One by one, the name brands of audio are confronting the difficult issue of whether or not to take their products online.

Trying to get a grip on where the new high-end audio formats, DVD-Audio and SACD, might be going? A logical place to start might be to check with the factories getting ready to crank out the discs and see how the orders have so far stacked up.
