STAX SRM-700T

The STAX SRM-700T is STAX's premier hybrid electrostatic driver, inspired directly by the flagship SRM-T8000, it uses a custom-made low-noise dual FET first stage driving a 6SN7 vacuum tube output stage for a presentation that combines the precision of FET amplification with the tonal warmth and spatial ease of one of the most revered audio tubes ever made.

Type and Technology

Hybrid electrostatic driver, FET input with vacuum tube output. Custom-made low-noise dual FET first stage. 6SN7 double triode output stage, high slew rate, highly transparent vacuum tube with a warm and spacious character. High-definition film capacitors. EMI-shielded volume control. Bypass volume control switch for external preamplifier use. Non-inductive winding resistors with minimal inductance. Newly developed large-sized aluminum insulator with vibration-proof material. RCA and XLR inputs (mutual exclusion). RCA parallel output. 340V RMS maximum output. 60dB gain.

Sound Character

Warm, spacious, and highly transparent, the 6SN7 is a tube that has long been associated with natural, three-dimensional sound reproduction, and its use as the output stage of the SRM-700T brings that character to STAX's Lambda and Omega series without the cost and complexity of the T8000. The result is an electrostatic listening experience with excellent low-level resolution and tonal richness.

Build and Finish

Same chassis as the SRM-700S at 240 x 103 x 393mm and 5.7kg. Volume bypass switch and EMI-shielded volume control shared with the 700S. The 700T can be used in preamplifier bypass mode for system integration.

Best For

SR-009S, SR-L700 MK2, and SR-X9000 owners who want tube character in a high-output driver with the option of preamplifier bypass, particularly those who find the all-FET 700S too analytical in character.
