Question: Is it okay to leave the power on with no sound going through it?  I'm considering for a rental house where people are confused by a regular amplifier
Document: This is an good small amp with a tremendous amount of power considering how small it is, but if you're shopping for mini amps, you're likely comparing this to the two other big boys in this realm: The Topping TP20 mkII and the Lepai.Note: I'm using these amps with a pair of Polk Monitor 7 speakers.I started with the Lepai, as it's the gateway mini-amp for a lot of people. With a decent power supply (not the one it comes with), it's perfectly fine.
My Polks are fairly efficient, but this amp certainly isn't going to blow the doors off my house.In conclusion.. the SMSL is a great amp with a lot of power in a small, inexpensive package. But if you're searching for the most &#34;accurate&#34; sound quality and don't need the power, the Topping TP20 is probably a better bet.
This is still more than enough power for most people.Overall, I'm very impressed with the sound quality of the SA50. It delivers a ton of power for its small size. Amazing it replaced my old 30lb receiver yet still sounds just as good.
Such a beautiful natural sound from a really small unit. This amp does a better job of pure, unadulterated sound than my larger Sherwood home stereo amplifier. I was pleasantly surprised to find the binding posts could accept bare wire, which was a plus (no banana plugs needed).
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, so you might spend as little as $180 on a 2.1 with a real 100 watts and Polk sound. I had neighbors over for a backyard party and all gushed about how I always have the best sounding music systems and what could I say?
This amp is pretty amazing, considering its price and form factor.I am using it in a ghetto audiophile system from my PC. I have a pair of Acoustic Research AR-18B's & a Polk Audio PSW10 sub, fed  from an ASUS DG PCI sound card, through the optical out, to a Fiio DAC to the SMSL amp. The system is entirely too loud!Sounds very good at all volumes, with no distortion. At. All. It sounds very good to my ear.
I purchased this inexpensive little amplifier to power 2 satellite speakers for a desktop computer system. I've been very impressed. It's well-manufactured. Easy operation. Inputs and Outputs are straightforward. Volume control knob has a precise smooth feel. Able to crank up the volume without any noticeable distortion. Fits nicely on my desk.
ft property. If anything it may be a little bright and a little bass heavy, but that's me being picky coming from decades of attempting to follow the QUAD mantra of 'the closest approach to the original sound'. I'm a neutral nut, don't add or take anything away from sound if you can manage it.
I'm no audiophile or professional, so take this for what it's worth.I use this to power a pair of Energy CB-10s in my bedroom, not sure on the actual dimensions of the room, but somewhere between a broom closet and a master suite, no crazy high ceilings or anything like that. I couldn't be happier. Took it out of the box, plugged it in, ran the cables and then discovered that my tv only had a digital audio out.
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. I know, "Get a life".This amp is about the size of paperback and extremely light, really, an honest 30 watts per that you can fit in your pocket for $70.
Answer: Well I've actually been doing it for the past month with no issues
