Hi i Just have two questions I have a small studio setup mainly for recording vocals/acoustic guitar... 1. I have currently have a warm audio tone beast pre amp and have seen a phoenix drs mark 2 stereo pre amp selling for £1000 (half price as new model is coming out) ..I'm just wondering if theres much difference in quality between the two pre amps ? 2. I'm.looking at getting a lexicon effects unit and warm audio compressor and mounting on patch bay, but I will need separate analogue to digital converter as my sound device (Audient id22 ) only has 2 inputs...can any one recommend a a/d converter up to around 4 inputs/outputs? ..I'm a bit lost as which are good quality but anything to the Audient level would be good. Thanks!
