I came with the conclusion that a simple current buffer (JISBOS for my project) would be THE best way to make a simple cost-effective amp. I'm currently building a balanced JISBOS buffer/amp. One of the major reason for this build is : - only 1 simple buffer stage = only 1 source of...

@ akione (or anyone that could help) : I have a question about your balanced JISBOS, if you do connect the PSU's ground to the output grounds, where does the signal's output ground go (pin 1 of the XLR output) ?

Just changed the topic into a quick tutorial since I could not found a "complete" tutorial on the forum.

If you want to go balanced "cheap" I suggest you simply build a balanced buffer/driver (jsibos or as akione did using the IVY) since you will have a powerful source. Balanced buffer do have a gain of 2 that will be more than enough for headphones And you may still use that buffer as is or as...

I first had issues building it but thanks to Germania and FallenAngel I finally managed to build a "cheap" balanced cable for my HD 650. So here is a quick tutorial/sum up : Material You need : - Neutrik's XLR connectors male or female depending on your source's output (like this ...

or buy an used Opera ! - mine is great (though without DAC) : http://www.head-fi.org/forums/f42/fs...ldwide-336691/

To turn 4S into 4P the only way is to replace the whole cable which could be a solution for kmcdonou (you could then use the PtoS little adapter with your Move).

Here is a HD650 with Corda Opera. I've tried the following : - Project HeadBox (bad) - Heed CanAmp (fine but a bit too warm for the already warm HD650) - Corda Opera : GOOD ! I switch from the z to the Z output depending on the mood. z = analytic, in your head session, Z = laid back...
