Player for Westone 4 - make soundstage concert hall

The iPod classic is very good, especially when it is amped (LOD's aren't too expensive).

LOD stands for Line-out dock. It's a small cable that plugs into the dock connector and gives you a clean line-out signal. I found a surprising improvement with a Fiio E5 and my UM3X. However, if you really want soundstage, you will probably need full size headphones.

I found that the E5 improved the details in the highs and upper midrange and also improved the sound quality at lower volumes. It also has less hiss than the iPod's headphone jack, for some reason. YMMV, but I personally feel that the E5 is actually a pretty good amp and people don't give it enough credit due to the low price tag. It also pairs very well with the Sansa Clip+

If that's the case, get the FiiO E7 or the CMOYbb from JDS Labs on ebay, two amps that are much better than the E5, and don't cost much more. The E7 can be found for $80 (and it has a DAC) and the JDS Labs' Cmoy is like $60. The E5 is not going to improve the W4s, nor make its soundstage sound more like a concert hall. In fact, the E7 or CMOY probabably won't either, but the CMOY has very good synergy with the W4s, I had one once (but got a more expensive Leckerton UHA-4, which is like $199 now). Do not get the E5, you will be disappointed.

There is another FiiO amp, the E11, coming out soon, that is supposed to be very good for the money, but no DAC. Under $70 I think. There is a thread on it. May be best to wait and get that. FiiO's E5 was really their entry level amp, and it's really just a bass boost, and not great at that. The E11 may be just what you need.

there is an ipod/phone app called 3D music pro

it not only has a "3d" effect that may do what you want, but it also has 3 other effects options:

studio

concert hall

stadium

the effects are a bit over the top if you ask me, but one of them may suit you.

its only 3 bucks
