I'm sorry but I continue to be obsessed with cassettes. Someone help me, I can't stop buying them from Japan...the prices are so good compared to the eBay I can't stop myself...
I have more than enough TOTL tapes to last me a long, long time after the Revox arrives, here is where I stand with different types at the moment.
Axia AU-IX (type I super ferric, Japanese market only)
BASF Pro II (type II true chrome)
Maxell XLI (type I super ferric, Japanese market only)
Maxell XLI-S (type I super ferric, one of the best)
Maxell UDII (type II, mid range type II I found at a thrift store)
Maxell XLII (type II)
TDK AD-X (type I super ferric)
TDK AR (type I super ferric)
TDK AR-X (type I super ferric, one of the best)
TDK MA (type IV)
Sony HF-ES (type I super ferric, one of the best)
Sony ES II (type II)
Sony ES IV Metal (type IV, TOTL metal tape)
68 tapes in total. I think I'm done, but there are still some tempting deals over in Japanland. I'm paying 1/2 to 1/4 the prices you see on US eBay.
I've invested heavily into type I super ferrics. I think these are the most interesting types of tapes. They did not sell well in the USA and Europe, and as such they are relatively uncommon compared to type II and IV. The prevailing theory is that they were snubbed due to their being "normal" bias tapes, and many people associated with type I tapes as being of inferior quality. These "super" ferrics however, are cobalt doped and can take very high levels of signal, close to that of metals. They are also low noise, comparable to that of type II, but maintain the superior low frequency performance of a type I.
Nowadays, these are some of the most sought after tapes, with many believing they are some of the best ever made, having the most natural timbre, even outperforming metal tapes. Also, because they are normal bias, they are compatible with just about any tape deck or walkman, as opposed to many type II tapes that have very finicky biasing requirements to get the best sound out of them, which requires high end gear.
So I hunted down some of the best super ferrics out there, the Maxell XLI and XLI-S, the TDK AR and AR-X, the Sony HF-ES, and the Axia AU-IX.
Here is a set that just arrived, a sealed box of 1988 TKD AR-X. One of the best tapes ever, but they weren't cheap.
This time period was the heyday for cassettes as a format, where companies like TDK, Maxell, Sony, Fuji, That's, BASF were trying to make the best tape possible. Rest assured, 99% of the stuff people were listening to on prerecorded cassettes was not anywhere near this level of quality. Most were made on low quality, noisy, type I tape. I've already experienced that you can get really excellent sound from the format, even with my rinky dink recording setup with a portable two-head recorder. I am dying to get the three-head Revox deck and see what it can do.
Is it the ultimate analog format? No, of course not, but I do think it's very underestimated. Also, it's fun as hell to collect tapes, make recordings, and have a high quality analog rig right in your pocket
