In the Thread: Sound of line level filters

Post Subject: Impossible.Posted by Romy the Cat on: 3/2/2012

Nope, sorry, it does not make any sense for me. The use of Rowland amp I guess is fine if it being use for testing of the filters. Still if you use high-pass for your midrange horn then what resistor does in your RC filter? A first order filter, regardless of topology and type, shall not introduce any "attack" changes and shall not change any “damping” or “softness” of sound. Similar to it: the digital filter shall not introduce any digital MP3-like compression. Something that you’re doing is very wrong or the way how you perceive the results is very wrong. Run RTA sweeps and make sure that you digital and analog filters introduce the identical slopes and identical insertion loss if you have any. If your digital filter has digital compression and if your analog filter changes sound in band-pass so much then something is very wrong in your entire experiment.
