Turntable upgrade, tweaks, or stay put?

Not sure how similar the kW500's built in phono stage is compared to the stand-alone kW phono stage. I have the stand-alone and it is a fabulous phono stage. A real keeper in my book, preferred it claerly over the SimAudio 5.3LP with optional external power supply and the Avid Pulsus (which I also preferred over the SimAudio). Like many pieces of audio gear, think the kW really sonically benefits from its burly power supply.

At the price of the VPI Classic, you have a number of nice turntable options. Are you anywhere that you would be able to audition tables? Rega, Well Tempered Amadeus, Townshend Rock (my current table, and a bit pricier) are all great options. Avid and Basis also have tables in this range.

Thanks for the suggestions. I'm not sure if those phono stages are the same, but the integrated sounds great. It may be very similar. I have never had the opportunity to compare.

Separates tend to have some advantages, like isolation and dedicated power supplies. But if the circuit in your kW intergrated is similar to the stand alone then you may already have a very good phono stage on your hands. Best to try to audition another quality phono stage and see how the kW stands up to it. A number of online retailers with good return policies if there isn't a dealer nearby with something that interests you. Music Direct has the Avid line. It was Chris there who put me onto what a great phono stage that Pulsus is. And he has heard a lot.

Ok, so I am thinking of going all in with the scoutmaster. Is the SDS a worthwhile upgrade? Thanks for your opinions!

Is the SDS a worthwhile upgrade

Absolutely, some would consider it a must.
