Best phono DIY kit


I’m thinking my 12AX7-based Croft phono pre may be improved upon. Are there any kits out there using different topologies which would kick things up a level? MM only and/or SUT is fine. Tube preferred. Budget up to $3k. Thanks.

Too bad the K & K Audio kits are no longer available, that would have been a no-brainer.

This one looks interesting though:

Although a little above your price point Audio Note has a nice kit as well:

Hagerman used to have a few more kits but evidently this is it now:

You’ll have to source everything but the PCB for that one.

Bottlehead might be an option as well:

Thanks @clio09
I think I was looking for something a little more esoteric.
