In 3 of my current cars I have installed Sony MEX-DV2020's. These car radios play multi-channel SACD's, DTS, and Dolby Digital. They also play conventional stereo CD's. It contains very good electronics and lots of power and truly functional multi-band EQ adjustments. It will also play video DVD's!
Sony has sold lots of these and the previous MEX-DV2000. But it is sad to report that only DVD-A has made it into some OEM car radio systems.
I can pop in the multi-channel SACD of Gaucho, crank up the volume, and drive down the road with a huge smile on my face.
I will also play the DTS or DD multi-channel tracks on a DVD-Audio disk, but since most will not play with the mere insertion of the disk into the player, (I must click and click around on menu settings I cannot see (in a car without a video monitor) it is a huge distraction, and it does not always work.
My argument is not with the quality of DVD-Audio's sound but with the very poor and inconsistant way in which the audio is written on each disk. There is no standard; gerrrrrrrrr!
But the fact that DVD-A disks may offer higher levels of audio above 20,000 cps is of no interest to me. The fact that I will and have purchased tons of hybrid multi-channel SACD's is because they sound great to me AND I can play them with ease in any hardware I own.
I would purchase many more AIX recordings if they were offered as hybrid SACD's; that is a fact!
