I'm currently in need of a budget hardware compressor. I already have a DBX 160A and find it to be useful. But now I'm in need of another channel of hardware compression. I'm not sure if I should get another 160 or try something else. The only other quality comp I see for a good price is the RNC 1773. Are there any other good comps out there in the same price range as these units? Which do you guys think is a better the 160 or the 1773? Whatever compressor I do get will be used for tracking to tape (by tape I mean hardrive). I'll only be using light compression, just to level off some peaks. It will be used on Guitars, drums, vocals, ect. So I need a good all around compressor. Also, what's up with all the different versions of the 160? What's the difference between the 160A, 160X, and 160xt?
