Not as if UHA-6S mkII needs any lower gain. It's within center 33-66% with all IEMs I have - there's no appreciable channel imbalance. That's with or without eq (around -9 dBFS "average"). Of course with the low gain. You'd need a way hotter source than its DAC or analog output of most phones, MP3 players etc. to have to tweak the knob down a lot.I'm not sure why my pot seems too easy to tweak accidentally. It can be turned with a single finger - so pocket friction tends to do that sometimes when it's in pants or jacket.The DAC isn't much worse than ODAC actually - it's mostly hampered by the USB interface chip. It is very slightly worse if at all (I'd need an actual double blind test), definitely better than, say, FiiO E17 or Prodigy Cube - both based on Wolfson DAC chips. Not that ODAC with any reasonable amp would be pocketable... (You'd need to rework power supply too!)I measured that with the ADA4898s, it loses ~20% battery life - making it still huge, way larger than FiiO E17. I'd estimate that OPA627 and AD797 it'd lose about the same amount. That's a 2x difference in opamp idle current at work. (~8mA vs ~16mA for a pair)Takes more than a day to get discharged, unless you use SPDIF on battery, in which case it takes about 8h - both coax and optical. USB is on par with analog, bit shorter maybe.
Just curious, does anyone know what the most powerful/best candidate for a portable amp to power a HE-6 on the go? I've owned it a couple of times now, and always end up underwhelmed by the performance on portable amps. For home listening I've driven it previously with the monster known as the Pioneer Reference Power Amplifier, which it sounds heavenly with - I just like having the option of taking my gear with me.... I know the HE-6 seems like a very silly choice keeping that in mind, but i just love the sound of it.... so what can you do...

sort of random question but what's the best portable DAC out there that works with an iPad and a PC/Mac?I'm a bit sad by having to downgrade from ODAC, if I go with the Leckerton route. but it just seems like a solid deal.I'm skipping the earlier suggested FitEar 334, as I missed out on demoing them. but will likely get the hifiman RE-600, and a pair of gaming friendly headphones (ATH-AD900X) for home use.OR maybe I'll try to make a battery pack for the ODAC as it's so tiny and cute, and get a separate amplifier.which then would lead to... what to get? I really like the form factor and physical design (vol control is great) of the C5 but I didn't really get a sense of the sound quality...always thought I'd never get a portable stack as they seem kind of dumb, but I figure this might be my most used setup so why not look into what's available!all roads still lead to Leckerton? it would be quite noticeable from the iPad I am sure, but it'd be my only DAC until I decide whether to get STAX or not later on. the CLAS just seems a bit expensive, I heard one and it's great but not 700 or however much it is great. fostex HP-P1 seems OK but not great either? is it even better than the Leckerton?thanks again, and sorry for indecision.
If you just need the DAC does the DACport LX work with the iPad and a CCK?
