Honestly just the 280s then..and no amp. You won't notice the difference and you can get the 280s for cheap locally ( I thought).

Why with no amp?

 

[WillD]

It wouldn't help enough to justify the cost.

I took a closer look at my stereo's "4-Channel High Power Amplifier" and found this:

Would that work with the A500's audio plug? When I measured it, it was about 3/8 inches long.

????

Is that a 1/4" or a 1/8"?

I can't believe this went on for 9 pages. Just decide already!!

To me that looks like a 1/4" jack (the big kind).

 

[Azure]

Do the A500s come with a 1/4" jack? So, then I don't need an amp and can just use that jack on my stereo amp (Have my PS2's audio go directly into my stereo's receiver)?

About a source not being able to power headphones, what determines this? The impedance? Frequency range? Sensitivity?

A500s:
-Frequency Range: 5-30,000Hz
-Impedance: 64
-Sensitivity: 100dB

The sources I'm considering getting are the following:
iRiver iFP-795:
-Frequency Range: 20-20,000Hz
-Impedance: 32
-Sensitivity: 107dB

Apple iPod Mini
-Frequency Range: 20-20,000Hz
-Impedance: 32
-Sensitivity: 100dB? (Can someone find out for me?)

Creative Zen Micro
-Frequency Range: 20-20,000Hz
-Impedance: 32
-Sensitivity: 98dB

Creative Zen Xtra
-Frequency Rance: 20-20,000Hz
-Impedance: 32
-Sensitivity: 111dB

So, based on the above, which would be the best choice for the best sound quality for the A500s? I noticed that all of them had half of the A500's impedance, is this bad? What mp3 player has 64 impedance? What about the frequency range of all these sources? They seem to have the frequency range of you're everyday $8 headphones, how would the A500s handle this low frequency range?

 

[WillD]

The A500s have a 1/4" adapter, so that would work.

None of them would be better for the a500 than the other.

 

[Azure]

Do the A500s also come with a mini 1/8" adapter? Also, is it okay to use headphone cable extenders without reducing sound quality (Apparently cables make a difference in sound quality)? Anything I should know about when picking a headphone extension cable?

So, you're saying there would be absolutely no difference in sound quality among the 4 mp3 players I mentioned with an unamped pair of A500s?

 

[WillD]

The A500s are 1/8" already WITHOUT the adapter.

And no, what I am saying is that not one would be better for the A500s in particular. One of the players probably has better SQ period, but not because of the headphones they are being used with. At this point..just get the player that you want.

 

[Azure]

What about headphones extension cables? Anything I should know about them (The whole deal with how audio cables make a difference in sound quality)? Any recommended ones?

 

[Kenny12]

i would get the iriver cause i heard they have the best sq
