In the Thread: Sound of line level filters

Post Subject: Sound of line level filtersPosted by noviygera on: 3/1/2012

I thought that a digital crossover had a negative impact on sound quality -- especially for use between a midbass, midrange and tweeter channels. So I made an experiment a what I learned was not expected.
I used my mid horn and two high pass filters in front of my Rowland amp for a shootout -- one digital DBX Driverack, another line level passive RC. Simple 6 db/octave at 200hz high pass. Listened to different records...
The digital filter had an obvious advantage in the attack and dynamics, but suffered from dry decays, lack of delicacy, and transparency. The passive filter was much more natural, transparent, with sophistication and nuance but suffered significantly, LACKING attack and dynamics. So both filters are incompetent in my opinion, in own ways. Are there other filters that get both the attack and decay right? Maybe passive RL or active line level like the Marchand?
Anyone has good experience with 6db/octave high pass filters in front of amps?
