Setup:
iPod Touch 3rd gen, Fiio L9 LOD, Leckerton UHA-4 using opamp AD8610ARZ (gain setting is on, cross feed setting off), DT1350 with Sennheiser HD25 pads mounted on cups, source Apple lossless 16bit
First the great news,the lows now have a little more authority and body and they can now punch quite nicely meaning percussion is very very nice now. Although I'm finding the bass has a touch more body note decay is still very quick and tight in the low end. The highs aren't as splashy and the upper treble is now clearer and not as grainy. Sound stage seems to have slightly expanded and instrument positioning has improved. The upper mids are now controlled and although still energetic sibilance has been almost eliminated. The mids for me is where the big difference is specifically the vocals. Vocals on the DT1350 I've always classed as excellent but with the UHA-4 vocals now sound heavenly. I was in awe when I heard Melody Gardot or Anette Olzon from Nightwish sing and it felt like if I closed my eyes they were there. String instruments are no longer blurred and the listener can practically pick out each individual string as their plucked. Electric rock guitar tonality is now better and I'm hearing more detail throughout the whole sound spectrum. I used to amp the DT1350 using a DIY amp I called Marilyn and the presentation on that amp I could only describe as fluid. With the UHA-4 the word fluid goes out the window and the only words I can use to describe the presentation is quick, detailed, refined and natural. Another word that comes to mind would be attack because the DT1350 takes fast aggressive passages and hits the listener in the face with it.
The bad news, this amp paired with the DT1350 has shown me how important source can be and has showed me how many of my favorite songs are junk. Badly recorded music with this combo will sound like complete garbage. Tonality will sound off sound stage has little or no depth etc. and vocals sound forced and very unnatural. This can is definitely not the can to use if all you have is mainstream low bit rate songs with little or no quality behind it. Some other bad news, although the bass now has more authority these cans for me personally still don't perform to my satisfaction with bass heavy electronica music. When I have more time I'm going to try throwing some trance and hardhouse at them but from the little I've experimented with this combo bass heavy music still doesn't work, The DT1350 just doesn't rumble on the low end for a satisfying listen with bass heavy music.
Looks like I'm eating crow, when I first got my DT1350's a few months ago I was of the opinion amping wouldn't bring a noticeable difference. I've never been so wrong and I now feel quite foolish I jumped to such an assumption. Overall I'm really happy with the results and I'm loving these cans the more I listen to them.
Velour or pleather pads? Also do you rest the hd25 pads over the plastic cup of the DTs or do they creep into the gap between the DTs cup and their original pads?
And yes DT1350s are lovely cans with beautiful mids and they are so unbelievably quick! I use them amped with my FiiO E17 or my home setup (Keces DA151 -> Meier Arietta).

Nice comments digital freak. Don't worry about the early negative comments and thoughts about the DT1350's. I auditioned them locally after reading so many reviews and even with my Alo rx2 driving lossless tracks into the Beyers I still found them to be particularly average. Well perhaps not average but certainly lacking in bottom end in a big way. I was almost tempted to buy some audio technical esw7's instead. I am glad that I ignored my initial views and relied upon the many glowing headfi reviews. These cans paired with the iBasso pb2 with balanced wiring are heavenly. I am loving them.
