On the surface it does seem odd that you would be (further) amplifying an all ready amplified signal. I suppose if it were the only way, and as others have said, the source is a clean one it can be better, but...
My iPod all ready provides enough ooomph to drive my Grados or Etymotics to a level that is painfully loud. How ever, the caveat being that I do not desire "loud", rather I want an authoritative reproduction of the music I enjoy.
I am currently having a bit o' difficulty accessing my 60 gig 'Pod's line-out, but should I ever be successful
, I will gladly let you and any one else interested, know what I think of it. Should there be any sonic improvement I will most assuredly be purchasing a dedicated amp.
I plan on playing the iPod (with a real line-out) through my garage stereo and my Music Hall RDR-1 radio. At the moment, I am only able to use the headphone jack to out put the signal and as such I am required to turn the volume on the 'Pod all the way up just to hear it.
Admittedly, I am no audiophile (tho' I aspire to be
), but I should think I could detect a difference in the quality of what I am listening to. As an example, my son and I went to a very nice audio shoppe yesterday and he listened to some excellent "budget" equipment (NAD). He was well aware of the difference in sound between good equipment and the little cheapo all-in-one stereo that he has had for a couple of years.
So much so, that he is willing to work to earn the money to buy his own "real stereo" (his words). The difference is detectable. I just hope my own aged ears can discern it.
