Actually, to be more specific, I have both units but here is how I prefer to use them. In my home studio I record two channels of bass:
1. Bass --> Markbass Compressore --> Ampeg PF-20T (transformer-balanced line out) --> Millennia Media HV-35P --> RME Fireface 800 --> DAW (ProTools)
2. Bass --> REDDI --> Millennia Media TD-1 (HV-3 mic input) --> RME Fireface 800 --> DAW (ProTools)
For the second track, I can definitely bypass the REDDI and directly plug into the TD-1, but somehow I want to keep the REDDI in the signal chain. I admit I have not done any A-B'ing so far with the same looped track to see how the two options differ (if at all), but I am just lazy at the moment to try and would like to hear some opinions prior to going through the hassle.
I will definitely do an A-B though, and will share the results with you here...
Cheers,
Alper
