"Monitoring off the recording medium in analog is hugely latent in comparison to digital. The analog to digital to analog loopback is much less latent than monitoring off the repro head"
Yea, if you monitor off the repo head while over dubbing. Who does that?
Modern tape machines have sel/sync which turns the record head into a playback head. Allowing playback of recorded tracks while recording new tracks with .ZERO latency Headphones, zero latency. Mixing is done off the repo head, zero latency.
Digital has latency, no matter how small. Period.
You cannot monitor the medium onto which it is recorded as it is being recorded. Latency prevents that. You cannot monitor the repro head of your stereo tape deck during mix down with any acceptable latency. Digital lets you monitor the medium with the accuracy of your monitoring path.
i think the dual op amp jensen is hard to beat in terms of robustness, i've never heard myself, nor really on the message boards, anyone speak ill about them. no "it all turns muddy when stacked" or "too mid forward!"
maybe this is better reserved for GDIY, but anyone care to delve into why that circuit is seemingly able to take anything you throw at it without fail, mic or source, vs. 312, 1272 or cohen style circuits? i guess if there's a mic that doesn't play nice* with tx input, then a transformerless input pre is the way to go, but otherwise? i should probably re-read the pdfs on hardy's site discussing M2 and twin servo with an eye towards differences...
*i've heard of this but never encountered it - anyone care to share their experience with this happening? what was weird, what was cause, what did it sound like?

Because the transformer is only a 6dB step up gain (150:600) so it handles high output condensers fine, and the 990 is a rare example of an op amp designed to mate perfectly in terms of noise contribution to a 600 ohm source such as that transformer. It's about as close to a preamp input that can't be blown up by a hot output mic as there is, I'm sure that was part of the design brief even though that part seems lost in the mists of time. The transformers are high nickel content for lowest distortion (caveats), contrasting the API higher distortion steel core transformers that make everything forward at all times, like it or not.
