The 160A is by far one of the best and most used compressors around. For me it is the "Go To" compressor in a mix session for kick and snare. I also use it during tracking sessions on vocals and bass very often.
I currently own one 160A and one 160X. To me the 160A is the exact same as the classic 160x, minus the fact that the newer 160A has and additional xlr input and output as opposed to only having the 1/4 inch on the older 160X.
I highly recommend this compressor both for the seasoned pro (although they probably already know and / or have some) and for the new budding engineer. These compressors have been one of the best buys of my audio life. I am always looking for more of these puppies!
