I love this new generation of bluetooth dac and their apps, and don't want to switch back. But the ES100's built-in amp is not really able to drive some of my less efficient full size headphones. Anyone else has this issue? Does anyone use a good ol' analog portable amp to pair with the ES100...

Swore off buying more headphones last year but the bug has bitten back in a big way. However, I want to do it in a more wallet friendly way. So here’s where I’d love to get your help: I want to get a few (3+) ChiFi IEM/ earbuds that run the gamut in terms of sound signature, drivers/armatures...

Can you tell me which version this is? Pro? 32 ohm? 250 ohm? Thanks! Sent from my iPhone using Tapatalk

This review from a great but non-Headphone recommendation site http://www.kk.org/cooltools/archives/005854.php#disqus_thread has me wondering if anyone on head-fi had tried this Coby headphone yet.  $30 and active noise cancellation?  Sounds like a possibility for investigation, at least.  ...

I would like to build a simple amp to drive a simple 8ohm speaker housed in a small box, for very casual listening from an iPod. The considerations are that it's cheap, small, and battery powered. I researched turning a CMoy into such a beast, but in an old thread AMB pointed out that you may...

Both Mouser and Digikey are out of stock, and I just got an email from Mouser saying that they don't expect any until end of March. Does anyone know of a source for them? I'll settle for one just to get my first CMoy going. Thanks.

Can someone help me understand why some headphone amps are more suitably used as preamps? I've seen that mentioned a few times here or at other forums, and I never understood it. I'm guessing that preAmp is a current multiplier, and so is a headphone amp, and a power amp is a voltage...

Has anyone done a recable of the HF-1? Would like to know how you went about it, particularly great if you have step by step photos. One of the things I really dislike about the HF-1 is that cheap feeling cable that kinks and twists. The sleeving is some uber cheap vinyl, doesn't flex well...

Okay, the Official K81DJ thread has 100 pages, and even searching within the thread didn't reveal the particular POST that shows the removal of foam and the use of bluetack. Can someone just post the pointer directly to the POST in question, please? Someone should consider locking that thread...

Where do you guys get cheap hookup wires? 22awg or 24awg, prefer a multi-color set rather than one big spool of white. $25 for a spool of one color is alot to spend on wires, and yet that's what Mouser/Digikey asks for.

Hi: I'm going to build a Tangent CMOY as a refresher soldering project, and been studying the parts list. I did notice that the schematic calls for two 9V, which works for a mint tin, but I'd like to use the recommended case from his parts list, which has one built-in 9V battery slot. Is...

Over at the DIY forum on Headwise is alot of activity on amp designs that I haven't seen reviewed over here. This post in particular list all the of the amps that one can build/have built for you: http://headwize.com/ubb/showpage.php?fnum=3&tid=6339 I'm wondering if anyone has done...

Wondering if anyone has tried making foamies out of ear plugs for E2/E2C. The plastic tubes for the E2 is quite a bit larger than any other IEM that I'm aware of, and so I'm having a hard time finding a tubing that fits. I've tried 1/4" vinyl tubing and it's still too tight on the shaft, whereas...

I'm wondering if there are users of the current emusic.com. I am interested in their selection in Jazz, Electronica, and Classical. How do you like their selection? You think it's worth it for the fee they charge? How is the quality of their rip? $10 for 30 non-DRM tracks a month isn't bad if...

I've tried searching for this both here and on fixup.net, but I don't think I am getting a clear picture of why Dr Xin came up with the LE. For instance, I've heard that he and others were very happy with the SuperMicro IV's sound, but not with the SuperMacro IV, and somewhere along the line...

Haven't listened to the CX300 for a long while, ever since the AKG K81DJ arrived. Pulled it out today and listened to it out of an iPod and starting hearing a "distortion", for the lack of a better word, that happens during a song's louder passage for a transient second. Seems to be worse with...

Thanks for the tips on how to manage the Y-junction on a double sided headphone rewire. I think I am going with the pipe+heatshrink routine. At this point my plan is to just try a Canare Mini StarQuad wire, to a right angle Neutrik connector, leading upto the Y. However, I want to ask what do...

I'm attempting to recable my first set of phones, and am thinking of using the silver plated cooper cable and gold mini jacks with sheathing. The one part of the design I'm not sure of, is how to handle the Y junction where cables split off to the L and R drivers. I was hoping to find...

So I enjoy the HF-1 (with Senn 414 pads), it's a much more neutral and detailed can than anything else I've got. But I sold my SR-60 and I sort of miss its fun aspect for rock and such. HF-1's bass is much tighter but there's something to be said for thick bass. So I'm considering a new pair...

I'm looking to replace my Shure E2C tips, but am wondering if there are any aftermarket tips worth trying. I've tried the plastic tips and the foam tips that came with the phones, but neither sets (in all sizes) really does great, though the med foam tips are about as close as it gets. Any...

What is the minimal equipment that I'll need to hook up to listen to my turntable on my headphone? I assume I'll need a phono stage at least, and some sort of amp. But can I get by without a pre/power amp? Can I just hook up the phono stage directly to a headphone amp? Thanks
