Stax has an­nounced a new hy­brid head­phone am­pli­fier which uses a 6922 twin-tri­ode in the pre-am­pli­fier sec­tion and solid-state Class-A cir­cuitry in the power out­put stage. The Stax SRM-T8000 has the twin tri­odes mounted on a sep­a­rate PCB that’s vi­bra­tionally iso­lated and shielded from the chas­sis to pre­vent ex­ter­nal vi­bra­tions and noise from af­fect­ing the per­for­mance of the valve through mi­cro­phon­ics.

The SRM-T8000 uses a large, high-cur­rent toroidal trans­former in its power sup­ply and has a by­pass func­tion that re­moves the vol­ume con­trol from the cir­cuit, so you can in­stead ad­just vol­ume us­ing an ex­ter­nal de­vice. It also has a pass-through in­put (in­put 1 of the two line-level un­bal­anced RCA in­puts) so you can route a sig­nal through to other com­po­nents. In ad­di­tion to the two un­bal­anced in­puts, there’s a bal­anced in­put, via XLR.

Stax rates the fre­quency re­sponse of the SRM-T8000 as 1Hz to 115kHz, with THD of less than 0.01%. With a sen­si­tiv­ity of 100mV it pro­vides gain of 60dB. It mea­sures 320×103×395mm (WHD) and weighs 7.3kg. For more in­for­ma­tion, con­tact Au­dio Mar­ket­ing on (02) 9882 3877 or at­diomar­ket­
