So they can spot if I missed a solder joint? I'll try in the morning I think it might be an issue with the LCBPS possibly, since it's both channels. Is it possible that low power would cause the sound to suck?

I've seen bad solder joints in photos before. It's more to do with seeing how everything's connected.

Not sure about low power. If the supplied current is not enough, I believe the LCBPS voltage would sag. Might be worth checking.

So I used my multimeter and established that FB has been shorted to GnD somehow. I checked my solders, none are touching at all. Both boards this is the issue, how should I go about trying to fix?

Moved, thanks all for your help!

Well I finally finished and cased up my amp, and it sounds great. Only gripe is the voltage gain isnt enough for anything other than low impedence cans. How would you recomend I change the gain? What resitor swap should I make?

Could this headphone amp be run off a +/- 9V DC supply? That is what I have available.


With SE input, could I drive balanced and unbalanced phones? If, so what would I need?

Yes.

It has balanced inputs, but can be used with SE input be tying -IN the GND. The outputs are only SE, however.

Hi there,
after asking in the wrong thread (Ventus instead of Ventus EZ) I can't find any manual so yes, I've never read it.
I'm used to find all what I ever needed for my Placid, BII, Legato... but not here, seems some links are down at TPA website. Any build guidance, such as to know how to feed it (input Z, passive pot from line option, DC offset @ output and case of DC feed, when the output coil is needed or not...). Found the info on the optional CC1 cap but that's it.
Any tips welcome, got 2 boards in hands after a cheap and quick auction winning bid and wanted to build a stand-alone head amp. Planned UltraBib supply therefore I need also the current drawn.
I just request infos I do not have, if not I'm okay with no answer so please stay cool no need for angry "ask Google".
Thanks and keep cool guys!
