All tapes are recorded on a specially modified Revox B215 tape transport in a full-track configuration, using BASF Reference Master II or TDK SM-X Professional cassettes and a special Full-Track amorphous recording head from JRF Magnetics. Alignment tapes from BASF, STL, Teac, ABEX and Sony are used as primary references.

Each tape has a unique serial number and fully checked in both directions on two reference playback decks. Playback results are recorded on a computer for a full analysis and verification.

Custom alignment tapes can be made on order.
