I bought this little amp to power a set of bookshelf speakers for my ipod.While not a powerhouse on wattage, it has plenty of power for efficient speakers (90 db or greater) even in larger rooms. The sound is superb, clarity and depth that I cannot achieve with my larger component system.As long as you're happy with moderate volume levels or smallish listening rooms, it cannot be beat. It's a real bargain.Note: Don't try to use it with speaker wire much larger than 18 AWG, the little inexpensive speaker connectors aren't made for heavy gauge wire.
Highly recommended.P.S. Just bought this amp last month to power the speakers built into the vaulted ceilings of my new home. This little guy sounds great and has no trouble filling the whole first floor of the house with music. Not sure why, but since I purchased this item last month the price has jumped up $10. Used to be a steal at $35, still a good value at $45 I guess.
I used this amp to power two speakers installed on the underside of a roof over a covered deck. It's working great.
And over the years I have owned - and still own - a number of top-quality amplifiers, both integrated and separate.I had a pair of Pinnacle PAS 28 ported (dual ports) 2-way Speakers (Frequency Response: 30-21000 Hz +/- 3 dB; SPL: 92 dB 1 Watt, 1kHz, 1 Meter) which were not being used (speakers do tend to accumulate); they are of excellent quality and I bought this unit to use with them (as you can see they are quite efficient and they offer superb sound quality as well) and also see just how good a T-amp is.Let me state that I am amazed - and you will be too. The speakers are the limiting factor in the overall sound quality obtained; of course a good source is also necessary but I am using mine with an Insignia NS-P4112 Portable CD Player ($19.95 at Best Buy; that's about as cheap as you can get). I also tried the amp with my MP3 player and, as expected, the sound quality was fine.I would really like to try this amplifier with my Klipschorns (which, I believe, are the most efficient speakers ever produced - 105dB @ 1watt/1meter - but the speaker cable I use is too thick to fit in the Dayton DTA-1 Amplifier's connectors and at this stage of my life I am not about to move the 175-pound (each) Klipschorns to change the cable. I have played a number of CDs and SACDs (the CD layer only of course) on this player and through this system - and the overall sound quality produced has to be heard to be believed. Plus the sound is the same on AC or batteries at least for the four hours I ran mine the other day on (NiMH rechargeable) battery power. Otherwise the build-quality is fine.But it is the sound that counts and, in my opinion, the sound this unit produces is absolutely first-rate.
Some people have complained about a perceived lack of bass but take my word for it - it's there and in abundance should the music require it. (I listen almost exclusively to classical music). I have been a "hi-fi-natic" for over fifty years. You'll never regret the purchase.==================================================================================================================================Update: December 24, 2009I just received a pair of Dayton B652 6-1/2" 2-Way Bookshelf Speaker Pair and these speakers, in conjunction with this amplifier, are what I shall now be using as my sound system in my bedroom. 40-256); the sound quality was adequate as would be expected from these speakers. and it sounds really fine. The combination is really superb and the total low price is irresistible.
It stayed out from 7:30 PM to about 11:30 PM - but because I had this amp as well as a battery-operated CD player, I enjoyed fine music all through the night, albeit in the dark).This unit is so small that it will fit in an ordinary pants pocket. Of course everyone is entitled to their own opinion but it is my opinion that a prospective purchaser can safely ignore any negative comments made in other reviews of this Dayton DTA-1 Class T Digital Amplifier 15 WPC, especially about build-quality - with only one minor exception: the batteries are a bit tricky to insert and remove; the spring connections could have been of better quality and somewhat more recessed. I do know that this little amp would drive the Klipschorns to ear-splitting levels; setting the volume control to about 2:00 produces extremely loud sound in my room with my Pinnacles, too loud for me to endure for more than a few minutes (1:00 is about right for me).The price, $44.80, is positively astounding. (Just as I had inserted the batteries to try the amp out that way, our power went out. If used with good-sounding (most important) and efficient (at least 87 dB [1 Watt, 1 kHz, 1 Meter] speakers), one will have a fabulous sound system - at a very low price (depending, of course, on just how much the speakers cost - really, this amplifier deserves the very best, again in my opinion).I also tried it with an old pair of Realistic Minimus 20 (Cat. This kind of money for this kind of sound quality would have been inconceivable even just ten years ago.Buy one. I now own TWO of these extremely efficient and great sounding amplifiers and I give it my highest recommendation.
This little gem runs rings around any amp or receiver from the big box stores and it's sound quality rivals high end gear. I resisted buying a T-amp for several years as I just couldn't believe anything this cheap could be any good. Well I was wrong and all the hype is true. Match it with some good efficient speakers of around 90db and it's all you'll ever need.Buy the $78 T-amp preamp and you can hook up multiple input sources including a phono and use the higher quality preamp volume control. The volume control on the T-amp is so small it's difficult to use.
