So, I'm liking my V3 with 6N1P-EB's a lot. Especially with my 250 Ohm DT-990 Pro's. I do have my doubts about my 80 Ohm DT-770's though. They are capable of really low bass and are often suggested for the bassheads. With my X-Can V3 they seem to lack some bass. Not that much but enough to make me wonder 'where did the massive bass sound go?'. Could it be that the V3 works better with higher impedance phones? I could just build a small impedance adapter for my DT-770's and try it but I would like to start on this with a little more founding facts and if so, which impedance would be good to try? I don't have any really low resistors laying around. I do have some 680 Ohm resitors around, which I could you use. Two parallel would give me 340 + 80 (the driver's impedance) = 420 Ohm (right?). This might be too much. So if anybody can shed some light on how I could approach this the proper way, I would really appreciate it.

Btw. I KNOW that putting some resistors in-line isn't the same as some real high impedance phones. On a second thought, could it be that the stock PSU isn't providing enough current to drive the 80 Ohm phones properly?

Ok, it seems I just have to try it out then and see what happens... ;D

Tried it yet?
I am planning on something similar for my Stealth, which does not like low impedance phones.

No Kees, not yet. I'm still planning to try it though. Haven't had the time to go and buy the needed resistors and connectors. Unfortunately there's only one store around here where I can get this stuff. I used to be so much better around here (Rotterdam).
On a side note: Recently the behaviour of my DT-770's changed for the good. It's almost like the lack of bass was a temporarely drawback of burn-in. They start to sound like I expected them to sound.
But, like I said, I'm still going to try it but I haven't figured out the best value for the resistors. I would have loved a more scientific approach to which values to use but since I can't find anything which gives me insight in how to calculate those values I guess I'm stuck with just trying. I think I'm going to try different values, like 60, 80, 120, 200 Ohm. It will be pretty hard to determine which value will be best because of the unavoidable difference in output volume.
Cheers,
Matthieu

I asked around and was told that 120 ohm (or there about) should do the trick.
