Sorry to inform you that if you haven’t heard these discs, you haven’t really heard the albums. I had the Dolby quad reels, and they simply don’t compare at all. I’m kind of amazed that I once thought 7-1/2 ips reels from analog dubs sounded great.I heard those four albums by the Doobies, over and over again in the seventies, in quad, and today I don't have any more desire to hear them. I don't know if l will ever feel differently in the future.
I’m really looking forward to more WEA quad masters on Blu-Ray. I‘ve loved Lightfoot Sundown quad for 42 years, but the quad reel just sounds old and tired to me. I know the master would kick ass and sound fresh again.
