Kenwood R SA7

The Kenwood R SA7 is a compact and high-quality mid-size form factor from the mid-90s. What makes this amplifier unique is the switchable output stage between Class A and Class AB operation. In pure Class A mode it delivers an exceptionally warm, detailed, and audiophile sound for critical listening at lower volume. With its chic champagne-colored front panel, FM tuner with RDS, and convenient subwoofer output, this is an advanced and beloved classic for compact hi-fi setups.

Total Harmonic Distortion (THD): 0.02% (1 kHz, 10W, 6 Ohms)
Frequency Response: 20 Hz – 100 kHz (+0 dB, -3 dB)
