I like the PSPMixSaturator myself over the Vintagewarmer and pretty much everything I've EVER tried so give that a try. There's a couple of tape settings, valve, and even digital sounds really good. You can pinpoint frequencies you want to soften and they come out better by some voodoo magic in that plugin. You WILL KNOW what I mean when you try every knob, something happens that brings back some kind of memory of records & tapes.
I also like the Soundtoys Radiator on drums and just a tiny bit on the mix will make a difference. If you are careful, you could add a lot of heat to some of the tracks or even the mix. The PSPMixSaturator with do a LOT though, almost like going back and doing a complete remix. Pretty good plug. I think it will come out better than the VintageWarmer mixed one.
