They definitely are very cost effective. When I had the he6 I had the v200 which did not drive them well. I also had a Mjolnir which was much better but not quite there and then I bought a $150 or so speaker amp that drove them much better. I have heard them through some good speaker amps and they do sound better but at the cost of the speaker amp it really is a bargain I wouldn't want to use a speaker amp on any other headphone however.
