Stellar Strata MK2
The Stellar Strata MK2 is an integrated stereo audio component combining a fully balanced Class A analog preamplifier, full-function DAC, MC/MM phono stage, Class A headphone amplifier, and MOSFET-based 150-watt-per-channel power amplifier. Its digital section provides two I²S, two coaxial, one optical, and one USB input, supporting PCM up to 384 kHz and DSD formats up to DSD256 via I²S. The amplifier provides 100 watts minimum per channel into 8 ohms and 150 watts typical into 4 ohms, with RCA and XLR analog inputs, speaker binding posts, and a ¼-inch headphone output.
