Enjoy!!!!! They do respond well to my Melos SHA1 headphone amp, so you should should enjoy them with your toob.
I listen to them everyday, err, every night! Because I am a Maggie man I find these headphone much to my liking!!!!! Also, late night listening does not leave me wanting for much when compared to what I would enjoy from my speaker based system. Can they be improved upon, sure! But they certainly are more satisfying than any other headphone that I have had. I hope you find them just as enjoyable.
