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

For the record, I purchased a JDS Labs C5D to pair with my HF5. I also own a Sansa Clip+. I do not like the sound of the C5D. The gain sounds awful and the bass boost is not useful for my music. It really overshadows the mid-lows that come from acoustic instruments. And the highs did not sound...

I use this as a DAC for some self powered JBL monitors (LSR 2300). I use the right / left outputs on the back. Setup sounds pretty good.   However, I don't like it much as a headphone amp. The overall blend isn't fantastic. There seems to be a gap in the mid-low range where things don't come...

  I'd love to find one of these, not seeing them anywhere in that size though :'(   -sheldon

Thanks! The colors are not my favorite, I'll wait and see if there are better options out there. Otherwise this will work. Cheap too!   -sheldon

Has anybody found a nice fitting bag or case for the C5D?

I called Echo and spoke with Damon Coffman about the details of the event.    http://www.head-fi.org/t/724385/portland-or-coffman-labs-cypher-labs-at-echo-audio-june-28th-3-7pm   So excited!

Echo Audio is hosting an event for the launch of a new headphone amp from some great local companies.   http://www.cypherlabs.com/products/prautes/   The Prautes is a collaboration between Cypher Labs and Coffman Labs.    Echo will have plenty of headphones for use with demo. You're...

Does anybody have details about this event?   -sheldon

Hi,   The last one was great! But it mast have been more than a year ago now.   I'll get in contact with Echo Audio (www.echohifi.com) and see if they are open to hosting another event.   -sheldon
