have a problem paying the same price for compressed, lossy, low dynamic range music when it costs the same or more than a Compact Disc at 44.1.k/16-bit.
HDTracks.com is a legal way to acquire high-resolution audio files in multi formats from a wide range of artist, including the recently released Led Zeppelin x Led Zeppelin (96k/24-bit), to classical music and jazz masterpieces. I believe artists such as Led Zeppelin have made their entire catalog available in high-resolution, and many Beatles material is available as well.
HDTracks is typically not in 5.1, but only high resolution, so it is good to listen to on your computer, as well as being able to record it on a DVD-Video disc that is playable on any DVD player, and a multisession DVD with DVD-Video and DVD-Audio formats combined.
I usually attempt to locate concerts of my favorites artists and generally you will get compressed music (not MP3 level compressed) but also get the 480p video, as well as your choice of 2-channel stereo, DTS 5.1, and Dolby Digital 5.1 on one DVD.
One modern artist I enjoy is John Mayer, and he has released much of his material in 96/24-bit.
Search for your favorite material and see what is available, as well as Amazon for pressed DVD-Audio or DVD-Video discs in concert. It will make the HK system really shine. (also, disable Logic 7 to disable the faux surround sound to hear the actual surround sound channels as the producer intended.)
