I have been scouring this wonderful (and dangerous) place for the past many months to overwhelm myself with more information than I can digest. But I have just recently joined the HE-500 club, and I simply love this pair of cans. Currently my set up is the following:
iphone (flac) --> NuForce iDo --> HE-500
In general listen to jazz/vocal/acoustic, instrumental (piano, classical), and occasionally some pop. To me this setup already sounds very good, but I am wondering if the iDo is driving the HE-500 properly. I don't listen to my music loud, and have never need to go up to the upper end of the iDo's volume control.
One of my many noob question is, if amp is only needed if more gain is needed? Or if it's needed even in low volumes to properly drive the headphone (i.e. low-end/bass).
If amp is needed, I am also wondering if I should start with an entry level amp like the Magni or Asgard (would they be much different than the iDo)? Or just save the money and just live with the iDo for a few months/year and go straight to something like the Mjolnir? By the way, I am not fixed on Schiit gear, but it's just one of the company that constantly comes up in my search and have a product in different price point that is easy to use for reference.
