I'm going to build a couple of active 4th order L-R crossovers, and i was wondering... Would there be a great audible difference between using TL071/072 opamps and OPA227/2227 (at unity gain) ???
If it's really worth using OPAs, i'd like to know. Those free samples sure do look "tasty" :) (rather than paying ~3$ a piece here)
