I have used Tin Pan Alley as a reference track since it was released. I have heard it on hundreds of systems. My current Altec A7 do a fine job. JBL’s that I have had too do a great job in this track. 15” woofers are one of the keys to unlocking the magic as well as horns.
SRV blended a Vibratone with his massive Dumble head into 15" JBL cabinets and Fender Twins. Listen for the Vibratone in the left speaker.
Another classic SRV track is Riviera Paradise. At one point the guitar notes circle the whole room. That’s when you know you’ve got your system dialed.
