    I am all for greater understanding and your evangelism for High Resolution Audio. I experienced DVD-Audio when I bought an Acura TL in early 2004 and listened to the disc that you produced for that vehicle. I immediately went and bought a DVD-Audio player, which I still have, and deployed two 5.1 setups in the house I was living in at that time. I used the Acura disc to show anybody that would give me 5 minutes, how fantastic HRA was (96/24 stereo) and surround sound.

    I have since moved and am setting up a 5.1 system in my current house and I will continue to demonstrate HRA to anyone who will give me 5 minutes when they come to my place.

    As I was reading your email yesterday, it struck me how ironic it is that you provide your daily information in a written/read format when the topic is about audio. I encourage you to consider using an audio format occasionally, with audio examples when possible. I understand the logistics and greater time/expense this would entail for you though that may be offset by the greater audience you could reach. I am not strictly speaking of a podcast as much as an audio version with example files to further make the points of your post.


    PS I suspect you use voice recognition at the moment based on some of the contextual inconsistencies so you may be part of the way there 😉

    PPS I realized it was Elliot Scheiner that produced the sampler DVD-Audio disc that came with the 2004 Acura TL. My apologies for the error.
