As Rja said Music Direct has started reissuing certain titles on gold cd under the Mobile Fidelity label within about the last year. You can see the titles on their web site.
You can buy one or two of these to see if they are worth the extra money to you.
As for older MF gold cds some may still be the best sounding, but cd sound quality is improving pretty quickly so a recent non MF remaster may sound better.
There are also Deluxe Edition and Legacy Edition aluminum cds that are remastered and are usually expanded 2 cd sets. These reissues usually offer live material or alternate takes on the second cd.
So I wouldn't spend a lot of money to get an older MF gold cd but if you can get one for a reasonable price check it out and see what you think.
