I have had my Leckerton Audio UHA-3 for a few weeks now. I have posted a couple of reviews on it at: delete and WTB: Denon D5000 stock cable (found)

As a matter of fact I am listening to it at the moment using my 4th Gen iModded iPod Photo, a Revelation Audio Cryo Silver IC and my AKG K501. Some of the strong points are:

1. Excellent customer service w/ fast shipping.
2. Very well built, yes I do not mind the use of a "generic case". However in the case of the UHA-3 the end caps have been engraved w/ the name and identifiers for the various features.
3. Separate on/off switch from the volume pot. The on/off is on the back and it would be very difficult to accidentally move.
4. Gain switch (low - high) in the back. Also hard to accidentally move its position.
5. Shipped w/ an USB cable and Mini to Mini. The USB cable provides the source as well as charges the unit.
6. User replaceable battery.
7. Nice LED in the front indicating the charging status as well as the power status.
8. Volume knob has knurls so it is easier to turn.
9. Although the input/output are close you can fit a large plug, provided the other is an smaller one.
10. Priced at a level most could afford one.
11. With an additional 100 hours of burn in the graininess is gone and the amp has opened up. The veil is gone as well and the sound has a warm and elegant presentation. The amp has moved up a couple of notches.

Some areas to improve are:
1. The input/output should be reversed so it matches the majority of the portable amps. This is a very minor thing and should not stop anyone from getting one.
2. The use of SMT components prevents the average user from op-amp rolling. This would only be of interest to an small group of people, so again it should not stop most from getting one.
3. I yearn for a bit more detail and clarity, specially on the top end.

Nice MrArroyo!, I always enjoy your and Skylabs reviews, I too am finding this UHA-3 opening up a lot with burn in, I have about 100 hours now on mine, and starting to really enjoy this portable. I am finding the DAC in this to be a real treat with full sized cans and nice to just unplug and go with the IEMs. The fact that it charges through the usb, is a great feature, one less power supply to deal with and its always inconvenient to want to use it and there is no juice left... the UHA-3 solves that issue nicely.

As it settles in I also notice the bottom end start to relax a bit, which is most noticeable on my HD600s. The highs still seem to be just a tad rolled off, but only at the highest frequencies (somewhere maybe in the 18k beyond range noticeable on transients with cymbals on several passes of Der Trommler), and only on my HD600s the Grado 80s dont seem to exhibit that as much, but then they are brighter to begin with. its actually more pleasant on my Grados.

Its been said before but this is one sweet deal of a portable amp. I am willing to forgo my Hornet on the road for this amps sound, size and versatility, I know that is saying a lot... as the Hornet was my benchmark to date. I am looking forward to Nicks next product!

Bumping this thread that I found on a search. I've just purchased the UHA-3 this month and I'm simply atonished about the overall quality.

This is my first amp, so I don't have other references.
