Krell Theater 7 XD
DESCRIPTION
The Theater 7 XD amplifier design uses Krell Current Mode technology—fully differential and discrete in the critical gain stages. This results in a highly linear and extended frequency response, well beyond the range of hearing, for smooth effortless highs and tight high impact bass.
