Well, I finally finished my discrete Class A XO project. I used my own design discrete op amps, based on an early Spectral design modified with Nelson Pass inspired JFet output stages (instead of MOSFET stages as originally used by Spectral). I am using 4rth order Linkwitz Riley filters for both HP and LP filters and the drivers integrate smoothly
Took out the gyrators as I really did not need parametric EQ with the Voxative drivers (switched from the Horn).
System is now sounding better than it's ever sounded. So that confirms that the active XO system has merit in principle, and the class A discrete designs in practice.
