Stax Headphone Amp SRM-T1 Driver Unit for Earspeakers with Vacuum Tube OutputPerfect working condition guaranteed, in exception for top headphone band that is broken.The Stax SRM-T1 is a high-voltage amplifier and bias source for Stax\' electrostatic headphones.The SRM-T1 has two Professional (580 V) and a third Standard (230 V) output, so any Stax earspeaker ever made since 1959, from the original SR-1 to today\'s SR-009, works perfectly. (Stax calls its headphones \"earspeakers.\")The SRM-T1 is an FET-input, tube-output, pure class-A, DC-coupled amplifier. It has no capacitors or transformers in the audio path. It\'s housed in a completely non-magnetic case to ensure no inadvertent magnetic coupling happens. It uses two 6FQ7/6CG7 vacuum tubes in its output stage.It has enough output to deafen us with any of Stax\' headphones, without any distortion.It is fed from any device with 1/4\" RCA jacks, or even directly from iPods and iPads with any 99¢ 3.5mm to RCA cord. If you do your iPod transfers correctly, this and a set of SR-Lambda Professionals sounds indescribably incredible driven directly from an iPod, if you\'ll just listen.This SRM-T1 was Stax\' first tube-output amplifier. It was replaced in 1993 by the SRM-T1S which debuted with the first SR-Omega. The SRM-T1S is the same as ths SRM-T1, except for a switchable input selector.
