lol I've had bigger portable rigs
Got my mad dogs today from a fellow head-fier. Plugged into my magni. Still encountering some electrical issues with static/usb ground loops trying to eliminate them though. Wow these things are great. I am coming from D2000's and these have more detail, lush mid range, instrument separation and much better mid-bass. The super low rumble isnt quite the same but I can live with that. It is very comfortable if not a little tight. I also tried plugging into my old Nikko NR-315 receiver, about 15wpc. Sounded great. Didn't do a lot of A/Bing there. I will say these things need a ton of power. Magni has a ton of gain and I am up to around 11 oclock with them compared to 830 with D2000.
I will try them straight from my E7 and see just how much a difference there is for everyone asking if portables can adequately drive them.
edit: e7 can drive them OK. Sound lifeless compared to with magni. Bass lacking.
You can fit that in your pockets? I'm not sure whether I should be impressed, frightened, or envious...
Oh good lord... What's the point of all that again?
I don't think those are as wide as the O2 though...
