um, no.... preamp out IS "line-level." and so are source outputs--they are all "line-level." doesn't mean anything. the question is whether the signal is loud enough for the perreaux... and yes, you are right, most CD players are quite hot enough. but no, headphone amps are not necessarily "made" for direct source input... but they do mostly work fine straight from the source as you have said.
and if you're wondering why i don't hookup my amps directly to the source... well, it has mostly to do with aesthetics and the working environment, but also my CD players has such a hot output that it fries many of the headamps out there. i even have to use attenuators going into my preamp. and it's easier to use the preamp as a control device--also, i like having fun with tube preamps.
anyway... believe me, i know how to wire stuff up. i don't think anyone on this board has a more complicated home-based system than me...
but from your responses, i take it no one has gain problems from this headamp then. no biggie... it probably has more to do with my own preamp, which is a bit quirky.
|The best way to drive a headphone amp is to tap into the signal at the earliest possible point after the source selector. This is usually the tape outputs of a preamp or passive unit.
i disagree. it is only practical to do that in a very simple system. yes, you are right, technically what you say about the function of a preamp is correct... but in reality, that's not what you use preamps for: they provide source selection, and volume control, basically. and almost everything sounds better straight from the source, but that's not how you necessarily should connect things. you usually do need some sort of volume control and source selection, hence the consumer preamp. here i use a mixing board though... and a separate audiophile tube preamp for monitor control--PURELY for fun.
