  1. Diy Lod Full Step By Step Do It Yourself Guide With Pictures

    Originally contributed by Parrots, thanks!   I remember when i first started making my own line out docks, even though there are some instruction here how to do it, I thought it could be a little clearer. I had to make a fellow head fi'er a LOD I promised him awhile ago at no charge so decided I would take some pictures and post a short guide here. What you need: Soldering iron Solder (with added flux) I find mundorf silver/gold to be the best. Wire (your choice) 3.5mm Jack plug...

  4. How To Create A Link To A Refererce Inside A Document

    What you are reading is how to add an "anchor" to a post or wiki. There appears to be support in the "Link" tool for linking to an anchor but I couldn't find an easy way to insert an anchor into the document. A workaround for now is to insert an anchor using the "source" editor. The HTML anchor tag requires two fields. The first field is an identifier (id="user_unique_anchor_name") and the second field ("My text label") is a label describing the reference. The format of an identifier...
  5. Impedance Matching

      Quote:   Now, my question would be whether it is common practice for manufacturers to include a buffer on headphone amps before the gain section.  Is it always done, or is it sometimes done and sometimes not?  Could this be why some amps receive wildly different reviews, or is "synergy" and "taste" still the most likely culprit?     This is an interesting question, but requires a little thought about the nature of impedence and AC signals.   Unfortunately, it's not...
  6. Ibasso Balanced Portable System

    Developing a portable listening system that has the ability to provide balanced and single ended audio to headphones.  The purpose for this setup is to have a system that "approaches" desktop performance and provides a learning playground.   Using a portable DAC that has balanced output to a portable amplifier that has both balanced and singled ended inputs and outputs.  I am starting out with the iBasso system and will expand this as new equipment is purchased.  The first iteration with be...

  8. Hi End Cables

    Audio Cables are quite an interesting topic. Their performance is based on the following:    1.) Physical build stress handling capability, ever wonder why cheap cables introduce noise when they are twisted and turned?   Mainly because the fibers inside them are constantly coming in and out of contact which changes the inductive reactantance in them to make the cable suddenly shift its characteristics and introduce noise due to the change. Good cables do not have this problem as...
  9. Cowon J3 Info

    Hello Algelopsaro!   Your observation is very relevant and, in a sense, correct. Here I make some observations: 1 - Strength and weight of sound - I do not know your PC, but it is quite natural that the sound from your PC (even an onboard sound card) has more weight and life than the Cowon J3, because of his higher output power . On the other hand, you lose a large part of the definition that J3 is capable of delivering; 2 - Brainwavz M1 - This is an amazing headphone, that...
  10. Glossary Of Terms

    This is a work in progress. Please help us by fixing any glaring errors and writing useful and easy to understand definitions.   ACSS - An acronym for  "Audio-gd Current Signal System" which is a variation on the CAST (Current Audio Signal Transmission) circuit design developed by electronics manufacturer Krell and other similar concepts.  It is a means of coupling individual gain stages (either within a component or between two ACSS-connected components), which minimizes the audible...

  12. Headphone Impedance

      What is Headphone Impedance?   Headphone Impedance is the electrical characteristic of the headphone voice coil and magnetic field coupling of the voice coil & magnet inside the headphone. Impedance is an electrical unit which expresses the combined Resistance, Inductance and Capacitance of the headphone's voice coil. In terms of matching to an amplifier, the headphone impedance is the "Load Impedance". An amplifier drives a headphone with voltage, the current drawn by the...

  15. List Of Diy Headphone Amps

    I just had a thought: we need a list of current do-it-yourself headphone amplifiers. So here it is. I'll be updating when someone alerts me to new amps or amps that I have missed. Now, since there is a very large amount of circuit designs available, I'll only be listing available kits and PCB (if you want a circuit design only, you should check headwize).   And what do you know? I just found a brand new design that came up yesterday (31/01/2011)!   Available as a kit (and sometimes...
