Digitally recorded vinyl vs streaming

It’s very possible that albums from the 90s were recorded to 2" analogue tape. Then transferred to digital for post production; many ADD albums from the 90s.

No matter what the process, there were many good quality albums from that era.

In my experience, where I have both the digital and digitally engineered LP’s to compare, I almost always prefer the LP’s recorded digitally vs the digital file.

“I have a McIntosh tube amp, and a VPI table.  For Streaming I have a Bluesound Vault.”
Based on your preference for Vinyl and given your investment in digital, stick with spinning Vinyl. 

I really like the Blu app, easy to use and I can stream Tidal.  It also holds my entire CD collection.  Having said that, I have considered upgrading.  I listened to a Rose rs150 ($5000), but it didn't sound 4 times better than the Bluesound Vault.

It is about the value you place on better sound quality. I find each time you double (or better) the investment (a well researched and chosen upgrade), I get a “wow… that sounds better” to me. That makes me very satisfied and happy.  So, on all my components, I have gone from ~$500 -> $1,000 -> $2K -> $5K -> $10K -> $20K over the last fifty years. Each has been incredibly satisfying and worthwhile. I could not be happier. Lots of people would have stopped at the first purchase and called everyone that went further a fool. 
 

So, it is what makes you happy. I told you what makes me happy. If the market does well, maybe I have time to go to the next level. But if not I enjoy my system for three hours a day and am happy I did it.
