$ 1,199.95

The Stax SRM-006tS Headphone Amplifier is a valve amplifier for use with the Stax range of electrostatic Earspeakers. It features two 6FQ7/6CG7 dual-triode valves, three inputs (one XLR and two RCAs), and can be used to power one or two sets of Earspeakers.

High-voltage dual triode 6FQ7 / 6CG7 are employed in the output stage of the SRM-006tS. The well-sounding rich mid- and low-range tone covers all genres from vocal to orchestra and enables you to enjoy music over a long period of time.

The balanced input via XLR terminal along with the custom-made double axis 4-gang volume controller enabled a full-balanced operation from input to sound element drive.

High-quality relays are placed close to the input terminal to realize the shortest signal path, and the mutual interference between equipments is eliminated by switching the hot / cold side of the signal simultaneously. 3 lines of inputs are equipped including a XLR terminal. One of the RCA input terminals functions as a parallel out directly providing the incoming signal.
