The UA 610A. It is a super powerful plugin. I came across either a video or a subreddit where people were describing using a Universal Audio 610A into the Neve 1084. I had dabbled with this plug-in in the past but never took the time to study it— and boy was I wrong. I threw it on some vocals that already had the Neve 1073 printed. I put the LF (Low Frequency knob to -6, one song I left the HF knob that 12 o'clock the other +6. It added a super clean vintage Sheen to the vocals that I wasn't getting from my Neve 1073. Since I'm using a tube Microphone I was actually getting a lot of detail saturation especially in the high end, This UA 610A preamp smoothed out all of that in the best way. It brought a richness to the vocal I've been looking for, for a long time. Try it out you might be surprised.💯
