I'd like to get either a multichannel preamp like Focusrite Octopre or a single channel strip. Required: digital output(s) Nice to have: compressor tube multichannel Not so required: eq Price: < $800 roughly. like to buy it used if possible. Must work well with U87, Rode NT1000, ADK Vienna Edition, AKG Solidtube and SM57. Will be plugged into Digi 002 rack so preferable input would be ADAT lightpipe or SPDIF. What are pros and cons of different alternatives? Anything that come to your minds are appreciated. P.
