DW: How do your Grado's sound with the empeg? Just adequate volume level, or will they go really loud?

From what I've read on some of these message boards, it sounds like there's no ideal headphone for low output devices. The Grados seem to be greatly admired for their involving sound and efficency yet they're ugly as hell, leak exessive amounts of sound, and many feel not very comfortable. The Sennhiesers are not at all efficent yet they look great, are very comfortable, and have a laid back sound that's ideal for taming the somewhat harsh sound of the RioVolt. The Sonys have everything just right, except many seem to think the bass is a bit too heavy and highs rather bright. I really dislike the boomy bass that so many headphones I've heard have.

I think the Sennhieser 495's might be my best bet, but their efficency is a real problem. Sigh. I think I may have to go with the Grados. My nearest Grado dealer is 100 miles away so I've yet to hear them though.
