I use my Ampex for recording on location, recording as a mix-down deck from 8 channel to 2 channel, and playing the masters and pre-recorded tapes.
When doing direct recording I use a set of Neumann U-67s direct-in. I like to bypass my preamp when using the Ampex for playback- it has balanced outputs and drives long cables and the amps effortlessly. The results are really quite spectacular.
I used to have a pile of Magnacord machines, which were 10.5" capable and all-tube electronics. They worked beautifully. I had two that I had rebuilt- one for 1/4" tape and one for 1/2" tape. BTW, 1/2" master tapes are really something to hear... anyway, Magnacords are not as well-known as Ampex, so you can get them cheaper, and they are quite sturdy and competent.
I also have an Otari and a Studer. Between the two, although the Studer is older and somewhat more clunky in appearance, it is a better sounding machine overall. Recently I've also been using a professional grade Sony made about 15 years ago. It has a lot of nice features, but the Studer takes it to task also. Of course, sound-wise the Ampex is still the best I've heard, but its also the trickiest to use.
