I've had a Schiit Saga -- an excellent, very neutral preamp. The only problem I had was that it is unity gain. My setup needs a preamp with a bit more gain. I ended up switching to a Schiit Lyr 3 which has switchable gain. It has only one or two inputs (depending on whether you get their DAC or phono card installed) but that's fine with me since my only source is a streamer. I also got an excellent headphone amp with the Lyr.
I also think, in terms of sound quality, that Schiit is well past your 80% mark. Sure there is always something better, but at what cost? Or, you may just prefer something with a different sound profile -- more tubey, etched highs, etc., but that's all a matter of taste and not necessarily "better" (for anyone but you.)
One thing about Schiit is they have a 15 day trial period. You can return items like the above with only a 5% restocking fee. Or, if you want to try it out for a few months, Schiit has a really high resale value on the used market and items typically go quickly. So you can try out either a Saga or Freya without much cost if you decide to move on.
