I'm shameful... and I'll see myself out and brush up my graph confirmation skills now.  :p

Also, the measurement tool and compensation cannot be certain how accurate they are.  Impedance is universal though.

Your customs are more V shaped than my customs.:tongue_smile::etysmile: LOL

Hello Goodvibes,

 

I need to correct you on one thing: I didn't test the CT7's impedance or input requirement linearity. I quoted the manufacturer. It has been my standard for finding hiss in sources as it is very sensitive to hiss; there is no earphone I've used that is more sensitive to it. 

Apologies. I assumed that you measured it with an ohmmeter because it's not commonly given by makers. At least that one's easily repeatable. From experience, actual impedance at low frequencies is generally about 25-30% higher than measured resistance.

Point was to use drivers that that don't do that. There's plenty out there to choose from and not that difficult to have things made. It's never easy to make a good multi way device but starting with viable parameters helps. If you make the best IEM in the universe but only 1/2 the buyers can approximate it's true performance, is it really a great design? Most DAPs and even stationary headphone amps or consoles have 1 ohm or higher output impedance. I think a 2 ohm output impedance should be acceptable for a DAP.
