I don't know anything about these services. (Sorry to reply without directly answering your question.)Have you looked for a non-remastered copy? I have a CD copy of Abbey Road, but I don't have it with me, and I don't know if it was remastered.
Except for a rare Japanese 'Abbey Road', all Beatles catalog CDs are from the same CD mastering...there have been no 'remasters' since they were first released.And not everyone thinks they all sound bad.
'remasters' - exactly!Not to be pedantic, but all Beatles CDs are remastered.
p.s. Some of the services no-noise their stuff to death. I'm looking for a service that will keep the recording's fidelity, especially because it is a MoFi release
Yet, It's disappointing that nobody has released any audiophile CDs of the Beatles (at least that I know of).
Remember you are talking about 1960s recordings despite the utmost care. You can only go so far before there really is no audible difference due to limitations of equipment of the recording era.
