That is the correct wiring.

I like this idea, it oozes overkill.

Thats absolutely solid. Invaluable info, thanks Kevin.

Thanks Kevin and Birgir, I really appreciate your help with this. I've been digging around here and in the Headwize forums. I can't find a formula for the final output in the fourth stage. If a 2.1V LED yields ~ 4 x 5.5ma for 20 watts. How do I for example equate a 3.8V LED? I just don't want to crap shoot this... John

Practical vs theory I guess, I was dubious with the set-up, I can’t deny my ears though.

I shall, I don’t want to push her sky high, just enough to justify these big sinks. Well for starters I’m not using 1.2k resistors, I’m using 500R for the A1968 current source, I really should pay attention. In regards to increasing current I assume the 500R’s are to be replaced? Just after a little knowledge on how to derive mA values.

At a recent meet I had the opportunity to listen to these out of a Weiss 202 DAC, they sounded superb for closed phones. Edit, btw the above impression was straight after I had been listening to the T2 with the 007 and 009’s .

I’m going to do some experimenting with the bias current. My 400mm 3U Modushop heatsinks are running cold with the A1968’s . I assume the only change out is the 1.2k resistors for the current source? I don’t want to go too nuts, just enough for some get some heat happening. How to do I go about working this out?

I wondered where those BH boards went, they disappeared after a visit from wink. ..ok now I have to say this, Erwin (wink) is one of a kind. I think he's one of the most generous people I know, who happens to have one of the biggest headphone collections... And he lives close by, need I say more, just don't serve him instant coffee. Looks like a great project livewire, looking forward to seeing the updates.

I’m going second Dusty’s vote for Deadwood, just loved it.

Made my day.

Agreed. The combo is not optimum.
