The Stellar Strata MK2 is an integrated amplifier with a built-in DAC and phono stage from PS Audio. This model combines amplification, digital conversion and phono equalisation within a single, relatively compact chassis.
Position in line
It is one of the more full-featured designs in PS Audio's integrated amplifier hierarchy.
Key specs that matter
Rated output is 100 W into 8 ohms, rising to 150 W into 4 ohms. The built-in phono stage covers MM at 47 kOhm and MC at 100 ohms. Distortion is under 0.02%. Damping factor is 29, a modest figure. At 559 x 203 x 43 mm and 11.4 kg it is a low-profile, wide chassis, unlike a conventional boxy integrated amplifier.
Pairing
One balanced and two single-ended inputs plus phono cover a modest source lineup without needing external switching.
Alternatives
The Sprout100 sits below this model in PS Audio's range as a more compact, simpler alternative.
