Centrance Dackport


Pros: Size, sound quality, bus powered and still big voltage swing

Cons: Gain is a bit high - sensitive headphones mean little volume travel

A great, well built, great sounding dac with class A amp.  Nice analog volume pot, nice form factor, nice build.  Output impedance is a bit high for a portable, at 10 ohm.  Centrance will modify it to 1 ohm for a mere $100.  I have not bothered.  My headphones are 80 ohm, so they barely meet the 8x output impedance rule.  I always use my Pico slim between my dacport and my iems.  Nice piece of kit, but pricey - my only complaint.

Headamp Pico Slim


Pros: Digital Volume Control! size, battery life, sound quality and build quality of course!

Cons: Wow - Pricy!

First - I bought mine used - my complaint on price is based on new price of $400, though I guess it holds value...   OK, that's out of the way.  Justin at Headamp builds some of the highest quality hardware I have ever held in my hands - truly beautiful.   Sound quality is outstanding - close to wire with gain as I've heard.  I have yet to run the battery down before I get around to a recharge.   The volume control is second to none.  If you listen at low volume levels with sensitive headphones and iems, the Pico Slim is the best there is, and I've tried a few in my search.  It is literally indispensible to me.  If this last bit...

Beyerdynamic DT1350


Pros: Sound Quality, form factor, cool case, isolation

Cons: price, sensitivity, sort of uncomfortalbe

I love them - great sound, a detailed, slightly warm, non-fatiguing sound signature.  They are very portable, cool looking, well built.   I tolerate the lack of comfort and the fact that they are quite sensitive, and leave most amps with very little volume travel.

1964 Ears Quads


Pros: Price / Performance, Customer Service, Sound Quality

Cons: Custom fit - Excellent when it fits, an effort to get there

The quads sound fantastic to me.  They are my preferred sound signature - all the detail, very present bass, but honestly not fatiguing or overpowering, very slightly attenuated treble.  All this leads to a detailed yet warm sound, and the slight roll off on the treble keeps them from being fatiguing.  These are concieved as a stage monitor first, and as a high end pair of headphones for musical enjoyment second, which always works well for me.  So many "audiophile" headphones have some sort of built in "wow" factor somewhere in the frequency band that eventually makes them fatiguing to me.  The accentuated bass comes closest to this in these headphones, but...
