            My needs:
            - improve TV sound
            - low cost
            - auto-on

            Met my needs.

            Using modest small KLH speakers.

            There were reported iffy auto-on issues. I had no problems. I was able to configure my TV to use the TV sound control. The auto-on would not work until I raised the TV sound to about 30% of its volume range and had the amp at about 25% of its volume range (9 o'clock position).

            Works great!

                      Great little amp. I was looking for an amp with auto shut down/powe on capability which not many I found had. I am using this with a ceiling mounted video projector in an area with limited space so this was perfect. Build quality is very nice but operation instructions do not match in regards to the light indicators. The unit works fine but the led power button on my unit dose not change color as indicated in the instructions when switching between power on/off.

                        Comments about AudioSource AMP 50 Stereo Power Amplifier:

                        The AMP 50 Stereo by AudioSource is a compact unit that provides very good sound quality. I'm using it as an integrated amp for an electronic organ and feeding it with a delayed signal. For my application this amp has more than enough power to drive two Polk Audio bookshelf speakers and fills the bill at a very reasonable price. This amp has ganged bass and treble controls (bass/treble affects both channels simultaneously) and has a 2nd set of speaker outputs (I don't use them). The only two minor quibbles I have are 1) it uses a rather large external power brick - obviously the amp doesn't have an internal power supply of its own, but using an external power supply can be good actually as it can reduce hum pickup. The other quibble I have is that you can hear a rather loud click when ever you turn off the power using the power button - clearly for an amp this inexpensive internal relays with a delay would have solved that problem but make it more costly. Another issue to be aware of is that the external power unit does not use a 3-prong plug into the AC and uses a typical two-pole plug - so there's no ground pin on the ac cord of the external power unit. Depending on how you use the amp in your application you may experience a ground-hum since the amp itself and its metal case is isolated from ground. There's no way to know if you'll have a ground-loop hum until you actually have the amp in hand and try it in your application. But don't get the idea that you will automatically have a ground-loop hum: I'm just mentioning that since it's a possibility with amps that do not use a grounded AC plug. You can also get a ground-loop hum from amps that DO have a grounded plug - so it's not cast in stone. Otherwise, this is a great little amp that puts out 25 RMS (real watts, not fake, inflated watts) for general audio use. If you're using it on a computer for your left/right speakers it's truly powerful and is probably overkill. B&H's price is very good and you can't go wrong with it.
