This is true from any source to any load. This is standard practice in professional recording and broadcasting facilities for this reason.
Interesting. At work I have Genelec 8020As driven by a USB DAC1, and I dropped the internal XLR jumpers way down so I could keep the volume on the 8020As at the max level. The reason I did this is that the volume pots on the speakers are not stepped, so it's a hassle to balance them each time I power on the Genelecs. Is it a mistake to drive them with their volume at max?
I also use my USB DAC1 with e500s, and like others can't get past 9:00... But I've not noticed any sort of channel imbalance. It would be nice to have more usable range, however.
Finally, when outputting from the USB DAC1's RCAs to my headphone amp (Triad Audio Lisa III XP), I can't get the volume control past 9:00 when driving my Senn HD650s. My e500s don't even stand a chance. There is no way to attenuate the RCA output, correct? I suppose I could have the gain on the head amp dropped down.
