I use quadcurve for every track but if it were to be switched out for the LP EQ and if the LP EQ had a convenient low bandwidth switch (which I think it already does), I think I would be better served. LP EQ is a better product and if any EQ plugin designed for Cakewalk should be further developed it should be there... Also, with the intel I9 that I have, I am not really worried about reaching the ceiling of my processor by adding CPU hog plugins. My most complex songs barely even move the indicator lights on all 12 cores. Load balancing works really fantastic! It is nice to see that plug-in load balancing made it into CbB... :)
The LP EQ is a Linear Phase EQ, which are often used for Mastering.
