I just bought a Pimeta amp from Manvin (m3ta1head). His communication was so fast -- he would reply to my messages within an hour about. He shipped it really fast too. I paid and he shipped it the next day. Then the next day it was in...

I have some new free software for the community. Frequency response is one of the most important measurements of audio equipment. I wrote a program to automate the task of measuring it, which I decided to share. Unfortunately it does...

I've noticed some noise-cancelling headphones run on a single AAA battery, and also I have seen amps running from single batteries, but I don't remember who makes them. I'm wondering what kind of interesting power supplies these things...

I built the project on HeadWize called "Build These Noise-Canceling Headphones" by Jules Ryckebusch. The circuit does provide noise cancellation but I'm trying to improve it. So far I have added bass boost to the microphone...

I am planning to build a meta42 and a linear psu for it. A few questions: 1. The meta42 PCB can be used with a TLE2426 rail splitter for virtual ground. However, if I build a psu, I could just make the psu have positive, negative,...

Question about ordering from Analog: I plan to build a META42 and want the ad8620. When I go to the Analog web page they require you to register, including all sorts of company info. Now, obviously I don't represent a company. What do...

Thanks for all the comments. Everyone seems to agree that a cmoy would be a better first amp because it is easier to build. I'll take your advice. A couple questions: 1) If I decide to play with opamps, where do you guys order Analog...

Quote: I think that those questions would require having built both amps and that's why no one has responded yet! I was afraid of that. I can't believe nobody has built both of these! Would anybody be interested...

Hello! I've decided to build my first headphone amp. I have very little electronics knowledge. I mean, I have built many circuits, but I know very little about how the work. I have spent alot of time the last two days reading the...

Thanks for reading this, my first message on this board. I need to get a pair of headphones. I want a closed design that gives the most isolation from outside noise possible. I don't have a headphone amp, and it's not in my budget to...
