Kt90 Upper midrage forwarness
Hello,
Running Rogue Apollo amps with EH KT90's
Im getting an Upper mid range that's out of balance and Forward.
I have had other rogue amps with Kt88's without the Forwardness.
Considering going to EH kt-88's or Gold lion Kt88's
Have High efficiency speaker which is adding to this.
