Inna, this is stuff dreams are made of, it's called EE tape. If a person had a reel with a EE seting , he could record at the slow speed of 3 3/4 and get 7 1/2 quality of sound. That doubled the playback time without reducing quality of sound. This was long before I got into the high end, and playback time was our concern.
As it turns out, you don't need those EE settings, this tape will work on any reel. I'm listening to it on the 2 track Technics and what I'm hearing is truly unbelievable. ( A 2 track Otari will be even better) Holographic is an understatement, the musicians are here in the listening room.
This reel was not in a gold EE box, but as soon as I heard the first tune, I knew it was EE tape. War "All Day Music" was the first LP; it's hot fun in the summertime. "Let's go to the beach, play in the park, or roll in the grass long after dark". The year was 71 when such things, even for us, were on the good idea list. On this tape, each vocal or instrument is surrounded by air, decay time on any thing that rings is forever and the musicians are in the listening room.
Everyone whose heard EE tape wishes it would come back. I'm positive, no matter how good someone else's rig is, they wont get sound this good unless they got a reel and EE tape; think about it, the high end is the starting line, then you throw in a reel; that boosts it up a notch; next you add the EE tape, that puts it over the rim; I sure hope they bring it back.
Top notch gear is only half the story, good recording results require explicit planning and execution. "Watch power cords and interconnects, arrange so as not to create hum". Enjoy when it's time, but don't rush.
