I suppose one man’s endgame is another man’s entry level.
I don’t know what SOTA stands for but in any case I would imagine that audio speaker technology would not have changed that much in the past 20 years. I could be wrong but the tweeters and midrange drivers in my Hales are still current and available in outfits like Madisound. I changed out my tweeters for Seas Millennium which match the midrange drivers which come with the Hales. I don’t know if the woofers are still available but I bought a pair of spare woofers years ago just in case. I also redid my crossovers with better quality parts and rewired them as well. I think my Hales are keepers.
