Just to be clear John, did you have the stock L-cush on your GH-1, when you compared them to the GS1000e?
I agree, not all battery powered headphone amps are meant to be portable. I'm pretty sure that quietness was the main reason why Joseph Grado chose to include battery power, for his HPA-1 and 2, wasn't portability.
Like you, I use my RA1 in house too. My BSG C-Moy mint tin, is the amp I use for portability.
For some reason, I'm sure you'll be proud of me, if I tell you that I use it with my RA1 with my RS1, and my HPA-2 with my HP-2.
For my comparison, I had the G Cush pads on the GH-1.
