I can only compare my previous Orpheus with v2 upgrades against my new Zeus with v3 upgrades, here is what I wrote in my Zeus Thread:
- First thing I noticed was not the bass, compared to the Orpheus but the highs and mid-range. There is much more resolution. This was really the goal of this change. Keep the naturalness of the Orpheus but increase resolution. Imaging has improved as well. If you have an older pair of Daedalus, send them in for the new tweeters and mid-range (new 2021 mid-range). For the cost, no brainer.
