Best portable amp/dac for Denon AH-D2000 headphones

I really enjoy my Bithead.  It drives the D2000 quite well and for a portable you cannot beat the quality.  I have had mine for who knows how many years and it is still going strong.

The Leckerton UHA4 does a much better job at driving my Denon 5000s than the E7 ever could. Plus it has emphasis on the mids while being incredibly neutral, you'd be hard pressed to do better for a portable DAC/Amp combo with them. I'm actually considering buying the full sized UHA6s as well for home use as I love the amp so much.

I mostly use it with my pc with foobar and flac files, my tv's headphone output and my zen vision m mp3 player. It needs both a usb and 3.5mm input and at least one 3.5mm output.

 

Thanks in advance guys.

 

P.S-Sorry for posting it in the headphone section but no one seemed to be replying in the portable amp forum and i need you guys' expertise.

You should be able to drive them on both low gain and hi gain. Did you consider the UHA6 though for those denons. The UHA6 would be a better amp than the UHA4 for full size cans and the price difference is worth it for more quality although the UHA4 is no slouch in that regard. But the UHA4 is more catered to IEMs while the UHA6 would be more appropriate for full size cans.
