Don't let the compact size fool you Dayton Audio's DTA-1 mini amplifier is a serious piece of audio gear. A proprietary Class-T amplifier chip enables the DTA-1 to be 88% efficient while still producing pristine, high-resolution output. This makes the DTA-1 T-Amp an obvious choice for powering high efficiency single driver speakers. Up to 15 watts of power per channel is on tap to drive desktop and bookshelf speakers, for the ultimate portable hi-fi setup at home or in your office. The Dayton Audio DTA-1 T-Amp can run off of 8 AA batteries for total portability, or the included switching power supply (with quick-release US and European style plugs) for stationary use. A rear mounted 3.5 mm stereo (1/8) audio input is provided. The amplifier also includes a 6 long, coiled male-to-male 3.5 mm cable for making connections to iPods, MP3 players, PCs, and portable CD or DVD players. Spring-loaded push terminals are incorporated for quick speaker wire termination. Intelligent short-circuit and over-temperature protection ensure amplifier longevity. The Dayton Audio DTA-1 is the perfect replacement for the now unavailable Sonic Impact 5066 NIB class T amplifier. Dayton Audio has taken the technology developed for the Sonic Impact 5066 and perfected it in this hand-held digital amplifier. Specifications: ; Power output: 2 x 15 watts RMS (into 4 ohms @ 10% THD), 2 x 10 watts RMS (into 4 ohms @ 0.1% THD) ; Efficiency: Greater than 88% ; Dynamic range: 102 dB ; Dimensions: 2 H x 6-1/8 W x 3-3/4 D

My family has an old sony receiver for the family room. Every powered channel (not the subwoofer output) stopped working. I opened it up and everything seemed fine except for the fuses between the main laminated core transformer and the main bridge rectifier. I replaced the fuses with the same type and rating but they kept blowing up. I think the bridge rectifier is broken and is somehow creating a short circuit. I don't know for sure because I haven't tried replacing it yet. Because of this, I had the opportunity to bring our family room's speakers (a pair of Niles CTRBx center channel speakers)in our computer room for near-field, on-axis listening. They're huge on desktop. Both of my parents (I am a highschooler at the time of this review.), immediately complained but when my dad heard one of the best speakers in the house near-field he stopped. My mom still complains but hey, my dad is still on my side. Once we get an amp(either the smsl sa50 or a refurb receiver from accessories4less) for the family room its over. I'll just save up for a used niles ctrbx (We have 3 of them. To make two stereo sets i only need one more. That way, I know i won't need to buy a separate subwoofer when i get a job.
Actual Review for the Dayton DTA-1 (Sonic T-amp clone):
I was extremely surprised how small and light it is. This is my first t-amp. Its so cute. The overall build quality is good. Unlike most t-amps, it has a 3.5m trs input instead of a set of rca jacks. The spring clips on the back are annoying because they don't take low gauge (thick) wire. The on and off mechanism seems like it will get loose over time but i can't say for sure because I've only owned this for a few weeks. Installing the batteries in the compartment is a pain. The blue LED needs to be covered with tape or some black sharpie. This along with the sub-bass roll off took off a star.
I don't have any equipment to measure it but the datasheet for the IC should be a good estimate. At 8 ohms, it should output around 5 clean watts per channel. This is more than enough for near-field and enough to fill small-medium sized rooms as long as your speakers aren't insanely insensitive (under 86db at 1 meter with one watt). You'll probably have trouble with larger rooms unless your speakers have an insanely high sensitivity over 96db.
If you'd like a rough estimate of how loud it will get in your listening environment, definitely check out the link below.
With battery power, it can get pretty loud (the speakers i used to test this amp have a sensitivity of 90db) but that will drop along with the batteries' voltage. I don't have any hard numbers but reduced output is guaranteed because its a 12vdc 2 amp wall-wart vs 8 aa batteries.
It doesn't have an absolutely silent turn on but it does have some kind of initial pop protection. Its certainly better than nothing *Cough* Lepai *Cough* *Cough*
There is a bit of a sub bass roll off starting at around 60hz-70hz compared to the av receiver we were using. Input decoupling and power supply decoupling capacitor upgrades are pretty popular for this amp.
Aside from that, I have no complaints, even when comparing it with full size av receivers. Its pretty much neutral as far as i can tell. The soundstage and imaging is very good with anime and music. If the sub-bass roll off bothers you, try out an eq. EqualizerAPO is a great system-wide for windows. You have to edit a .txt file and follow a certain format to use it properly.
Capriccio and onkyo hf player are good ones for IOS. I'm sure you can find something on the android play store.
My top 10 anime:
2. Code Geass
3. Angel Beats
5. No Game No Life (Beware of Ecchi... If you don't know what "ecchi" is, you'll find out within the first 30 seconds of the anime)
6. The Devil is a Part Timer
7. Full Metal Alchemist Brotherhood
8. Death Note/AOT
9. Sakurasou no pet na kanojo
Should you binge on all of them this summer?
Anime is not a one size fits all type thing. Go talk to someone who knows you well and watches a lot of anime. I'm sure they'll be glad to help you as long as you don't mention "One Piece", "Fairy Tail", "Bleach" "Naruto", etc...
I got one of these, hooked it up, and was receiving a ton of distortion on the left channel. I moved the speakers around to verify it wasn't a problem with any of the other components, and was able to confirm it was an issue with the amp. I requested a replacement from Amazon, figuring "well, there's no way I could get TWO that don't work, right?"
I literally just got the replacement unit. Less than an hour ago. I hooked it up, and - yay! - no distortion. It was sounding good! I was just about to hook up a different audio source when the audio cut out. Just for a moment, at first. I listened for a few more seconds and it cut out again. Less than thirty seconds later, there was no audio at all. The unit completely died.
I just packaged it back up. I'm about to send both back, and request a refund this time.
Do yourselves a favor, and stay away from this mess. As other reviews have touched on, the build quality seems to be absolutely abysmal. Even if you get a unit that doesn't have any immediate defects, can you really trust that it won't break a week from now? A month from now?
Only 3.5mm input is a limit, but than not really if you are using something like an iPod or iPhone as a source. Speaker terminals are spring clip type and won't take greater than maybe 14ga wire. I doubt 12 will work. But THAT'S not a problem either, since for short runs at this very low power, how could that matter much?
I have not tested with batteries so I don't know if Lithium or NiMh will work. Alkaline is recommended. I'm also curious if something like a 12v GelCell would work? Recharge periodically and you are good to go. I have NOT heard any noise generated by the wall wart, but wonder if it's output is enough to drive the amp to max power.
