Would they be worse if it wasn't modded?
Would they be worse if it wasn't modded?
It's personal preference what is better or worse, but they will definitely be different. To hear the 4a.i as they're designed to sound, you'd need the mod or an amp to prevent the influence of the AK100's output impedance.
Some people are finding benefits from that influence though (e.g. Spkrs01 preferred 335DW with just AK100, no amp) so it is very much personal.
Isn't the 4ai impedance about the same as the AK100 output impedance?
I had a listen with my 3A and the impedance is the same as the 4ai. It was pretty damn good. I didn't hear any distortion. I think as long as your impedance matches you're fine. When I get one I will definitely not be modding at all.
I see. Might not be the right dap for me then. Shame because it's a nice looking dap with a good amount of onboard storage.
Can CraftyClown or someone else please explain to me that rule of thumb? Why is that so?
I started reading this very technical paper on impedance. All I understood from it, was that if the output impedance is too high, energy from the source will come back around and cause reflections or echoes.
I didn't hear echoes or reflections through the 3A. So I guess it's all good?
I just read it. So it really depends on how flat the impedance to frequency curve of the headphones/earphones are. The flatter it is, the less important impedance matching is. For the dap to be versatile it should have less output impedance so maximum amount of voltage can power the headphones without inefficiency occurring.
No where in the article was there a rule of thumb that had a multiplication of 8.
