Get this one at closeout price. I had to haggle to get this price 2 years ago. Fosgate tube phono at musicdirect

Under budget with $500 to play with tubes/interconnects/power cord.Discontinued but you will still get full warranty support from distributor in the event anything happens. Best 2k value for a top notch phono stage.

I second the Allnic H1201. I love mine and it was a substantial improvement over the JLTI which it replaced (which was quite good and an amazing value, frankly). I've also heard great things about the Herron VTHP-2.

I confess I have never done the requisite head to head comparisons, but I do know something about circuit design and quality of execution. Unless you MUST have a solid state phono stage, the K&K Audio Maxx phono stage will smoke the ones you've listed, but it does use tubes. The cost is right at or a bit above your upper limit of $2500.
