Thomann has started to deliver the evo in Germany (and Europe I guess). I got mine today. I was very pleased with the tamed highs which aren't sharp anymore. But I was disappointed because the bass wasn't as crisp and punchy as on my old 681.
Some guy on a german forum found out that superlux put an additional felt disc between the driver and the foam-pad. He suggested to remove it:
After I removed it (it's glued slightly) I had the feeling the old 681 is back. Fast, crisp and punchy bass that just makes great fun, the sound was more airier, bigger stage, more dynamic but there are the harsh highs back, too. I will leave the felt away because I really didn't like the clogged sound with it and live with the highs until I find a possibility to mod it.
