    Best bang for the buck

    Overall: 4.5 out of 5

    The amp that runs the speakers for a very large patio at a restaurant & nightclub burned out. It had to play large speakers loud enough for a late night young weekend crowd, plus all the loud bangs, booms, & crashes of our outdoor movie night twice a week. I had the boss buy this amp. It runs in the main sound/DJ booth with other amps for the main room & dance floor. So the sound booth gets very hot when everything is running. There's no AC vents in the booth. Although we didn't need anything as powerful for the patio as for the dance floor, it still had to be pretty powerful. We just went through a heat wave here. I don't remember the sound booth ever being hotter. This amp ran perfectly pushed to the max throughout it all. Yes, the amp got hot in there but not dangerously so where we felt it might fry. We could buy 3 or 4 of these for the cost of the old amp that fried.

    Whole House Audio for HAL Ultra Home Automation (HomeAutomatedliving.Com)

    Overall: 5 out of 5

    We moved to a newer home last fall and luckily it was prewired for ten ceiling speakers. We installed a total of 14 six+ inch ceiling speakers and then tied as stereo outputs to this amplifier which remarkable is only at 1/4 power when on 24/7. The heat output is minimal and not like similar brands we have tried over the years. This is a professional type rack mounted unit. (like in Trip-Lite Rack)

    We tied our home automation and alarm system into this amplifier so we can monitor any window/door open/close and its announced over the speakers along with other HAL features.

    The sale price is almost worth buying a backup unit!!

    Really great amplifier with no hiss or hum!! Duane - retired space system engineer

    good power amplifier

    Overall: 4 out of 5

    the pla900 power amplifier is vary well constructed, this two channel amplifier has a large power transformer....his unit uses unbalanced connections and i would say it puts out 150 to 250 watts per channel under 8ohms... and the weight of this amplifier is about 33 lbs... a few draw backs, it would be better if this amplifier had rear ear mounts, and true balanced xlr inputs and outputs, plus binding post for speakers for direct wiring... as stated, this amplifier is worth the money for value and quality...... it would be nice if steller labs comes out with a much larger power amplifier in the future that puts out at least 500 watts or larger under 8 ohms....
