I just found out! Very sad indeed, I myself have built a couple of Cavalli DIY amps( EHHA, Bijou) which I love. Thank you Alex.

Try grounding the alps pot. Wire one of the metal screws at the back of the pot to ground on the one of the boards.

Nice pics, I love Tokyo!!

Great thread! I really enjoyed reading all the comments. I agree with tomb on that cheaper stuff from China has at least in part killed much of the DIY community here. Myself I'm guilty of purchasing cheap Chinese kits, just solder the parts put in a case and enjoy. I remember when I put...

Check for soldering bridges specially around the op-amp.It is a simple circuit, if you own a multimeter you should be able to do a continuity test in no time.

I was there on Saturday I really enjoyed the shown, however it was overwhelming. All kinds of amazing headphones and related gear. There were about 5 floors full of equipment and people. It was almost a mission to audtion some of the new stuff. I did not meet Currawong however I met Jude, nice...

My flight will arrive late Friday night, I will try to be there by 10:30, looking forward to meet all of you.

I read the article and to me, it all makes perfect sense. I've also organized double blind test between ODAC + O2, pupDAC+AMB M3 and Cambridge Audio Azur DacMagic+ dynalo headamp  and a   combination of them, and I or my friends could not tell any difference between them. I know the article is...

Thanks gixxerwimp, I am planning to go but it all depends on the dates of the event. Late October might be good for me.

2015 Fujiya Avic autumn Headphone Festival dates? it is usually held in October anybody knows the exact dates?

All HD 25-1 parts are replaceable, Why not get the original one. those cardas and oyaide are expensive and imho you will not perceive better sq with them. 

2K is a lot of money for headphones and at this price range you are not only paying for sound quality, but also build quality. Those pics show a poor manufacturing quality control for a product that is suppose to be top notch and one the best in the world. No excuse.

Beautiful! congratulations.

Hi Mr Rick, could you please post the links to the books above? Tx.

It sounds to me like Fiio won't be implementing fast wheel scroll  for X1/X5 anytime soon. Read the answer from  FiiO-Shadow at the end of this post: http://www.fiio.me/forum.php?mod=viewthread&tid=40101 I love the sq of my x5 but the scroll wheel speed is a real disappointment.

Hi jcx, I checked the operating points using the schematic found here http://www.djgardner.com/headphone/gilmore/dynalo/layout/Rev-C/Dynalo%20-%20Operating%20Points.pdf as reference, I calculated the ccs currents and got 2.13mA and 2.17 which are a bit high for the recommended 2mA.      As you...

Hi, I recently finished putting together a dynalo amp that's been in the pipeline for quite sometime. Upon powering up all the initial voltages checked Ok as per the construction guide in http://www.djgardner.com/headphone/gilmore/   The amp is extremely quite even when using low impedance...

Thank you 2leftears I really enjoyed the reading. Good stuff!

Congrats Mullet nicely built! I've got the EHHA kit from glassjar, but haven't had time to start building it.

Hi, anyone done a comparison between e12diy with any opamp/buf combination and the stock12 ?

Hi, where exactly are the new e-earphone stores located? tx.

Hi, I read somewhere in this tread that the Torpedo might not be a suitable amp to drive orthodynamic headphones. Has someone actually used it with something like Hifiman HE 500 or LC2?. I am tempted to purchase the kit from Beezar , however not sure it will drive my orthos to a proper  volume. Tx

Hi, Great review and nice pictures. You offered a good impression on the sound signature. They are really beautiful and as you mention the construction seems solid. One thing though, the cushions are not real leather please see the video below: http://www.youtube.com/watch?v=OB5Y-ocQfYc
