The Darkvoice factory is located in Chengdu, very close to the epicenter of the recent Chinese earthquake. The guys there have posted some of the damage they incurred, pretty gruesome. ½ñÌì²ÅÈ¥ÇåÀí¹«Ë¾ÏÖ³¡ - ³É¶¼ö¦Òô·» - Õý¹æ³§¼Ò½»Ò×Çø - µ¨ÒÕÐùÒôÏì²ÄÁÏÍø...

So I've always drilled a couple of holes and then used a file to make the square. But this is really time consuming, not to mention the extreme cacophony associated with the filing. Anyone know of a better method of cutting out the square without going to a machine shop or resort to buying...

I've had my DT880s for more than two years now and I just changed the velour pads. The old ones were deflated and oily. The new ones are stiff and clean. Not only are they more comfortable, they sound better too!! I can now hear more soundstage, better dynamics and stronger bass. This is...

I was just thinking it would probably be appropriate to edit the small paragraph in the second post of this FAQ, under the OTL topology. The description of the OTL topology in the FAQ applies mainly to speakers. Since at least a plurality of tube headphone amps on sale are OTL, I don't think...

Here's the link to the English page. The company behind the Darkvoice line of headamps, Orphean Sound Lab in Chengdu, China, has been working on a new website. Looks pretty nice. Fittingly, the website's background is black. Here's a post on their forum with some new pictures of upcoming...

The sticker on the bottom of my black cube has worn off and don't know how to set the gain switches. Can someone who owns this amp kindly take a macro picture of the bottom of the amp? Thanks

The super E configuration for the Blackgates N series is well documented. Has anyone heard about it also being applied to the Nichicon Muse ES series? They're both nonpolar caps, so I assume it can be done?

Yeo from DIY Paradise recently added Rudolf Broertjes' SS I/V gain stage to his Monica2. I looked over the original DIY Audio thread and saw it works for the TDA1543 chip as well. Having also recently purchased a DAC-AH, I decided to give this I/V converter a shot. Here's the original...

I bought a pair of octal bases and two loktal sockets and proceed to wire the two together, taking note of the changes in pin-out Here are the two datasheets: http://www.mif.pg.gda.pl/homepages/f...127/6/6SJ7.pdf and http://www.mif.pg.gda.pl/homepages/f.../127/7/7C7.pdf On the...

Introduction: The Darkvoice 336 that some people here at Head-fi began taking orders on early last year generated tremendous interest in this Chinese headphone amp manufacturer. Its polished looks, meticulous construction and outstanding sound grabbed my attention as well. For a couple of...

So I completed my first STEPS today. I plugges it in and everything looks good, until I try to adjust output voltage (TP4 and TP5). Seems I can only adjust between 35V-29V. The trim pot does not go any further. Is there something else wrong or did I just buy the wrong trim pot? I'm using...

Does anyone here know of any stores in the Santa Monica/San Fernando Valley area of LA that sell electric parts (besides Radioshack)? I am 2 resistors short of finishing a M^3 (Mouser sent wrong parts!) and I just don't want to have to wait for shipping and etc. Thanks

I'm using n_maher's BOM to order parts for my M^3. There is a problem. The "Fairchild NPN BJT 2N3904" part number at Mouser was "625-2N3904". The website says it has been replaced by 512-2N3904BU. The "Fairchild PNP BJT 2N3906" part number at Mouser was "625-2N3906" but that has been...

So I put together a TREAD using Tangent's kit. Using a AC transformer, I plugged the TREAD into the mains. Caps 7 and 8 (10 µF and 22 µF) both exploded. It was like a mushroom cloud Turns out I switched their positions. So I bought the two parts again and tried again with the caps in the...

Hi, So I bought one of these from Mouser. I understand there's the T, R, S. What about the other side? It's "switched"? What does that mean? I just have one headphone connection. Do I just wire T, R, and S? Thanks

Hi, I'm building a tread power supply and I ordered the following transformer listed on Tangent's website: Alt. transformer, 115/230V in, 36V or +/-18V out, 700mA chassis mount Mouser part 546-185C36 http://www.hammondmfg.com/pdf/5c0022-23.pdf What is confusing me is the layout of...

I swear! The FEEL HP 200SE I ordered nearly 2 months ago just came in. This thing is massive. I don't think the pictures really show it. It is as big as a 19 inch monitor. It weighs as much as an unabridged dictionary. Here are some photos I snapped of it...

Hi Does anyone know of a good place in the Los Angeles (Westwood/Santa Monica) area where I can find a decent selection of headphones? Thanks
