Just gotta say....
that my old
Fostex X-26 was the best sounding 4 track cassette of it's time. What you heard while monitoring to tape was exactly what you heard coming off of the tape, and the meters were extremely accurate. These are both things I could never count on with any of the Tascam analog tape based products, to include their 1" 16 track, 488, and all the PortaJunk stuff.
Fostex makes some of the best record/playback heads in the business. Their quality control standards are quite high.
Many people don't know that Fostex in Japan is like JBL over here. They make some fine sounding speaker systems. Not that speakers and recording machines have a whole lot in common, but I think that Fostex is a fine company that makes very good products.
My D-5 DAT machine is over 3 1/2 years old now, and has seen some serious use with no problems what so ever. At the time, it was over $500 cheaper then a comparable Tascam DA series DAT machine.
I am no Tascam fan. Yes, they generally make dependable products mechanically speaking, but I have never been impressed with the sound quality of their gear, ANY of it. Don't let Tascam's reputation of reliability be the only deciding factor. Plenty of other companies have a very good reputation with making quality products that are reliable.
