I am as pleased as is possible with both of them. The sound quality produced by these amplifiers is nothing short of amazing.
Both versions use the Tripath TK2050 chipset which offers extremely - and I mean extremely - clean and neutral sound (at its true high fidelity rating of 30 W/Channel) plus very high electrical efficiency (> 85% claimed). It is as 'green' as it comes.
I had written to Parts Express asking them to tell me the difference between the -100 and the -100a; their technician's reply was that the new -100a has an improved headphone amplifier circuit; nothing else has been changed. I wouldn't know about this - I do not often listen to music through headphones and I have never tried using headphones with either of these amplifiers.
Via loudspeakers, the sound produced is the same with both models. And, as stated, it's just great!
I have read where 30 W/channel is "not enough" power. I disagree with that statement; how "loud" music sounds is a function of the sound amplifier power, true to some extent, but it is much MORE a function of the efficiency of the speakers used in conjunction with that amplifier.
Connect a pair of Klipschorns (sensitivity of 105 db/1W/1M - the most efficient speakers ever made - I own a pair) to a 30 W/channel amplifier and that system could "blow you out of the room" (maybe out of your house - maybe even off your block!).Read more ›
Dayton DTA-100a is a type T amplifier, it is a new technology. I bet that in few years, as this technology develops further and T-amps become more powerful, makers of old-style heavy and bulky amplifiers will have hard time selling their "dinosaurs". Note that this is a review for DTA-100a, not an earlier model DTA-100 (DTA-100 has a slight channel imbalance problem, DTA-100a does not). You can also find a detailed review on the web by searching for "Dayton Audio DTA-100a - class D integrated amplifier".
USEFUL HINT: if the amplifier's power indicator blue light is annoyingly too bright for you (as it was for me), then use a small piece of dark paper and a duck tape to cover and dim it.
P.S. Failed after a month (one of the audio channels died), but I got a replacement and I am still happy. They should had made it more reliable even if it would have cost little more money.

The Lepai 2020A amp sounds better than this. Lots of noise, buzzing, and just poor sound quality overall.Published 7 months ago by nathan
