I have just updated the review to include the following:
Update 10-5-07
Leckerton Audio UHA-3
Info: [URL=http://www.leckertonaudio.com/[/URL]
The UHA-3 was loaned to me by it's maker, at my request. It's got a USB DAC, which I will comment on elsewhere, but which I will say here works very well and sounds very similar to the analog input performance which I detail here.
Build Quality: A: Well built in a nice metal hammond case. Nice faceplate and knobs. Batteries recharge with the USB connection, very nice way to go! Power switch on the rear, separate from the volume knob is also very nice IMO. Well built little amp..
Treble: A-: Nice, sweet, grainless, and clean, but slightly laid back. Lacks ultimate air and extension, but still very enjoyable. This may be what makes the soundstage seem slightly small, though.
Midrange: A-: The midrange is open, lush, inviting, and nicely transparent, although not quite as much so as the top amps here. It's not the least bit too aggressive, but it is just a tad warm of neutral. Still, here again, very enjoyable presentation.
Bass: A+: Bass lover's amp to be sure. Great impact, depth, punch, and definition. Really enjoyed this part of the presentation.
Neutrality: A-: Slightly warmish sound. More so even than the Meier Move, but not so much that the amp sounds colored, just a tad mellow.
Soundstaging: B+: The soundstage is slightly small feeling. Instrument placement and image specificity is good, but it seems like the stage is a little too shallow and a little lacking in width. Still, not bad, and not a fatal flaw at all.
Transparency: A-: Loses just a little for a slight hiss that is present at any volume level, but in general, an open, transparent sound that's very enjoyable.
The battery lasted me over 24 hours on a single charge. The UHA has a lot of nice features, and it sounds VERY good. It's easily worth the asking price, and belongs in the top tier of portable amps. I was really impressed. The quality of current portable amp offerings is stunningly strong, and the UHA-3 is no exception. Nice job to Leckerton Audio.
Conclusions (10/5/07)
OK, so now its now 25 amps! Here is my view on how the amps stacked up. Note that the sum of the "Grades" I give does not always tell the whole story in how I rank them, since the whole is sometimes greater or lesser than the sum of the parts, and I am often forced to split hairs here, since the list has gotten so long.
