Hello-

I'm looking to add an entry level amp to my HT setup. I would like to get something to drive the RTi10s that I am currently driving with my Sony STR-DA5000ES receiver. I was looking at this amp by Audiosource:

I was also looking on ebay for some Adcom amps as well. I would like to get an amp with a 12V trigger so that I can integrate it into my HT cleanly (read: Wife doesn't have to push any buttons on HT gear to get the TV on)

Thanks.
David

    I have a Rotel 1075 5-channel amp. If you are interested in this amp, let me know.

    I've been using an Audiosource amp (Ampthree, maybe) in my HT set up for years. 150 wpc, solid, does have some nice funtionality to it. Never had any reliability issues with it. Does have some hum to it no matter where I've had it set up, tried cheater plugs, etc.

    Do you have a price range in mind? I take it your ok with a used amp. Does your receiver have a switched outlet on the rear of it? If so, it would relieve you from needing an amp with a 12v trigger. Or you could just leave the amp on all the time, which I've done in the past as well.

    Also, just a 2 channel amp? What are you using the system for mostly? 50/50 music/HT, etc.

    Good impression.

    To what are you referring when you say it's limited to 120w or so?

    Most switched outlets (if not all) on the back of recievers/pre-amps are limited to 100w - 150w output current. I have yet to see a power amp that draws so little current.

    It will eventually burn up the power supply in the reciever.

    The limit the manufacturer usually states that a rear switched outlet on a receiver would have in total load. Sometimes it can even be as low as 50w. Not nearly enough to power an amplifier.

    Gotcha, thanks. Just checked the online manual, damned if my receiver doesn't max out at 50w on the switched outlet.

    If we could edit, I'd take that advice out of my post, but since we can't....

    Outlaw Monoblocks would be a great choice as well, and drive those 10s with no probs. Worth a look, www.outlawaudio.com and check out the M2200.

    Thanks for all of the replies. One of the questions asked about budget. I am looking at something less that $500. Usage would be 80% HT and 20% music. I share a few common walls, so I don't want to get too loud. As you can see from my sig, I have a 5-1 setup. I was initially looking to use my receiver to drive the center and rear channels, and use the new (or new to me) amp to drive the fronts.

    I have never used an external amp, so those of you with them, is there a big difference from using a receiver with a built in amp and using an external amp?

    Thanks for the info on plugging the amp into the receiver. I do have one of the switched ports that people here referred to, but I don't use it. I don't want to tax the receiver too much, and the switched port can't handle that much anyway.

    Thanks again for all of the info.

    I had a sony 7100es on my 12s, I then added the Outlaw M2200s to drive them and it made a huge improvement. Later on I added another Outlaw for the center and allowed the Sony to handle the rears and side surrounds.

    Not likely as it doesn't draw current from the units power supply at all.It can however exceed the current rating of the internal fuses ,switch contacts ,wiring etc.
