Best turntable under $4000

I would look at a cartridge upgrade first.  I have the Blue and it is good but not the best of the four cartridges I own.  Denon 103, ADC VM760, Grado Sonata, and the Blue.  The others definitely beat the Blue in all parameters.  

You asked for the best TT in the $4000 price range.  Frankly, I don't think there is such a thing as "best" in the upper price ranges.  What you do have are differences that will influence your decision on one over another.  I would look at all of your choices carefully, find one that fires your rockets, and put your money into a better cartridge.  Do make sure the compliance is suitable for the arm you have or will buy before you send that backhoe into your wallet.

I agree the term ‘best’ is vague. And I think you should consider the analog chain - table (including tone arm), cartridge and phono stage. 
 

I believe you have an internal phone stage with your Rogue so I’ll focus on turntable and cartridge. First of all - I recommend only buying what you have listened too or can audition. Second I have been happy with Rega and most recently P8 with Ania cartridge which is just under $4k. I appreciate the set it and forget it nature. There are other options from manufacturers such as VPI that allow more adjustments and tweaking. 

i don’t know what is best, been through many over the years, though certainly haven’t tried them all, and i streaming more these days

but my favorite two tt’s are the oracle delphi (i have a nicely restored v2 with a brilliant origin live arm) and then the well tempered labs amadeus
