Mini Amp on Revain in 2021 That Really Works? As?!

I can't believe I finally found a working mini amp, but the broken clock seems to go twice a day. This is the cheapest mini amp I've bought from Revain that really works, making it a top 3 mini amp on Revain.

Pros
  • Dope 🔥
Cons
  • Miscellaneous Miscellaneous

A very good surprise!

I was looking for a small amplifier for a CD/DVD player. I was pleasantly surprised by the power this little thing exudes! I temporarily hooked up my 2 Polk Audio speakers to this and was blown away by the sound quality! This is a small but powerful amp and I'm glad I bought it.

Pros
  • The best in its niche
Cons
  • Weak kit

Good compact device for home audio

Nice compact power amplifier. It has two volume controls for adjusting different sets of speakers. This is more convenient than using the speaker selector and setting all speakers to the same level. It has enough power to drive my 6 outdoor speakers, some of which are over 100 feet away. Loud enough for my taste but not boomy. Great little unit!

Pros
  • Ideal for outdoor activities
Cons
  • Some little things

It works. Bought to power a subwoofer.

Had to add another speaker to compete with the 5.1 setup (8 speakers total). I love that the included power adapter solved the problem instead of finding a 5.5 x 2.5mm tip in my pile of old computer chargers etc. For about $25 you can get an $8-$25 power supply and 2.1 amp with both RCA connectors. and mini inputs. There is a small blue woofer alarm that turns on when the woofer hits.

Pros
  • Excellent overall performance
Cons
  • Protection

The amp is compact and does its job well.

After all, what you pay for is what you get. I have an old SONY two speaker system (early 2000's) and I tried different bass and treble levels to adjust the volume and the output was really smooth (no voice breaks). Its 20 watts per speaker and the sound is pretty good. Someone who is really on a budget and doesn't want to spend too much money can definitely grab this device. Another beauty of this product is that it comes with an adapter. I highly recommend this product.

Pros
  • Decent performance
Cons
  • I vaguely remember

Watch out for sharp edges

The fit and finish of the device make it look cheap which is a shame as it's really decent for the money. If you play around with it a lot, you can use sandpaper or sandpaper to go over all the edges. It's not high-quality sound, but it's decent for a small, less-powered amp. I use it as a subwoofer amp to drive a Dayton transducer for vibroacoustic therapy. That's enough to drive the converter as far as I'd like, and having separate volume controls for the subwoofer and regular outputs is…

Pros
  • Great price
Cons
  • Big and bulky
