The POWERa STEREO is a two-channel power amplifier from Karan Acoustics, sharing chassis dimensions with the POWERa MONO while offering somewhat more modest per-channel output across two channels. The POWERa STEREO brings Karan's most accomplished current engineering to two-channel power amplification.
Key specs that matter
Input sensitivity is 2,000mV, with input impedance at 30k ohms on both connections. Output power is a substantial 2 x 650W into 8 ohms, rising to 2 x 1,100W into 4 ohms - remarkable per-channel figures for a stereo chassis. Gain is 30dBu. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds an exceptional 120dB, with total harmonic distortion plus noise at 0.03% with full global feedback. At 504 x 292 x 603mm and 105kg, the POWERa STEREO shares identical chassis dimensions and weight with the POWERa MONO.
Sound and use context
Expect extraordinary power delivery combined with exceptionally clean measured performance reflecting the substantial 650/1,100W-per-channel output and extraordinary over-120dB signal-to-noise figure, representing Karan's absolute current flagship stereo amplifier engineering ambition.
Pairing
The substantial per-channel output suits demanding, revealing loudspeaker loads directly, and Karan's own PHONOb phono stage shares the brand's coherent engineering philosophy.
Alternatives
Karan's own POWERa MONO offers a monoblock alternative within the same broader amplifier catalogue for buyers wanting dedicated per-channel amplification instead.
