Im not sure if everyone knows thiis and is in the common knowledge department yet, but iPhone and iPod touch devices will play hi rez flac files. It has to be iPod touch 2nd gen or newer or iPhone 4 or newer and you need the camera connection kit. There are a couple choices of DACS you can use...

Has anyone had the chance to compare the Cardas Clear Light cable to the Silver Dragon v3 cable on the Sennheiser HD 650?

Hey everyone. I haven't been on this forum for several years but now I'm back. Because of this I really don't know what the new hot amps are anymore! Please recommendations! Looking for something battery operated to drive me Cardas EM 5813 headphones. Source will be an iPod 5.5 gen or an Astell...

Anyone tried the new Apple in-ear headphones? They are only $79 and feature a dual driver design. How do they compare to others of similar design? (Ultimate ears, shure?) I know I posted this to the wrong forum but they havent added a way to edit it and change it to the correct forum.

I made a CMoy based around the OPA2107AP opamp. For the power caps I used Elna Cerfine 470uF 16V caps. I used PRP PR9372 1% metal film resistors. For the input caps I tried on a few different caps until I finally settled on the Mundorf M-CAP® Supreme Silver & Gold 1uF caps! So what does it sound...

I was decided to try the OPA2107AP in the CMoy. Heres what I found after I let them burn in for about 5 hours: In 1 9V CMoy. Clear midrange and nice airy highs. Low end was a little subdued and not quite as full as the OPA2227PA. In 2 9V Cmoy. Little more bottom end but and a stronger...

How good sounding are these caps? Are these vintage caps preferable over the still produced Sprague Orange Drops? I have access to a ton of these.

I have a 22000uf cap I want to test. Its way to big to test with my LCR meter so what is the best method to test that this thing works? I want to use it as a stiffining cap in my Sonic T amp. (oh yea...i found it in one of my parts bins, hence the need for testing...)

I was wondering if anyone knew of a chip that will do USB line out, line in and digital out? Im not sure any of the TI USB D/A will also do line in so it will probably have to be a 2 chip solution.

One of my new years resolutions is to get all of my electronic parts more organized. Id like to see pics or hear suggestions for ways of making this happen! I currently use large fishing tackle cases, but I have long since run out of room in them. To give you an idea, my vacuum tube inventory is...

Does the HD650 cable fit on the HD600? The only reason I ask is the HD650 cable from the Sennheiser website is $10 cheaper than the HD600 cable and it is gold plated also!

What are your favorite electronics magazines. I am looking for some good magazines to subscribe to that have electronic circuits to build. It doesnt have to be just audio, I like to build any type of circuits....

if you have found a suitable wallwart power supply for this amp please let me know the make/model of what you have. It needs a 12V center positive 2.1mm >1amp power supply. not interested in batteries you may have found to use....

There are no more Alien Dac boards for sale What other dacs can I build that boards are still available for? I prefer to have it PCM2702 or PCM2704 based.

Does ayone have a PPA V1.1 board they will sell me? If so PM me. Thanks

Has anyone actually fried the buffers in their PPA from unplugging headphones while the amp is on? Is it ok to unplug and plug headphones as long as there is no music playing if the amp is on? And if I goto the diamond buffers is this still an issue? I am using the Nuetrik locking 1/4"...

Are the diamond buffers for the millet amp still available? If so where can I buy them from?

Someone please help me bias my PPA into class A. Tangents instructions are too vague to understand. I am using 2N584 for Q1 2N5486 for Q2, 1K for R9 and currently i have a 500 ohm in R8. What resistor do i measure the current across and what should it read for the opamps I am using? My opamps...

If you are one of the selcted few on this planet and are simply addicted to stereo equipment than I would like to hear your stories! I'll start.... At first it seemed innocent. You know, saving up my allowance for that new walkman. I made it into the 90's virtually stereo free (except my...

Im wondering what your is a great sounding portable cd player. All i have ever owned is sony but have not bought one since the mid 90's. Are they any good? Like the D-EJ2000 any good? Seems to me for $159.95 i shouldnt expect much (http://cgi.ebay.com/ws/eBayISAPI.dll...ory=15054&rd=1) but i...

Hello, I would like to hear your recommendation for a headphone amp to use with Sennheiser HD600's. I have this big empty bottom rack to fill up. Of course when you own this you don't use headphones very often but it would make a nice addition.

I am curious what it cost you in total parts to build a PPA?

If R2=R6=10x( Volume pot) than if the volume pot is the reccommened 50K, why is R2 and R6 listed as 1M resistors? Shouldn't they be 500K resistors?

I would like to know how these two amps would compare to each other. I would be using them to drive HD600's.
