I'm looking to buy a couple of the dbx 160 compressor/limiter series. I've heard the dbx 160x and the 160a, and found the 160x to be superior. I've never heard the original dbx 160, and was wondering if it is considered the best model of the 160 series, or if the only difference between the 160 and 160x is the VU meter being swapped out for the LED meter?

Thanks,
