FAQ:
Q: What do you need to know about the SMSL sa-50?
A: This unit received over 50hrs of burn-in, no differences were noted. The SA-50 comes in a simple blue and yellow card box, the amp is held tightly in place in foam, and the power supply is also well secured. The box is nothing fancy or special, but serves it purpose of protecting the amp during transit.
Q: How much does a sa50 Polk amplifier cost?
A: Well this has been fun, thumbs up to the cheapest system that will impress most people using the SA50 to push the mains! I hear BB discounts the Polks about this time of year to $50 (Black Friday), so you might spend as little as $180 on a 2.1 with a real 100 watts and Polk sound.
Q: Which is better the Lepai or the sa50?
A: The SA50 should have the notoriety that’s bestowed on the Lepai. It’s four times the power and higher quality. I’m an audio engineer who has had time off from mixing and mastering in studios on two continents and so playing with cheap digital amps is my entertainment.
