Watch out that a 90 degrees phase shift can cause essentially unbounded increase in peak levels. Worst-case signals are things like bright saw or square waves that theoretically cause peaks to become infinite (in practice they will be finite due to digital audio being bandlimited, but they are still get huge). This in turn means you’ll potentially be hitting the limiter very hard, causing distortion as a result.
Such phase shift also tends to make a mess out of transients. You can hear this cle…
