Best turntable for the buck


I now amazingly find that my analog system has fallen behind my digital system in  SQ and I want to investigate how to improve it. 
Currently I have a heavily modified Rega RP3 turntable, with two power supplies, a new platter, sub-platter and other internal enhancements. My cartridge is the Clearaudio Virtuoso.
Not that it’s bad, but I want to look for  something that will significantly improve the sound of my current setup. 
Will about a 4K investment do that?

Well, I got the Sutherland 20/20  installed on my system.  The good news is that it sounds fantastic right out of the box!  Night and day difference. Probably a much better choice than getting a new turntable,

 Yes, I think I’m going to be listening to a lot more records.

It is quite pleasing to see your choice made has been able to create such a positive impression, I know how significant a impact a well chosen Phonostage can have.

I would recluse now , enjoy the Honeymoon Period and get a good few hundred hours on the Phon' and Cart'.

You have made what might be a very good next course of action known in the quotes above, amalgamate the used words from above,

 "Yes, I think I’m going to be listening to a lot more records, Night and Day".     

OP,

Yes, the impact of a great phono stage is incredible. I remember purchasing a $200 “A Recommended Component” Phonostage from Stereophile nearly 40 years ago. It sounded just terrible, I mean really bad. That started my upgrading that only slowed when I bought an Audio Research PH2… but upgraded as fast as I could afford it. The impact only slowed when I bought an $8K (I think) Audio Research PH8… but I continued upgrading and getting benefited to my current ARC REF 3. Really important!

The only downside is that the preamp reveals the flaws in bad records as much as it enhances the quality in good sounding records.
The other issue I’m having (not really a problem but a concern) is the difference in texture between the records and digital sources. Digital sources are more finely etched with better sound staging whereas analog rounds off the edges a bit, but still has wonderful detail.
‘That might be a cartridge issue.
