aaron-xp 0 Report post Posted September 7, 2006 Pardon me for asking, But what would amping a headphone out do to benefit the overall sound. If an already bad source (which has gone through the built in amp) is being "re-amped", wouldn't that just amplify the distortions? If that is so, is the only benefit of amping a headphone out to drive those power-hungry cans? So does it mean that lower impedence 'phones don't need headphone out amping? Sorry for all those questions... Am really new to the whole ampifer thing. Share this post Link to post Share on other sites

If an already bad source (which has gone through the built in amp) is being "re-amped", wouldn't that just amplify the distortions? It won't do much good. Most built in amp would corrupt the sound. There is benefit but very little. If that is so, is the only benefit of amping a headphone out to drive those power-hungry cans? So does it mean that lower impedence 'phones don't need headphone out amping? Yes, for power hungry cans. Depends on different cans, sometimes low impedence cans are power hungry and needs an amp.

theory_87 0 Report post Posted September 7, 2006 X5 and Lineout doesn't match. There's audible lower bass falloff if I remember right. You'd be better off amping from the headphone out, or adding a resistor inbetween the lineout and interconnect. EDIT: Never mind, found the image (Take note that this is without load) do you have for ipod nano lineout, headphone out and ipod 5g lineout and headphone out?

Zephyron 0 Report post Posted September 7, 2006 (edited) Ask and you'll recieve (as long as I've seen it being done or have done it myself, note that these 5G and X5 results were not tabulated by me) iAudio X5 VS iPod 5G volume matched. Both of these are taken from the HPO (Note that the fall off at the end of the lower bass spectrum did NOT reach 3dB, hence its supposedly unpercievable(sp?)). In short, when zoomed out, this graph's pretty flat. Oh yes BTW, I found the graph where amping the Lineout with a 32Ohm resistor is added in-between. Didn't do much help... Instead it got worse... I think a higher resistance MAYBE needed: EDIT: Add: If anyone's willing to lend me the Nano or anything else to test out, I'll be willing to help and test them out tho Edited September 7, 2006 by Zephyron Share this post Link to post Share on other sites
yotiao 0 Report post Posted September 7, 2006 I used the X5L last time, the stock docking line out sucked, but the headphone out very good. Share this post Link to post Share on other sites
Zephyron 0 Report post Posted September 7, 2006 Nope, just saying that he can get 'better' sound using the same DAP by using alternative means. I didn't say the X5 was bad now did I? Share this post Link to post Share on other sites

aegisofrime 0 Report post Posted September 7, 2006 Interesting topic. Incidentally, I have a friend who's Creative DAP is dying (big surprise there) and might be shopping for a DAP. He wants to get a CLT-720 but I keep telling him that he might as well get a X5L; beats carrying around all those CDs and swapping them around where he could just loseless the whole bunch.
