Reading Amir's review of the Paradigm PW-Link I wondered if there are any preferably affordable digital in digital out boxes like that Paradigm unit, but without its failings (I am not interested here in its other functionality). The MiniDSP is a well known and often used little box to upload REW correction curves to but it only has analogue in and analogue out, so you add both an ADC and a DAC to the chain, and not great ones at that. What I would like is a little box in the digital part of the chain that can do dsp room eq, preferably automatically, but I am OK with uploading REW correction files. I am currently using an Antimode 8033 to equalize my subwoofer and I am so happy with it that I would like to do the same for my main speakers. Right now I am trying to set a number of parametric filters for my RME ADI-2 AC, and that will be enough for the worst peaks, but something more sophisticated would be nice. In my home office I only use my desktop computer as a source, so there the Equalizer APO was enough to upload the correction files to. In my main system I have four (optical) sources so I would like to insert the unit right before the DAC. Does anyone have a suggestion, or is the market not yet ready?
