Hmmm, I thought those extra power amplifiers were there so one could bi-amp the woofers and tweeters. It appears my two-year-old amp isn't enough anymore. Need more channels.
I did notice in the article the emphasis on getting back to stereo...
"[I]Because Halo generates a coherent spatial sound, you can be assured of a high-quality downmix. The 'exact' mode function ensures ultimate downmix performance where, as in TV re-purposing for instance, maintaining the relationship between the original, upmixed and downmixed versions is imperative.[/I]"
I guess that's for us.*
