The emotiva is 160 now at Amazon I am sure it a winter sale.
I am currently listening to my he-500 on the nfb 11.32 it definetly is loud enough for me. I have had the emotiva before but regretably sold it. I am debating on keeping the set up like that and getting another closed headphone or getting the emotiva again. I like how it sounds but I want it to be a little more smooth and with stronger bass impact. I don't know if the emotiva will do that but after revisiting this thread and hearing that it needs atleast 5wts to sound its best it seems like a no brainer.
The guy I sold my emotiva to told me it was nice but didn't help the bass out that much.
