Fire and Water
I first bought this album in the 1970s as a college student and played both sides endlessly. Through the years, I've purchased the album many times including SHM and SHM-Platinum versions as well as SACD.
The UHQCD version delivers the best soundstage yet. The first track didn't really come across all that differently, but by the second, I actually looked up at the speakers as I was somewhat startled by the bass, drums, and lead guitar. I'm not sure if this is a chicken or egg thing as I have a top of the line OPPO player and new speaker cables that cost more than some people's speakers. But when I played my old SHM CD copy, my listening experience was confirmed.
This is an audiophile's format for sure.
