Could the player being used be sending a slightly different sound signature? Is it the same player, player version, player settings and/or EQ? Or maybe the two devices output different formats, bit rates, resolution?
Also don't the Android and iPhone devices have two different inputs? Android plugs into the MicroUSB port while iOS devices plug into the USB-A port? That's what I understand (I don't yet have a HA-2 or HA-2 SE.
What smartphone are you using?
In answer to your second paragraph you are correct. I am not sure what you mean in your first paragraph though?
I tried the Teac with the iPhone 8+ late last night just while the Oppo was charging. Dear oh dear, I did NOT expect the much less expensive Teac to sound anywhere near as decent as the Oppo. Wrong. That Teac is simply superb. No need for the base boost and the warmth of sound is staggering, not boomey but crystal clear and so informative. Different sound production to the Oppo that tends to be more analytical even though again simply superb. After 12 months searching for the one set up I now have two! So typical eh.
Neither the Teac nor the Oppo work via OTG with the Note, The note tries to charge both the DAC's? I am waiting for the cable to fix this situation.
