Thanks Chris, your text is very much appreciated
So far I have avoided dsp's of emotional reasons (I use only analogue sources and SE triode amps), because not beeing able to "see" and understand the complete signal chain makes me a bit nervous. I´m currently going 3-way having low-level 1st order LP-filter at 350Hz (bi amping), so going going dsp filter will require tri-amping and a 3 way DSP-unit. Hence a rather big change. Any suggestion which dsp-unit to try?
Just to understand you clearly.
With balanced gain and correct delay (and moderate sound levels) I could actually remove the 6K3 hz filter between Mid and Hi, without worry destroying the fragile HF diaphragm in the 4592Nd?
