Another CDSM recommendation here. The Ampex collection should be good with simple choices for multitrack and mixdown/mastering purposes. I have his R2R and tapebooster libraries and there are a ton of options. Once you find the flavor you like, it's straightforward. The tapebooster works on anything.
Okay the Ampex Collection looks to be what i'm going to grab, i use the free ATR on almost every record i do, but i must wait for the price reveal of the new Pink compressor before i make a decision. may be the last purchase i make for the year(newlywed)
I do have the TB Reelbus also and was using it before i fell back into the Nebula world
