Does anybody know what the optimal impedance is for the A8?   -sheldon

I just picked up a pair from Echo Audio in Portland. The build quality is certainly impressive, and I like the included case.   The sound profile leans to the lows, dramatically. This is outside my normal palette, but I'm hoping to adjust to it over the next few days. My primary set ups are...

I will plan to stop by near the end of the day. Thanks for the invite @grizzlybeast !

I'm considering coming up from Portland. Is anybody interested in hearing the Coffman Labs Prautes? https://www.cypherlabs.com/products/prautes/   -sheldon

It's all good. I know our community is pretty inactive. I haven't even put a meetup together here in more than a year. Thanks for trying, though. :-)   -sheldon

Clearly a Seattle meet, not that you 'owe' us Portlanders anything :-)   Please post in the Portland thread if there is ever a meet 'in the middle'.   http://www.head-fi.org/t/723990/does-anyone-know-when-the-next-portland-oregon-meet-will-be   -sheldon

I prefer to use the Clip alone, without the C5D.    I bought a C5D because it has both a DAC and and amp. It colors the sound in a way I didn't like, no matter what kind of headphones I used. Running my HF5 with the Clip alone is very neutral and clear, which I prefer.   The gain and bass...

We haven't had an event for quite some time. Has anybody been active?

  Yes, I agree. I prefer my Clip over using my JDS labs C5D with my HF5. I don't think I'm going to bother with any other portable DAC/amp since the Clip sounds great.   -sheldon

  I have a headphone amp which has a knob to change the impedance. 8, 32, 128, and 300. I can say with great certainty that changing impedance does have an undeniable effect. However, I understand that 2 or 3 ohms won't make much a difference.    I guess what I'm asking is what is the optimal...

I just noticed the Geek Out IEM 100 DAC/Amp combo unit operates at .47 ohm.    http://marketplace.lhlabs.com/products/geek-out-iem-100-usb-dac-and-headphone-amplifier   Does anybody know the ideal output impedance for the various ER4 models?   -sheldon

  I haven't heard anything good about the tips from Ety, but those look great. I have already had impressions taken, maybe this is my chance to finally use them. Thanks for posting.   -sheldon

  I actually had a C5D for about two weeks and couldn't stand it! I found that the gain made everything feel harsh, and the bass boost made everything feel imbalanced. Lots of people like that sound, but not me. Even without the gain and bass boost, the highs seemed crunchy and the overall...

  What is the optimal impedance for the HF5 and ER4?   -sheldon

Good info, I may end up getting a separate DAC and amp rather than a combo unit. Not so concerned about portability, just want a smaller setup for my desk at work. I <3 my HF5.   -sheldon
