    Involvement Level: Expert (understands the inner workings)

    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 at all.

    Cons: Screw connectors are very small, there is no screwdriver, and the cable is also difficult

    Other: Totally recommended, not worth anything go riding.

    Involvement Level: Expert (understands the inner workings)

    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.

    Other: Very nice product for DIY projects. I would buy again.

  • good but worse when put on loud

    posted by felixstaessens on 11:06:38 G1T 05/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 when you fix it it will get fairly hot, not when you put brackets to let air through

    Other: good put not perfect

    posted by piotrv on 05:21:12 G12T 10/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 this job very well. I am impressed with what you get for this price

    Cons: tiny connectors, but hey, it is a tiny board! After some fiddling with the speaker cables, it's not a problem

    Other: You won't get any better for this price and size. price/quality ratio is beyond expectations

    Involvement Level: Expert (understands the inner workings)

    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 little or no heat, even if played at high volume for quite some time. -Very convenient board layout. -Gain can be set from lowest to highest by moving one jumper. -On/off pins can easily be connected to a 3-pin switch. -Screw holes in the corners of the pcb, very nice for mounting!

    Cons: -Still haven't figured out how these terminals really work. Anyway, they are a little too small. Not that you need big cables for all the power going trough or anything, but it is basiclly hard to get cables that are small enough!

    Other: Go right ahead and buy it! It is superior to anything I have ever seen for this price! Perfect for DIY, and as a daily amp, really!

  • Great little amps!

    posted by wadeweppler on 10:01:44 G11T 26/11/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 that matter. - No adjustable tone/bass/treble/crossover. Just a simple amp.

    Other: Would buy again for other projects!

  • Great, but with a design flaw

    posted by FrenkiBoy on 09:13:33 G9T 25/09/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 supply) - only usable with own ungrounded supply (wall-wart is OK). Same issue causes popping on connection/disconnection of input cable. Too small connection points.

    Other: Really worth the money, but check if it suits your system (own ungrounded power supply needed) to avoid noise.

  • VMA2015 15W Stereo Audio Amplifier

    posted by logotrikes on 04:47:13 G12T 07/12/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 probably about 5 or 6 wpc of usable watts into 8 ohms, but this is more than enough, certainly for my set-up, to fill my listening room with quite decent sound. Plenty of detail but a bit light in the mid-range. Very pleasant sounding with no obvious vices that I've noticed yet.

    Cons: The board is so small as to make connecting anything but the smallest of speaker wire into the tiny blocks. However I cheated by using 1.6mm brazing rod into the blocks with the amp in an enclosure and then hardwiring those rods to better quality binding posts. Ditto the RCA plugs I added...a perfect solution at little cost.
    A bit hard working on the board owing to it's small size, but doable. It wouldn't put me off buying another.

    Other: Buy one and enjoy $20 worth of outlay...

  • Simple, sounds good, good power

    posted by jcinacio on 14:44:28 G7T 24/07/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 and it works perfectly.

    Cons: No built-in volume control.
    The Cap seems a bit smallish

    Other: If you plan on using the volume control from another source (mp3 player, cell phone, etc) it will just work.
