Studer A827 M2 — Reference-Grade Playback Transport

Direct Head Output Configuration | ARIA Class-A Mastering Playback System

Price: $30,000 USD

This Studer A827 M2 is offered as a reference-grade analog playback transport, prepared specifically for uncompromised tape reproduction. The machine is clean and configured to bypass the internal Studer playback electronics, allowing the playback head signal to be routed directly to balanced XLR outputs.

Playback Architecture

Direct playback-head output to balanced XLR connectors
Internal Studer playback electronics bypassed
Optimized for use with an external, mastering-grade head preamplifier

ARIA Class-A Mastering Playback Electronics

The system is intended for use with the ARIA Class-A playback electronics, a purpose-designed mastering solution for Studer machines.

Two-channel, playback-only mastering electronics
Engineered by Crane Song and manufactured by ATR Service
Housed in a tabletop chassis with hardwood side panels
Supplied with an outboard DC power supply, supporting 100–240 VAC, 50/60 Hz
Includes low-capacitance tape-head interconnecting cables, internally terminated on the ARIA side for optimal signal integrity

Playback Head Configuration

Supplied with a ¼-inch ARIA playback tape head
Mastering playback head manufactured by Flux Magnetics for ATR Service
Optimized for maximum resolution, low noise, and tonal accuracy

Recording Capability Retained

The machine retains its original erase and record heads
Allows the use of internal Studer electronics or user-supplied electronics for recording, if desired

Why This Is Not a “Stock” Studer

When used with dedicated external Class-A head electronics, the A827 M2 functions as a pure reference transport, analogous to a high-end turntable paired with a world-class phono stage. This architecture exceeds the performance limits of the original Studer playback path and places the system in a significantly higher performance category.

Ideal Applications

Audiophile reference playback systems
Mastering and archival transfer
Critical evaluation of master tapes and safety copies
Studios and collectors seeking maximum playback accuracy and musical realism
