SRM 700 S

The SRM-700S is an electrostatic headphone driver utilizing a fully discrete dual FET. The output of the J-FET and the large current emitter follower circuit are low noise. Accurate music reproduction is realized without missing any fine details.

New semiconductor driver with J-FET in the amplification stage. The custom-made, low-noise dual FET is low-noise.

The power transistor array with effective heat dissipation through a large-sized heat sink

Hand selected matching FET

High-definition film capacitors are used

Bypass volume control switch

Volume control is EMI shielded

Switchable RCA and XLR inputs. RCA parallel out.

The newly developed large-sized aluminum insulator combined with new vibration-proof material and high frictional coefficient (grip power) have been employed.
