FiiO E1 + E7 (speculation-no-more) *now guest-starring: E9 - Page 9

Those are pretty much copied from here. So far most of the info regarding E1 and E7 is coming from this thread.

Now I know E1 is supposed to hit the market by now, but given that Apple just released a few new models, my guess is FiiO is trying to make sure there won't be any incompatibility issue before sending the amp out.

Just a small update: I'll be receiving an engineering sample of E1 in a week or so and perhaps a few of new FiiO accessories for testing as well (but not the E7, which is still on schedule for December release as I was told).

Also, the E1's ETA is currently on October.

In case you can't wait, here is the stock picture of E1.

Well, E1 should arrive this week assuming no delay on the postal service.

As far as improvement goes, don't expect any giant killer (*being realistic here). I think Raz @ MP4 Nation has commented that the performance closely resemble that of E5. If it is so, then I guess it will worth the price you'll pay (<$30), but it probably won't be a match for a well built cmoy or anything better that's going to cost several times more money. For the least, I think my Nano 4 can benefit from the E1 since I find the headphone-out to be fairly average - of course that's assuming the headphone will benefit from amping as well. I don't want to put too much speculation for now, so I'll wait till I tested the E1 first before passing any real judgment.

For what I know, there will be play/pause, next/back buttons as well as volume control in the final production model. Will need to confirm later on.

I don't think there is a bass boost switch on E1.
