Well, I’ve searched for a bit and can’t seem to find a thread for the Meze 99 classics, Im sure one is here somewhere, but this is more about the hobby that the phones so I’ll just throw up this post. I haven’t been “listening” to music now for the better part of 10 years, I know, it’s...

  I started working on a digital POT system for amp control. The idea is to use digital potentiometers (dpots) in place of standard volume controls and trim pots in an amp.   As can be seen in the photo, I have an arduino, a CmoyBB amp and a breadboard with an AD5206 chip on it. My...

Well, I was going to wait till I had this fully assembled and tested, but I changed my mind....   Here are a couple of pics of an amp I am building, Circuit boards came today and I started putting it together.   Most of the SMD parts are populated, the pic showing most of the through...

My Father in law dug out a box of brand new tubes that he saved from the trash bin years ago when he was in the military. Said I could have as many as i want.   I am not sure if any of these are suitable for an amp, but i thought i would post the part numbers and see if any of the tube gurus...

Hi, head fi has been a huge help to me over the past couple of years, and I am better off for it. I first started my journey all alone and thought I was doing good with my old iPod touch 2G and a set of shure 310's. Then I found Head-fi, I upgraded to some westone UM3X's, and a mini3 amp...

I had a 4GB Clip+ with an 8G memory card in it that I had RockBox installed on. It was one of my avorate players. But I plugged it into a car USB adapter to charge the other day, and now it is dead. I disassebled it, and the battery is at full charge (4.2v) but the clip is just dead, wont power...

Last year I built a Millett minimax as a gift for mt step mom who is loosing her eye sight and loves listening to music. I did not have a chance to really listen to it, and when I did it was through a crappy set of sonys that I used for setting it up ( cause i didnt care if i blew them up, a "DJ...

as the title states, I cannot find the right file to allow the rockbox installer program to install rockbox.   According to the web page, i need:   Clip +: An original firmware (OF), the bootloader, the normal Rockbox build.   I created a folder on my destop named "rbinstall" and...

working on a portable amp, I could use the standard SOT-32 stuff, but it makes it real tight. I am wondering ig there are any SMD (SOT-223 or SOT-89 etc) that are comprable to the SOT-32 stuff. Heat sinking should not be a big deal, as they will not be biased much.

I live in a small town in western Colorado, so test driving headphones is pretty difficult. I had some spare time last week, so I walked into the local box store with my sony X and mini3 to try out the few headphones they had.   the reason I stopped by was a new pair of sennheiser's they...

I'm designing a board to fit a small case, roughlt the size of my touch and 19mm thick. Of the dozens of amp circuits out there I have settled on one that i hope will give the best performance, it is basically a 3 channell active ground opamp(voltage gain) to a buffer(current gain), with the...

If you could design the ultimate personal media player (UMP?), what features would it have? Size? UI? Chipset(s)? inputs? Outputs? features?   I have 3 players now, a sonyX, clip+, and a 2Gtouch.   Outside of the hifiman HM-801, (witch is pushing it for portable) seems most...

I have a few boards made up that basically are redesigned mini3's. I wanted to play around with op-amps on them and am looking for advice. As they are SMD, rolling will be difficult, so I am seeking advice for a good combo of a dual SOIC amp for power and a complimentary ground amp. Thus...

I wanted to build a powerfull yet small amp to go with My Clip+. What I wanted was a digital POT, Lithium ion battery and enough oomph to drive a set of full sized cans... So what I ended up with was this, its powered by a 7.4v (8.4 on a full charge) 430ma battery, uses a DS 1802 Digital...

Just getting started building an op-amp based headphone amp. Did a bit of research on what resistors are best, and I came up with a lot of info ( albeit from years ago.... ) on through hole resistors, but not a whole lot of info on SMT style. The board I have disigned ( lots of hours to...

I am looking at building a verry small op-amp based amp to compliment my clip. It will be powered by a 7.2v (possibly a 10.8v) Li-Po battery. To save space I was thinking of using SMD Tantillium caps on the power rails, as well as the V+/V- (using a TLE2426CLP rail splitter). I was...

Fisrt off I know these are not in the same league, The UMX being a triple driver and the SHURE being a single "microspeaker". But they are close in price. I paid roughly $300 for each. The Westones absolutelly BLOW the shures away.by that i mean I now feel supreemly foolish for ever...

Hi to all. I am a bit of a newbie here and as such my first attempt at getting a good quality listening expieriance involved a few trips to the local box store and a bunch of waisted $$$. As most of my listening is not at home I naturaly went for a portable set up, figuring I would spring for...

I mean custom.... Hi to all. I am in the process of building an amp based on the mini3 ( I love my mini.....) I am designing it to use the high performance chipset with the following mods: 1, a 14.4 volt 450ma battery pack ( regulated down to 12v ) 2, an 1820 digital POT for volume...

Well, After much deliberation I finally did it. I love My 2G touch for its UI, but was never blown away by the SQ. Spent quite a lot of time here trying to figure out what was the best sounding PMP around, I narrowed it down to the sony X or Cowon S9, but there apears to be quite a lot of X...

Hi, So I have done some research and i have a general idea of what cans i want but....... I figure it bast to ask the experts befor I drop the hammer Looking to by My first set of cans, budget is ~$300 or so As this is My first set, I want a can that is generally well respected. My...

Hi. I am a new comer to the wonderfull world of preimium audio, so bear with me... My current gear is fairly low tier, I have a 2gen ipod touch, and my first upgrade was a set of sure 310's, nice improvement there. Then I desided to get an amp to power a good set of (still not purchased)...

I am a newb, but I am in the process of putting together (what i think will be) a killer portable set-up. I have just ordered an RSA P-51 mustang, and am planning on ordering a set of JH-13's before to long. this brings me to my source. I currently own a 32g Ipod touch 2g- and a 32g ZEN...

I'm a complete newb, so bear with me.... I've read through the forum quite a bit as time permits, I love it. I have been trying to research as much as i can so that i can avoid spending tons of money in the never ending "upgrade" spiral and buy the "good stuff" or at least "good enough"...
