Metralla is right. Any vinyl pressing is going to be a DAA at best (digital recording, analog master, analog pressing) but more likely a DDA (digital recording, digital master, analog pressing) so you wouldn't really be getting anything special for your money, at least not insofar as "analog" recording is concerned.
However, I own both the commercial CD release and the XRCD release of Brothers, and I can tell you difference is amazing, as is the XRCD version of The Eagles Hell Freezes Over album.
