I have 106 hours on the Amphora now, and tonight I tried the Grado RS-1 again.

The Amphora is most definitely better with the RS-1 after some burn-in than it was out of the box. The iMod/Pvcaps/Mustang no longer has the slight lead that it held previously with RS-1. (this is still with the flats that I installed on the RS-1 back on the first day). With some pianos the Amphora is actually now ahead with the RS-1.

The goal is 200 hours of burn-in per KB. It will get charged tonight when it reaches 110 hours, then I'll continue burn-in tomorrow morning and maybe even see how long the battery lasts before it dies. I have not let it run more than about 24 hours before charging it, just to be sure it wouldn't die while I was out and about. I am doing much of the burn-in and listening with my Macbook > iBasso D10 optical > mini-RCA > Amphora, since the iMod doesn't last more than 14 hours on a charge while the D10 charges via USB and can stay topped off.

The sound signature and soundstage between these 2 sources is actually very similar when using the same lossless music (diana krall live in paris for example), with maybe about 1dB more output volume when I switch from the D10 to the iMod as source. I am not about to do a D10 vs iMod review, but the iMod is clearly above the quality of line out from a normal iPod. The D10 with native 24/96 files via optical does pull away by a small margin, but the iMod with Vcaps is pretty darn nice, especially with the Amphora.
