The only dedicated amp Ergo (or Precide) ever made for the Floats runs on +900V which is only 50% higher than the Sennheiser HEV90 and actually less than the KGSSHV. In theory the amp would be capable of swinging 1700Vp-p but given its design it would be far less. It's SRPP with ECC81's which are both huge problems, the SRPP doesn't work into a capacitive load and the ECC81's are driven to breaking point. A KGSSHV, Blue Hawaii or a T2 will have no problem matching these numbers but the gain could be too low and the output protection resistors would have to be defeated. They limit the current into the stators which is never an issue with Stax drivers but the Jecklin drivers will need more current so the resistors have to be changed.
