The SA-20 is one of the best examples of how a well executed tube/solid state hybrid power amp can sound this good. At 8 ohms, the SA-20 is good for 220W and 420W in 4 ohms. When switched to operate as a monoblocks (internally), the power rating explodes to 600W per channel! That is an amazing amount of power for something that costs this little and doesn’t pack the associated weight of a 600W amplifier. Sonically, it exhibits the solid tight grunt of a solid state amp but tinged with a bit of tube warmth. Neither overpowers the other but instead found a nice balance that showed through the music.
Cosmetically, the amp looks really good. Some minor scuff marks here and there but nothing major. Amp will be securely packed for safe shipping.
