    posted by juliov on 03/26/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    This gives very good amplifier output power with very little noise. music is mounted for moving two 8 ohm speakers in series, parallel is excessive because the audio level even the minimum of the source. It is with adjustable gain to a minimum. Not heated a...
    Cons:
    Screw connectors are very small, there is no screwdriver, and the cable is also difficult

    Very powerful for it's size.

    posted by stamatis75 on 02/28/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Small size, can fit nicely in a small project box. Quite powerful, tested it with a 100w roister speaker and run it decently. Voltage used was 18V.
    Cons:
    Only very thin wires can fit connectors, could have been a little larger. Other than that i can't see any drawbacks.

    posted by felixstaessens on 01/05/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    it is low priced and you can use it to make a portable speaker. it is not big and easily placeable the connections are very easy to be connected and are clear. the connection (3,5 mm) is very easy to use and replace if needed
    Cons:
    when you put it on the loudest you get static, this stops when you put it halfway. it feels very breakable when you handle it ...

    Impressive

    posted by piotrv on 12/10/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    You will need a strong and clear INPUT signal, so connecting a smart phone to 100W speakers will give you distortion when turning up the volume even a bit : ) It is an amp after all, so it will not make any sound better or worse. It amplifies and it does t...
    Cons:
    tiny connectors, but hey, it is a tiny board! After some fiddling with the speaker cables, it's not a problem

    Amazing punch almost for free!

    posted by MagnusLysoe on 12/09/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    What a brilliant little amp!: -Plays music at a high volume, even amplifies an iPod to a pretty high volume. -No distortion that I heard, even at very high volume. -The thing is SMALL! The area of it is just bigger than a normal cigarette lighter. -Develops...
    Cons:
    -Still haven't figured out how these terminals really work. Anyway, they are a little too small. Not that you need big cables f...

    Great little amps!

    posted by wadeweppler on 11/26/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    - Worked great as replacement amplifiers in a SoundBridge Radio R1000, with very little modification. Although, a crossover is now needed for the subwoofer. - Inexpensive. - Great audio quality. - Simple to use. - Good build quality at an amazing price.
    Cons:
    - Were a little bigger than I expected, so had to be modified to fit into a smaller space. - No manual at all, or specs for tha...

    Great, but with a design flaw

    posted by FrenkiBoy on 09/25/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Very efficient, loud enough, nice sound.
    Cons:
    Single ended (non-differential) input causes A LOT of noise when the player and amp are both grounded (or have a shared power s...

    VMA2015 15W Stereo Audio Amplifier

    posted by logotrikes on 12/07/2011 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    Very crisp sound, bags of power driving my Fostex full range crossover-less Voight enclosures. It would probably drive all but the most complex speakers, but better with smaller full range or bookshelf speakers I feel owing to the small output. There is pro...
    Cons:
    The board is so small as to make connecting anything but the smallest of speaker wire into the tiny blocks. However I cheated b...

    Simple, sounds good, good power

    posted by jcinacio on 07/24/2011 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    This AMP board is as simple as it gets, but does the job it's meant for. The sound is good (i'm no audiophile but i notice no issues), and 15w is enough power to drive some very reasonable speakers to good levels. I use this with 4ohm, 100w max car speakers...
    Cons:
    No built-in volume control. The Cap seems a bit smallish
