This is the shelf you keep separate from the rest of the collection—the one you pull out when the system's warmed up and you've actually got time to sit with it. Mobile Fidelity half-speed masters, Definitive Sound Series (DSS) One-Steps pressed from a lacquer cut straight off the master tape with no intermediate stampers, and hybrid SACDs that'll play on any CD deck but open up something else entirely on an SACD-capable rig. No shortcuts in the chain — that's the whole point of this stuff.
If you're chasing a specific pressing, this is where the good ones land as we get them. Looking for the everyday spins instead? Head over to Vinyl & CDs for the full run, or check Grateful Dead CDs & DVDs for the Dead's catalog on disc.
