Review: Perfect 2.1 amp with ARC (just use your tv remote!) - Exactly what I was looking for and I’m loving it so far. In fact, I even bought a second one. I don’t have space or particular desire for surround sound with my tv. It’s way more effort for marginal benefit. So years ago I bought a couple of pretty good bookshelf speakers, a subwoofer, and a big pioneer receiver. Eventually the receiver died and I didn’t want to buy another receiver with way more features than I needed. I specifically wanted hdmi input with ARC so I can just use my one TV remote to control volume. I also wanted it to handle a 2.1 setup. I was worried this SMSL amp wouldn’t work with my powered subwoofer, but it turns out it does still work if hooked up correctly. The subwoofer must have speaker-level inputs and then the subwoofer’s internal crossover filters the low frequencies. I tried it out and it sounds perfect. So I bought another for my other TV for basically the same reasons: - way cheaper than other receivers - sounds better than my previous, more expensive receiver - very small, well built, looks nice - has exactly the features I want (ARC)
Review: Give it a try! - Great functionality, build quality and compact size. Powers my bookshelf speakers and passive subwoofer really well. Very happy with it. ‘Dropped’ down from an amp much more expensive and I’ve enjoyed the warmer sound signature more than the higher end amp. This is more fun and engaging rather than analytical, great for my office setup.

### ⭐⭐⭐⭐⭐ Give it a try!

Great functionality, build quality and compact size. Powers my bookshelf speakers and passive subwoofer really well.

### ⭐⭐⭐⭐ Pretty Good - subwoofer volume NOT controlled by main volume control.
*by J***Y on January 27, 2025*

Works/Sounds great with a couple quality speakers. Bought this as a set-and-forget amp for a TV. Using the eArc HDMI input, the volume is controlled by the TV remote, so you don't need to add another remote to your collection just for this device. Downgraded to 4 stars for this one issue: changing the main volume doesn't change the subwoofer output volume, so you can't completely mute the amp without adjusting the subwoofer on the amp. I can live with it this way (but my wife complains she can't mute the TV).
