The SRM-1 MK-2 family consists of three models, the SRM-1 MK-2 which supports two normal bias outputs and the SRM-1 MK-2 Professional which supports one normal bias and one pro-bias output. Both were introduced in 1982. Then in 1989, Stax introduced the final model in this family, the SRM-1 MK-2 P.P. Where both output sockets are pro bias, Stax used a balanced circuit design for the SRM-1 MK-2 family, which depends on good matching between the two halves of the amplifier to cancel out even order harmonic distortion. The unit on sale here is in overall excellent condition. This model supports any of the mains voltages 100V-117V-220V-240V AC. We are Gannons Antiques and Art in Fort Myers, Florida.

STAX SRM-1 MK-2 driver unit, with two Normal bias earspeaker sockets, audio pass-thru, and multi-shift adjuster for (mains) input voltage. Made in Japan.Can be modded to a Pro bias headphone socket, if you have the soldering skills to do such.

Stax SRM1 Mk2 Professional electrostatic headphone amplifier.Normal and Professional bias output. The unit is in very good condition with the odd light mark here and there.Fully functional.

STAX SRM1/mk2 pro amplifier. Some small marks on paint and faceplate (see photos) but really in excellent condition given its age (these were manufactured from 1982 until 1995). I had this one refurbished as one channel didnt work when I bought it. Capacitors were replaced with better ones, along with some other bits and pieces. It now works flawlessly, but has seen little use since refurbishment. This has sat on a shelf unused for the last few years after I upgraded to a STAX T1 amp. I kept it as a spare but have now upgraded again. I dont need 3 STAX amps! This particular version is sometimes called the swiss army knife of STAX headphone amps, because the input voltage is switchable (100 / 117 / 220 / 240v) and it offers both normal and pro bias outputs. As a result it can be used anywhere in the world, and power any STAX headphone - (although it would be underpowered for the SR-007 or SR-009.) That doesnt mean it isnt loud enough to destroy your hearing in minutes at maximum volume with compatible headphones! NB: this will NOT work with dynamic headphones. It is an electrostatic amplifier, for electrostatic headphones (ie: STAX) I also have a very nice pair of STAX headphones (SR-404 signatures) listed and would be negotiable on price to combine the two.
