Funny thing is...with the SR80e I felt like there was a bigger difference then with the PS500e. No idea why though.
With both I do hear a difference in general, and like I said I was going to keep them...but I can't say that the difference was a $300 difference.
I'm also suspicious of what exactly is going on with the A200p controlling the iPhone's volume. Seems to me like maybe the software volume adjustment should be locked and the software EQ shouldn't work if the iPhone's internal DAC and Amp are being bypassed.
Of note...the sound quality was different when listening to the same music from my computer's digital out.
So that brings me to the question: Is the DAC in the A200p actually being used when paired with an iPhone? And if it is, why would the same music sound clearer when listening out of the computer's digital out? Why does the iPhone's Software EQ still work?
It's a puzzling device.
Yes it is.
