never mind

I feel having a variable output wallwart will be very handy when testing the new assembled gears. a DC wallwart with 5V-24V with 2V increments will be very nice, any recommendation?

I was always under the impression that as balanced configuration, XLR connector, which equals to balanced connector, has to be 4 pin, L+, L-, R+, R-. But today I found that I was wrong? So XLR is actually 3 pin with +, - and shielding, so the balanced amp output has to be 2 of 3-pin XLR...

Dear Yishi, The ARIA will be shipped today to your home address. Delivery by regular postal services to the US normally takes around 2 weeks but be aware that delays are not uncommon during the X-Mas season. Please send me a note as soon as the amp has arrived. Cheers Jan

Is this normal or what?

I was trying to modify my previous HD600 cable into balanced 4 pin XLR cable. I realized that most stock cable of headphones are 3 leads instead of 4, the ground of left and right channel is not separated. This makes recabling of headphone into 4 pin XLR very hard. I know stock HD600 cable is 4...

emm, both candidates are down by you guys, all right. any way, I trust you guys more than the Chinese designer, I talked with him on MSN messenger before and he seems pretty nice guy. any way, getting down to my list, this is the only Chinese DAC choice I have on the list now. any...

I bought some bulk cable and connectors in the last few weeks. So it's a good idea to make a spare cable for my HD600. Here is some guide for the recable: I used NEUTRIK NP3X-B 1/4 stereo plug, you can find it here: http://www.partsexpress.com/pe/showd...number=092-320 This plug is really...

I am making a pimeta for my friend, just realized a question, do you guys populate C1 in pimeta? I read tangent explanations about input cap back when I was making my first CMOY. http://tangentsoft.net/audio/input-cap.html I know C1 is to remove the DC offset from source, I was under the...

they should arrive at Headroom early this week, according to one sales rep. so they should be shipped by the end of the week...

I got some teflon insulated, silver plated copper stranded cable. (a lot of descriptions eh?) they are like this: http://cgi.ebay.com/50-ft-22-AWG-Sil...QQcmdZViewItem I tried to strip them by my wire stripper. Goshhhhh. they are extremely hard to strip!!! 100 times harder than stripping...

Received my DT880 this morning. got excited and open the package. Haven't listened it yet, workmanship seems OK. I noticed that there is only the headphone and extension cable and warranty card in the alu. box. There is no manual whatsoever. Of course there is outter paper wrapping around the...

anyone lives around Los Angeles, or any where near SoCal? Do you guys know is there any B&M headphone store here? I really wanna have such a place to walk in and listen, compare...

decided to recable HD600 from the stock cable. But after I cut off the wire from the two connectors, I realized a problem, which one is + and which one is -? I know it's actually AC signal so there is no real + or -, but I kinda remember someone mentioned the two leads of the speaker or phone...

Hi, guys, since I am finishing my current projects. I am trying to make a priority list of AMP projects: I am considering: M3 http://elvencraft.com/mmm/ http://www.amb.org/audio/mmm/ White Noise MKII http://www.wnaudio.com/ Millett's Hybrid http://www.diyforums.org/millett.html...

Ordering some 3.5mm jacks, see this PDF: http://dkc3.digikey.com/PDF/T053/0287.pdf Why the same jack always have 3 versions, 3 poles, 4 poles and 5 poles. Such as fig 58, ABC versions. Wouldn't 3 poles be enough? What's the point of the 4 pole and 5 pole version? or they have some special...

dude, check this out: http://www.techdesign.be/projects/020/020.htm Is it possible to make a MP3 player out of this: I want to mod it into: 1. Use regular 3.5 inch hard drive instead of MMC/SD card. 2. Use STEPS as power supply. 3. Line-out only, make it possible to hook up your own amp...

From this list: https://www.wirecare.com/wirecarephp...hp?prodline=ES Which one or some techflex do you guys usually use? I noticed in the sticky thread some used PET and a few used Teflon (so darn expensive, over $1 per foot!) What else do you use?

pics coming... right channel no DC offset, left channel has 12mV DC offset. Is that normal? The way I measure is to connect power, no source connected, measure the OG to OL and OG to OR using DC, mV option on DMM, is that correct way to measure DC offset?

Hi, guys, any opinion on that? I have a pair of 2 year old KSC35, I don't really like the sound sig of it so it stays like new condition. I am thinking putting the driver into a full size can housing and recable it using silver cable. any opinion which brand of cans are easier to open up?

Is this POT discontinued? I can't see it on mouser, digikey, allied... anywhere... The new product line seem not including the build-in switch, only the regular POT. anyone knows where to get them?

Hi, guys, when I was hunting for resistors for my MINT and PIMETA projects, I noticed that tangent used VD RN55 sery instead of my usual Yageo 1%. I know they are both rated 1%. Is there significant advantage of RN55 over Yageo? I find that RN55 is 1/8W, so maybe not QUITE sufficient for...

first let's forget about the coloration from source, IC, AMP, HD, let's say the pure "duplicate" of the original sound is considered as "perfect" SQ. there is one way to perfectly measure SQ: 1. take a dummy head, install Hi-End microphone in it, like the ones recording studio used to record...
