The DTA-100a is a T-amp made by Dayton (duh) and includes speaker outputs and a headphone output. Well, here's the problem:



Poopy volume pot makes it even worse. There is a channel imbalance. I'm probably gonna return this.

These photos look like the ones from the original DTA-100- taken from the DIY Audio site. The DTA-100a is a revision- not sure about how the internals look, but the amp sounds fantastic with my KEF Q15 speakers! Haven't done much listening to the headphone amp though.

Are these pics of the unit you have?
 
May I ask what your source is?
 
Thanks

Good question!  That's some of the worst rework I have seen in a long time.

Any positive reviews I've read or heard about this so far had it driving high sensitivity speakers, not headphones. Besides, if you're primarily using headphones, a uDAC2 would be a better choice for the money, just a few bucks more; and if you need speakers to round out hte computer set-up, just get active speakers for use with the uDAC.

While that is true, I don't think that dismisses the fact that (perhaps only on speakers) its supposed to sound excellent as per reviews, which has me greatly confused.

As a headphone amp, I really like the µDAC2; when switching between the two I always settle on the µDAC2- the DTA-100a just lacks energy and clarity. But for driving my KEF's it is terrific! By the way, the KEF Q15's are pretty sensitive- 91 dB. To get plenty loud, I have the µDAC2 set at 12:00 and the DTA-100a at 10:00- thus still have plenty of overhead.

It seems as though you're using the analog out of the uDac into the DTA-100a.  Do you think you loose any resolution doing it that way?

How else would you run this setup? You have to run an analog signal to the amp (it doesn't have a DAC).

I own this amp and the fiio E7 this amp is great and as a headphone amp it sounds better than the E7 it also has 30watts into 8ohms of .01% THD and every soldered joints and components on the inside of mine is impecable. no imbalance or anything maybe yours was an older model but after 6 months mine sounds better today than day one
