Am I getting it all?

I'm wondering if you have just run into some of the multitude of not so well done LPs. You mention that some of your LPs playback better sounding than your digital source. I don't find that so unusual. My old BAT CDP often gives some of my LPs a run. From your description of what you have done setup-wise I think you've got it about as good as it's going to get. I run my XV-1s at 100 ohms and I'm usually around 1.8x - 1.9x for VTF. Never heard your pre or the PS Audio. It may be that you've max'ed out on the Scout, but make sure you're good with the other components in the chain before you decide where to go. Maybe if you can get more specific about what you think is missing?

Agree with Ncarv...a very good analog front end should smoke even superb digital. I'll take my Linn LP12, Koetsu Black, and Ear 834 over the digital I've had in my house most any day (at least on classical)--and that includes the EMM CDSA, the Linn CD12, and the GNSC Wadia 860, all of which are about as good as digital gets. I used to use a passive pre years ago, and concluded, after some experimentation, that an active tube pre just sounded more musical. Don't really understand why, but, like Plato, think you may want to start there.

One problem with vinyl is getting high quality LPs. Are you listening to many 180 and 200 gram version and 45 rpm versions? There are many new jazz reissues on 45 rpm that are stunning. I've got several of the Tacets and agree that they're wonderful. The Count Basie reissues and almost all Pablo reissues are wonderful.

The fact that your "best" experience to date is with the Tacet vinyl makes me think that your front end can deliver and you just don't have the best LPs. There's not a ton of great new classical reissues out there, so if that's your preference, then you've got a tougher search. Lyrita, Mercury, old RCAs, Harmonia Mundi are some of the better classical labels that had good pressing back in the old days.

Happy hunting.

I think Dan-ed asked the key question. How does digital better the vinyl? If you say better bass or upper treble, you may be missing the point. You may at this stage be listening too critically. All the setup suggestions above could be part of it, but I thought what you said about the one record giving you the most intense experience yet was key. That's exactly where analog smokes digital. When you first get into vinyl, and you're tweaking things, it's easy to lose sight of the big picture. Listen instead to dynamics, soundstage, and an overall more organic or human presentation. Step back and try to forget the analytical for now. Kinda like those 3D pictures that at first look like nothing but as you unfocus reveal themselves.
I have a really nice digital setup but I find I rarely pull out a cd or sacd. That emotional connection I get much more with lp's. You may find a gradual shift in preferences too.

I agree with all, try an active preamp. All the passives I've heard sound like there is something missing from the music.
