    Great Product

    Overall: 5 out of 5

    Very good sound, no distortion even when cranked to the max.

    The unit has ample volume. I'm currently running off batteries.

    Great buy, I'm satisfied.

    Outstanding!! This lil' amp is very clear,and quite loud. Hook it up to good speakers,an you will be surprised at it's performance.If you have a spare ac adapter it will play even louder![the adapter should be at least 2.0 amps] I'm using batteries,until they are spent,then I will use the adapter.Very pleased with this amp.

    Great Unit

    Overall: 4.5 out of 5

    Great little amp. I have used a few of these Tripath amps in the past and am very impressed with them. I used to be a sound engineer before I switch to RF design. I have designed and built three radio stations an many recording studios so I can be a tad fussy but I am also frugal. These tripath amps are great if you run them off a good linear power supply with proper voltage and current. Switcher power supplies will work ok but not as well. This unit is cased a little flimsy but it will work great if you do not plan on moving it around too much. I would not hesitate to recommend these or use them. The little kid in me says they are just darn fun to play with. The big boy in me just says "Yes"! MCM sells some great linear power supplies for CB's and HAM radio that are reasonably priced and perform well. These are what I use. Adjust them to 13.8-14.4 VDC. This will give you the best performance. These units do not even get warm.

    Great little amp

    Overall: 5 out of 5

    I have been looking for a low cost, clean specs, good sounding amp for a number of small sound applications. This fits the bill in every regard. Very quiet and low distortion as long as it is not driven too hard. Don't care about the batteries, give me an internal AC power supply!

    good amp

    Overall: 4.5 out of 5

    This is what I was looking for to use with set of 5x7,10w, 8 ohm speakers that I put in a case, to use with Mp3 player when sitting next to the bonfire. Now I don't have to run extension cords out to power a set of computer speakers, that I was using. Would be nice if it had a simple tone control.

    Recently installed a 42" LCD television on wall of a local cafeteria and needed something to drive four ceiling speakers. This amp fit the bill perfectly. It was small enough to double-face-tape to the mount, prior to hanging the TV. It is being driven from the headphone output and sounds great, providing plenty of volume when needed, This is the perfect "utility amplifier" with many many uses. I highly recommend.
