Digi-Rack plug-ins' effect on sonic qualtiy?

[imp]

Hello,

Quick question... has anyone ever noticed a sonic degradation while running audio through any of the Digi-rack plug-ins? We run all our audio out to analog land and mix inside an analog mixer with all analog eqs and compressors. But sometimes it is tempting to ALSO throw a Digi eq on a track before sending it out to the analog console, for extra eq control. However, the concern is that the audio may become digitally colored in some way by passing through these plug ins. We have not had a chance to really test this yet.... minor degradations are often hard to hear on just one single track, it's really a cumulative effect. So, just wonder if anyone has any experience with this. We always avoid the plugs when possible to reduce any extra digital effecting, but occasionally it's just so convenient to use a plug-in here and there... just wanna know if we are sacrificing any audio purity by doing so, at least in the opinions of other Digi users. Thanks - imp
