Right now I own a pair of Sennheiser HD 598. They sound great, but I despise the way they look, so I ordered a pair of AKG Q 701 which, from the pictures, look sexy as hell. If you want to comment on the sonic differences, be my guest. But this is about amping.
I know the 598s didn't need to be amped, but since I sometimes do audio work on my computer, I decided having a big, fat volume knob would be great for working with some lower volume recordings before I amp them up in the end. I originally bought the E7/E9 combo, and was so pleased with it I upgraded to an E17. Since then, I have also acquired an MF V-DAC II that I use for my serious DACing needs
Will the E9 be sufficient for amping the Q 701? I barely get the volume know to 10 o'clock before the 598s are too loud, so I imagine it will be OK, but just wanted to be sure. Also, I'll be attending a wedding in a few weeks. I'd like to be able to listen to music in my hotel room, but don't want to lug the E9 and V-DAC there. Will the E17 be sufficient to drive the Q 701s? My brother will be there and I'd like to impress him with the sound, since he thinks I'm crazy for spending so much money on headphones (he thinks his $50 Sonys are as good as it gets).
In the future, probably around Christmas, I will be looking to upgrade my headphone amp. I'd like to get a tube headphone amp, but am also considering the V-CAN to match with my V-DAC. Any other suggestions would be appreciated.
