here comes Vinnie's mods : Please change this "Fragile-2,5mm plug" for a serious Mini-XLR, add a real line-out, and.... some more RWA black magic !
You want a line out? To feed to a portable headphone amp? The AK240 is big enough! And for $2400, it better have a great amp in there already. Otherwise, modded AK100 and AK120
feeding an external amp will probably be better. I just don't imagine something as good (and powerful) as a RSA R71B is going to be in there. There isn't enough space for that kind of
circuit.
My guess (just a guess at this point) is that the AK240 will drive IEMs just fine, but won't have much more power compared to the AK120 for pushing something like an LCD-3. Not even close to the power of something like the SR71B, or the ALO International.
I think the output voltage spec of the AK240 was already posted, and if I remember correctly, was not more than 1V more than the AK120.
Having said all of this, when the AK240 is on the market, I'd like to take a good look at it and see what it can do, and what can be done with it. All we can
do is speculate at this point about it, how it sounds, how good the interface is, etc. It could be a game changer, or it could end up being something that
justifies buying the AK120
