​Atma-Sphere MA-2 Mk2.3 OTL Monoblock Amplifiers (pair at 220w each) - These magnificent output transformerless tube (OTL) amplifiers have set the standard in the industry for many years. With massive power reserve, resolution and transparency, together with an unparalleled ability to recreate highly accurate musical timbre, these amplifiers have been awarded multiple TAS Golden Ear Awards, the Soundstage! 2007 Edge of the Art Award and multiple editors' choice selections.

These amplifiers were fully updated and re-wired by the factory (Ralph Karsten and his team) in 2005 with his new upgraded power supply design, large power supply capacitors, and re-designed circuit topology that Ralph says provided even greater transparency while also being even more gentle on the output tubes. Because of their meticulous point-to-point wiring, Ralph and his team can update these amps to latest-and-greatest status and you will receive a new three-year factory warranty you get when your amps are updated. Contact Ralph for details.

My wife and I are the second owners of these amplifiers and we are only selling them now because we are downsizing and will not have space for the full-size audiophile system we've always enjoyed. See my other listings on AudioMart for more of the gear we are selling.

Note: the photo of the underside of the MA-2 amplifier is from Ralph Karsten, but it accurately reflects the insides of these amplifiers and shows the amazingly meticulous point-to-point wiring.
