Has much changed?
Not by much and by a lot. The circuit is the same, it has just evolved (or devolved depending on who you ask) from point-to-point wiring (160, 161) to PCB (160x, 160xt) to surface mount (
160a). Parts, of course, change over time so that can have an effect on the tonality as well.
I have older
dbx 165a's that I love and use on almost everything, but I know guys that absolutely hate them. I know guys that have 160x's that swear they are better than 160xt's. This is patently impossible, they are identical units. I did compare one of
my 160x's to a buddies 160xt and they sounded different, it turned out his was way out of calibration. As soon as it was calibrated correctly, the two were indistinguishable. I've got a 119 that is the same thing as a 160VU, (just unbalanced) that I got for 40 bucks, as opposed to the 160VU that'll set you back 800 to 1000 bucks.
So, don't let the model numbers confuse you too much, if it sounds good it is good. dbx has been in business for 25 years or so. You end up with a lot of model numbers over 25 years
