I did a comparison with my Led Zep II Mobile Fidelity LP with the remastered CD and there was A Whole Lotta difference! I also compared my Classic Records Led Zep IV LP with the remastered CD and again the LP sounded superior to the remaster. Guitars sounded totally different, cymbals decay were much more prevalent on the LP as did Robert's voice. Unless the remastered 180g LP's sound different to the remastered series CD's from the very same source I'd be surprised.
