5.0 out of 5 stars A Small-in-Size, Efficient, and Superb Sound Amplifier June 25, 2011

By Lawrence H. Bulk TOP 1000 REVIEWERVINE VOICE

I have owned a Dayton Audio DTA-100 (the original version) for a year now and, just two days ago, I received this Dayton Audio DTA-100a Class-T Digital Amplifier 50 WPC, the upgraded version.
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 ›
