Pre-recorded Reel-to Reel tapes

About 30 years ago, I had a nice 4 channel Reel-to Reel tape machine. I think that was the best fidelity I've ever heard. I have researched a little, but haven't found many pre-recorded tapes available. I guess it's almost like searching for 78 records. I'm loving my vinyl, but wish I could find a place that offered many titles of tapes. Is there such a place?
E-Bay. Yes, pre recorded R2R tapes are hard to find, but e-bay has a vast selection. While most are 4 track, 3.75 speed, the treasurers are 2 track, 7.5 speed. A while back a Miles/Blue of the latter vintage went for almost $2K. Barcley Crooker tapes, perhaps the highest quality of pre recorded tapes also are sought out. Some of the latter go for $50 plus, however most are classical titles. Another area of pre recorded tapes are 'broadcast' masters. Most come on 10 inch reels, and are 2 track. The best of these are AFRTS tapes produced by the government for the military broadcast system. I have a few hundred of the latter and quality is very high, our government produced nothing but the very best, after all it was using taxpayer funds. I have about 6000 tapes in my collection and enjoy them everyday. I have about ten working tape machines.
sitting by the E of the Bay, listen to what i say...
I have heard great things about this company,, never actually tried them myself.
Forgot to mention, I had a perfect condition high speed two track Revox B77
Mk11; sold it two years ago on AudiogoN. Big mistake, wish I had kept it and
tried one of the TapeProject tapes on it.
I have 20 or so......the sound quality sucks....iTunes would sound better...

However, there is something special to watching an old reel to reel working.

If the sound quality is so bad, why buy 20 of these very expensive tapes?
Open reel tapes on Ebay -- they list maybe 8,000 at any given time -- are a total crapshoot. Most sellers don't have a tape deck to play them on (they found them at estate sales or wherever). But there are real gems to be found if you're patient (and obsessed) enough.
it all depends which quality you get. For 1st copies or even 2nd copies you pay quite an amount. I was able to get some very good copies. Also got the 1st series of The Tape Project, some among them are good. I use the Tapes on my A820 and C37. You should connect the Speaking Machines to a good sounding system - and voila, now you know why well recorded tapes sound superior to vinyl. No question about that!
Most older prerecorded reel to reel tapes were actually dubbed high speed, which we all know created a poor quality copy. Factor also that they were dubbed to a slow playback speed, its not hard to understand why they never really had a fan base. I had a Revox high speed B77 mk2 and it was terrific. It would not however have been optimized for the tape project stuff since some of it is 1/2" rather than 1/4". Lastly the tape project software is WAAAAY overpriced.

Here are some Reel-to-Reel tapes from International Phonograph Inc.

I have no affiliation with the company. Just passing some information along that I found on the net.

Buconeer, you might note that all Barclay-Crocker tapes were Dolby-encoded (except the few that were dbx-encoded), so you need a Dolby deck or a way to cut the highs if you play them back on a standard deck.

That 2-track "Kind of Blue" has only 3 of the original 5 tracks, which works out to $36 minute!

Pretty much the only reason to get into reel-to-reel today is that the great tapes sound so awesome :-)
@mgattmch....Why? That's a great question....sometimes in the evening I drink and hit ought top see all the crap I've purchased this way. :)
The International Phonograph tapes sound fantastic and are 1:1 dubs (done with great care) of safety masters from music Jonathan recorded himself.
Typical audiophile (and nothing wrong with this). In love more with the toy than the music.
I am old enough to remember the r2r craze of the 70s...our neighbors worked for an FM we had access to a vast array of tapes at cost prices...vintage sansui receiver, dual turntable, advent speakers, akai memories are not as fond as others...tape machines are notoriously finicky....with many moving parts...kind of like owning a vintage was always in need of something...that being said...the fidelity wad very good...moved on to cassette tapes in the 80s...huge downgrade!
They are recorded very well and sound astonishing IMO.

I have most of The Tape Project tapes plus a few dozen other Safety Master tapes, you haven't analog at it's best until you hear one of these tapes!!!
I just bought a 4 track stereo TEAC A-3300SX, and am starting to assemble a collection of pre-recorded tapes. With the first, “Best of Cream” at 3-3/4 IPS I was thrilled to hear those favourites like “Badge”, “White Room”, “I Feel Free” and “SWLABR” with bigger, fuller and richer sound for the first time all over again. “Days of Future Passed” at 3-3/4 is on its way, and I can’t wait. Looking for other landmark classic Rock pre-recorded releases like “Strange Days” and Zeppelin IV. Also looking for some recommendations. 
For whatever it’s worth, Amoeba Music stocks every format of tape except open reel. Go figure.
