Hi --- I'm new here and just ran across this project last week. If a BAL-SE board is still available (the group buy Wiki seems to indicate that it is), I'd like to get one.

Thanks!

i'm wondering what the buffer heatsinks are there for if you wont be using them? also there is nowhere near enough ground pour, the ground and power traces i'm not sure they are thick enough either. without more info its hard to make further comment

Still waiting for it to arrive in the mail.

I've been enjoying the first version though.

As soon as I receive that magical PCB in the mail mine will be built faster than you can reply "cool"... and I'm sure OPC knows we're all looking forward to it...

Default Excuses, excuses!

>>Still waiting for it to arrive in the mail . . .

Can you believe these lame excuses, qusp? I had mine built before opc even shipped it and had pix to satisfy your demands :-)

I must say the BAL-BAL is STUNNINGLY good. With HD-600s it is noticeably more detailed than the double sided pcb with LME49710s at the front end. I am not allowing myself to imagine how it might be improved with better cans.

You have given us all a great gift, Owen. Thank you. And thank you, qusp, for noticing that the qmini might not be adequate. It was not. I have had time to switch it in and out, and with both preamps, and it bogs down with four buffers.

I'm planning to take the time for a build during the holidays.
Unfortunately that's not entirely under my control, though. Family matters.

I managed to modify my beloved AKG K501 using Mogami star quad cable and Neutrik Plugs already, though. So I'm prepared.

Looking forward to the build, and got a question.

Mine's the SE-SE version. Is it ok to put a vol pot at the inputs, and if so what would be the optimal impedance for it?

Thanks!

depends on what you are driving it with, but yes sure, a 10-25k pot would be fine i think as a starting point.
