Best Preamp under $5k??

I think around $5k is the reflection point of value/price ratio for preamps--or mostly any audio equipment maybe except speakers--where beyond this point, you would have to spend thousands more to improve just a little. What is the best preamp under $5k--tube or solid state?? Some popular ones are sf line 3, bat vk5i, arc ls25, simaudio p-5, plinius m16. Personally I have a cj pfr which I like quite a bit, but sooner or later it will be upgraded...
