Amp advice?

315 Views 4 Replies 3 Participants Last post by  AWalkInThePark
I apologize if there is a thread for this but I have a (hopefully) pretty simple question. I am in the process of setting up the audio for my small apartment I just moved in to. Now I am by no means an audiophile, and really will be using my set up to watch movies, TV, and sports over my HTPC, however I would still like to buy good quality hardware.


I'm going to purchase 2 Polk Monitor 55t speakers as they went on sale today at Newegg, and while they may not be the best speakers, $100 for Polk towers seems like a pretty good deal to me. Because I am planning on using a stereo set up, and my HTPC can do any equilizing, I was going to get an amp and was wondering if you had anysuggestions. I have been looking at a few amps on Amazon as they seem like they would suit my needs. I am leaning toward the Audio source Amp-100, but have also looked at a few of the Pyle mini amps also. Questions are:


1. Will an amp or mini amp similar to the ones I listed above work well for me?


2. Could I get 2 mini amps and bridge them so each speaker has its own amp, and would that be the best option?


Thanks. If there is already a thread open for questions point me to it I'll delete this post.

Unless you're listening to very low level volume, try to get amp with power output in rms of at least 100w so you wont clip them easily ans as well for future matching of your speaker upgrades. Amp is something that doesnt obsolete easily hence its wise to grab some decent amps when you start out this hobby. I would suggest to take at a look at the audiogon for some decent 2nd hand amps at good bargain price. Hope this helps to get started.
Bridging is never the ideal solution for a power amp as most if not all wont be able to handle lower ohms demand (

Could be. One critical parameter is how loud you want to listen.


The speakers you have mentioned above are rated at 150 watts. If you want to play them as loud as they can be reasonably played you might want amplfiiers rated at 150 wpc.

I know of no mini amplifiers that are rated for bridged operation. Generally bridging is the realm of maxi--amplifiers designed for professional use, not mini-amps designed for casual home use.


Bridging can theoretically provide up to 4 times the power, but usually only provides more like twice the power. Trouble is that even 4 times the power is only 6 dB louder before clipping, and it takes much more than that - 10 dB or (coincidentally) 10 times the power to create the perception of "Twice as loud". And that assumes that you are currently running the lower powered amplifier up to just below its clipping point.


In general the cheapest, best way to obtain amplifier power is either amplifiers designed for pro audio use, or surround receivers. An example of an amplifier that is designed for pro use that you could easily use is the Behringer A500 for about $200:




It has a real world 125 wpc, no cooling fans and is well-matched to your speakers and application. It runs about $200 around here.


This is an AV receiver that could also be used:

You can see that due to economies of scale of mass production, you can get quite a bit more for less in an AVR that can easily be configured for 2 channel operation and is also readily expandible for use with a subwoofer.

Thank you for the replies. I considered getting a receiver, but was hoping to save some money by just getting the amp instead. I'm finding that it really isn't much more expensive to go the receiver route. Ideally I would like an audio setup that in 5-10 years could be upgraded to 5.1, as I am perfectly happy using stero for the time being. As for how loud I will be using them, I live in a small apartment building so won't be playing stuff extremely loud. I possibly will purchase a mini amp and a more powerful amp and see which works for me. If the mini amp does the job I will keep it.


Thanks again for the replies I appreciate the feedback.
