I'd better start saving money for the new hybrid
If they don't increase the price significantly, I will definitely be one of the first adopters, as T800 is a price/performance king for me still (even after trying the S8F, TSMR5 and Moon S8.
IMO its not necessary to implement some beryllium coated driver as the usual budget ones are often just a marketing gimmick and spraying the plastic driver with a few molecules of beryllium won't make a huge difference.
Having solid beryllium driver or at least thin layer of beryllium on top is different story, but those won't cost a few bucks. Graphene coated drivers are good for bass - think IT01 or Blitzwolf ES1.
At the end, cheap well tuned DD will sound better than peaky expensive beryllium, in m book...
I'm just hoping the hybrid is gonna sound at least a touch more neutral while keeping the technical abilities of T800.
