Almost no use, this is the top of the line Stax headphone amplifier in the original double box The SRM-T8000 is STAX new designed top-of-the-line driver unit. For the first time in STAX driver unit history, the large-sized toroidal transformer and non-magnetic aluminum chassis have been adopted for unclouded clear tone quality! A newly developed large-sized aluminum insulator, combined with new material of high isolation efficiency and grip power, make this flagship designed SRM-T8000 a top performer. Features: • The full-balanced transmission of hybrid amplifier configuration with 6922 dual triode tube of established reputation for the first stage and class-A operating semiconductor at output stage realized ultra low-noise, accurate and rich musical expression. • The vacuum tube of the first stage was mounted on the independent board in order to shut out vibration and external noise. Further, noise has been totally eliminated by vibration-proofing damper and vacuum tube shield cover which are used also for a hard disk etc. • The large-sized toroidal transformer - for the first time in STAX driver unit history - as well as non-magnetic aluminum chassis has been adopted for unclouded clear tone quality. • Four pairs of inputs are equipped. (Notes: LINE4 is an optional slot for future purpose. As for now, release is not yet determined.) • The SRM-T8000 features the EXTERNAL (BYPASS) function which passes the volume controller of the unit and enables volume control through external equipments. • The newly developed large-sized aluminum insulator, combined with new material of high isolation efficiency and grip power, has been employed.
