My system consists of a pair of Oris horns with Fostex drivers and separate tweeters. I have a pair of TAD 15 inch woofers that are separately by amped. The horns and tweeters are run by a western electric 300 B clone and the woofers are run by a sumo Polaris solid-state amp.
I am very familiar with Vander Steen sound having on the pair for numerous years and I have heard your speakers numerous times as well. I'm sure your system sounds very very good and it will probably do a few things better than mine but likewise my system will do a few things better than yours. If all of these advances were so great your modern system should completely obliterate mine with it's 80-year-old technology. Rest assured that would not be happening.
I feel the need to try and correct these types of statements because I feel that they are driven by marketing simply to cause people to spend endless amounts of money and never exit the merry-go-round.
