What are your go to LP's for evaluating new gear or new tubes?

Check out the October Project album that I listed. It’s amazing in my opinion. Beautiful voices and all different types of instrumentation.

Do you have Qobuz? I know it's on there. 

I don't stream anything..........yet. Never say never but I am very content listening to vinyl and cd's, mostly vinyl. For serious listening, it is vinyl 90% of the time. So...........I'm really looking for what pieces of vinyl stand out as stellar performers in your collection, such that you use them for reference. Jazz is something I never listen to so any jazz albums will mean nothing to me. No intent to offend, I just won't know it. Thanks for any input and to those who already replied.
