Led zeppelin is my favorite rock band of all times. I was in high school when the bulk of their albums came out. Me and 4 other friends did what we thought was the first ever air guitar gig in front of a large crowd. We had professional band speakers that filled a high school gym and in front of 3 different high schools we performedan air guitar of Led Zeppelins "How Many More Times". Drums, vocals, guitars, the works. We practiced for weeks before putting on the show at our high school assembly. By the end of the song, the crowd was clapping along with the song. It was crazy...... So I know where you are coming from.
Fast forward to 2019. Sold by K-horn knock offs and decided to get serious. All new equipment. Pre amp, power amp, dirac correction, streamer all wired into a lovely set of Legacy Audio Focus XD's. Those alone are around 16k. I have a fabulous system and with that comes critical listening and a system that has no mercy for lousy recordings. Unfortunately, Led Zeppelin falls into that category. I never listen to any of it on this system. Sounds awful and I wound never embarrass myself by waltzing into a high end shop and ask to listen to Led Zeppelin..... and yes, it is heartbreaking as the performances are forever stuck in lousy recording pergatory. What a loss. To bad Jimmy page didn't have enough sense to have demanded a recording engineer that knew what the hell he was doing. So, you are not missing something. When you get your new speakers, put on "Dancing Days" then after that, put on "Creep" by Radio Head or Def Leppard "Back in Black" and you will immediately understand why the greatest rock band of all times f'ing blew it!
