I think all of the Giles Martin Remix's are better than the original, and I don't even listen to the old mixes. I listened to The White Album yesterday with headphone and you hear so much more. Today about a lot of years ago Sgt. Pepper was released. I listened to the Giles Remix on the way into work.
If you have a ton on vinyl, depending on how stored it, they may have thought its just to heavy to bother. I keep mine in crates. When I have to move them its a chore. Picking up a pre-amp is nothing, and most people keep guitars in cases and look its got a handle, so grab it an go.
