Sounded better at Starbucks than my home?

I heard some new music with old, familiar voices at Starbucks, looked at the CD, saw two great, well-respected artists, and one of the best producers. I found a vinyl copy, and placed on my turntable, expecting a great experience. I was very disappointed in the quality of the sound-no highs, nothing dynamic. So, I played some of the records that I purchased in the 70's by the same artists, and those still sounded great. So, my question is, how can professionals with those reputations release such poor quality recording, especially to the vinyl community? And the next obvious question, how do I learn what modern vinyl is worth the premium $30 price, double the CD?
