Headphone Amp Question

For more information than you can consume regarding headphone gear I'd suggest headfi.org. While researching your question I did discover this post from a headfi member.
"The B&W P7 is designed to work with portable devices, and as such, does not need an amp to sound its best. Unless you really want one, consider not splurging on mid-tier gear for now and focus on something cheaper, such as the Schiit Magni 2 (amp) / Modi 2 (DAC) stack. That will more than drive the P7 to their full potential and still be future-proof for most of your future headphone purchases."

My friend Robert, who I refer to as "Mr. Golden Ears," has the Grado battery operated headphone amp. He loves it in spite of the fact that it eats batteries. He says its very tube like in overall sound. They can be picked up used on Ebay for around $350.00.

Scott,have a look at my second system.Then go grab a Schiit Audio(yep just like it sounds) Vali Hybrid amp.The all tube amps(except the $600.00+ Woo 6)aren't good with low impedance cans.Hybrids are juuuusssttt right!Schiit Audio is 100% American Made!Running off the PA will work fine.

Hi All, Thanks for the responses. I have some homework to do!
