Good Sub $100 Amplifier?

post #1 of 11
Thread Starter 
My DTA-100a is toast and I am looking for a new amplifier. I would try to fix it myself but I have no idea how to detect what is wrong with it. Even if I could find out what is wrong with it I have only very minimal soldering experience that I learned in high school auto class. There's no way I could solder things to and from a PCB.

My current setup is a pair of Dayton B652s which has the specs of: 40 watts RMS @ 4 ohms. I'm looking for a good 2 channel amplifier that can support that kind of power. I'm also looking for a good RMA policy in my future amp in case it goes south too.

I've already ruled out Lepai since their packaging is so inconsistent that they appear to be a fly by night operation and Pyle for their terrible RMA policy.

Thank you,
Matt

That looks like a good choice. Under $100 on TigerDirect, supports the wattage required. There aren't many reviews out there on it but I did see some forum posts on it when I googled it. Thanks for the heads up.

No problem. One thing to note, is that you should use input 2 as the primary. Input 1 has an auto off power saving feature that you may not want to use.

Haha I actually saw that while looking for information on it. Thanks for the heads up.

Does anyone else have any recommended amps or any opinions on the AudioSource AMP-100?

Do you mind a little DIY stuff?

http://www.firstwatt.com/pdf/art_f5_turbo.pdf

A little back round, First Watt is owned/operated by Nelson Pass, the founder of Pass Labs which builds high end amplifiers that cost THOUSANDS and THOUSANDS of dollars.

He does some work and makes the plans available to the DIY community as a hobby as he gets some intellectual benefit from it. If you want to find more about this F5 amplifier then you can go to diyaudio.com and do a search.

I do not know how much it costs in total to build but I the PCB will cost you about 60 and then as long as you dont get the exotic caps/resistors etc you could get done with it for a really cheap price. I dont know the cost of heatsinks though...

I'd be all for it but it looks like it is far beyond my electronics skill level. The furthest I've ventured into electronics is basically soldering wires together. I don't have the soldering experience and electrical know how to under take that kind of task. I couldn't even fully read the diagrams it showed.

I'll definitely keep this idea around for later when I have more money to spare and hopefully more electrical knowledge. From what I hear some of the best audio systems are DIY. I'd love to get into the whole hi-fi scene.

Thank you for your post, it was very eye opening. thumb.gif

Oddly enough the Dayton Audio Sub-80 is a fantastic little sub.
As for the amp, Im using a Denon Receiver and haven kept up on amps in a few years.

I can't speak for the Sub-80 but the Sub-120 I have is the best sounding sub I've ever had the pleasure of listening to. The pair of B652s I have are also by far the best sub $50 speakers I have ever listened to. Nothing even comes close to them in that price range. It's a shame that Dayton doesn't make their amplifiers as good as their speakers. Their speakers are exceptional, from my experience and the many reviews online their amplifiers aren't reliable. I'll continue to buy their speakers but I won't be buying any more of their amplifiers.

I was using a handed down old Denon Receiver before it failed and I got the Dayton amp. It lasted about a year in service to me before it failed. One day it started to continuously increase the volume. Before it failed it was a good receiver.

A little back round, First Watt is owned/operated by Nelson Pass, the founder of Pass Labs which builds high end amplifiers that cost THOUSANDS and THOUSANDS of dollars.
He does some work and makes the plans available to the DIY community as a hobby as he gets some intellectual benefit from it. If you want to find more about this F5 amplifier then you can go to diyaudio.com and do a search.
I do not know how much it costs in total to build but I the PCB will cost you about 60 and then as long as you dont get the exotic caps/resistors etc you could get done with it for a really cheap price. I dont know the cost of heatsinks though...

did you read that he barely knows how to solder and wants a warranty? even tho a gain clone would of been a better recommendation.

i would just get the amp d-block said. easy and should do what you need.
