Recording Degradation on Recording to reel to reel

Everything is relative, i.e. perfection, darn good, good enough.

I have over 500 pre-recorded tapes, 7-1/2 ips. Inherited some, bought most on eBay. Played how many times?

Despite what people say, these tapes, and the Technics X2000r player are my best sounding source material.

I have many albums: CD; LP; R2R. Everyone picks LP over CD and R2R over LP, despite the fact that there is tape hiss in quiet passages and the S/N specs are worse than others.

Re-recording: IF the magnetic materials have not deteriorated, good to go. Repeated play, 60 year old tapes, no bleed thru, still sound better than other sources.

15 ips; 30 ips, gotta be amazing. I had a Teac that played 15 ips and 7-1/2 ips (they do not have 3-3/4 ips typically). I gave it to a musician friend and stuck with the X2000r (last pro-sumer deck Teac made). Plays big reela, 7-1/2 and 3-3/4. I do have some 3-3/4 ips, nowhere as good as 7-1/2, and LPs will beat them, but I can play them.

My tapes I made myself, FM simulcasts, still sound great.

like I said, if a perfectionist .....

I agree with you. The quality on some of those early pre-recorded 7" tapes is drop dead amazing. I’ve got a Temptations Gr. Hits Vol. 1 (7" pre-recorded) from the 1960’s, and there are a few dropouts on it (mainly from use), but the quality...OMG! I actually compared it to the commercially sold Motown CD, and that CD has more dropouts on it from their master tape than on my 7" pre-recorded version.

I grew up with my dad's Ampex tape machine and hundreds of prerecorded tapes, jazz and classical. The tapes were all 7.5 ips. Back then turntables, tonearms and cartridges were not near the quality they are today and in spite of considerable tape his the Tapes were vastly superior to LPs. Today the situation has been reversed. Modern upper level turntable playback especially with 45 rpm records recorded from uncompressed files are vastly superior (and quieter) than those old tapes. I can not speak for 15 ips modern transfers as I have no experience with them. 

Back in the day, I had Sony, Teac and Revox reel to reel recorders and I bought many pre recorded tapes.  One of my favorites was Abraxas by Santana. When new, it sounded amazing!  But after more than a few plays, you could hear the hiss increase and as the hiss increased, the high end started to disappear and sadly, the tape started to sound like mud with tape hiss. 

Another thing to keep in mind is that those early 7" pre-recorded tapes were sooo close to the master, that I’m not sure one can get the same reproduction today, even with today’s one steps, and other pressings (SACD and 192 kHz files included). It’s one of the main reasons why they are so coveted even today. Granted, the S/N can’t approach today’s technology (and S/N is a definite priority with me), but the dynamics (on the right playback equipment) on some of these tapes is just mind-blowing. I only own 7 of them at the moment, but whenever I throw one on, and put on the headphones, I’m still to this day blown away by their dynamics, to the point I feel like I’m almost sitting at the mixing board. Don’t forget to keep those tape heads and capstans clean.
