I've recently jumped ship from PT to start using Logic 8. What a difference. Are the A-to-D converters in the Digi002 any good? Will I notice a discernable difference if I step up to the Apogee Ensemble or RNE Fireface? Or is the Digi002's A-to-D conversion comparable to those two products'? I'm using EVRE20s and some RNC Really Nice Preamps with RODE NT1s to record drums, and I'm recording bass direct from a preamp. Thanks.
