Reel to Reel Tape, once you hear it, oh man what a difference.
The console I inherited had a 2 Track Stereo Viking (Telex) Deck in a drawer, and my uncle had many Classical and Opera 2 Track Stereo tapes. Amazing, my best sounding content, but Classical and Opera was not for me.
My era’s music: 4 track, auto reverse, I went thru Teac’s line ... finally settling on their X2000R auto reverse, 6 heads. I’ve got two of them, and one prior X1000r needing tension adjustment which I can do myself. It’s my son’s, I gave it to him, but history repeats: he knows how good the 60’s music is, but for him .....
I bought about 500 4 track tapes on eBay many years ago, shipping cost more than the tapes back then; sold about 150 of them.
I recently gave my uncle's 2 track tapes to a friend I met here who has two Otari 2 track stereo decks. They sound awesome.
