In Reply to: slow/fast roll-off filters pre-ringing in real world? posted by dave789 on July 17, 2015 at 08:36:35:
I have some limited experience with a Heed Obelisk DA dac which has 3 filter settings.
F1 is 'linear phase soft knee'
F2 is 'linear phase brickwall' (default setting)
F3 is 'minimum phase soft knee'.
It's a very good sounding unit, used with the Heed Obelisk DT transport.
I've used it in my 2nd system (headphones only via a good amp) and in my main system.
Recently I tried changing the filter from F2 to F3. At first I found it hard to hear any difference; but on further listening, I noticed improved tonality and a more natural sound. So I have left it that way, and the Heed now remains in the main system in preference to a Resolution Opus 21, Luxman DA06, and Astin Trew At3500+. I find my Accuphase slightly better but the Heed is now closer with the F3 filter; the Accuphase stays in the headphone system. Both sound gorgeous.
My limited experience suggests different filters can make a meaningful difference. But I'm sure personal taste and system matching are major factors.
