Hey my brother.
Yup, both are the same thing, used to be branded Jensen. Hardy sells them, I believe under license from jensen, don't know if the new models are labeled Hardy or Jensen, but the web site still has a photo of the jensen labeled one.
I talk to Steve Hogan just about every other day, he was the og designer of the c version of the 990 DOA when he was at jensen. Great guy. He modded my console and pres, and a bunch of other stuff in my place. Very smart, and he overbuilds everything he gets his hands on. He has taught me so much that I would have been in the dark about without his help.
The M1 is really nice too, but the twin servo is amazing. Actually they are both amazing, but the thread is about "Holy Grail"....so....
I remember first hearing the Hardy M1 style retrofit preamp in a Sony console in the 90's, and was amazed by it with bass guitar and kick drum. That was my first exposure. Seemed to go on and on down forever, and I had never heard bottom end tightness and clarity like that before.
Steve is also making a new batch of 990c DOA's himself right now, but they don't fit the Hardy / API form factor or pinout, they are slightly larger. He is taking extremely painstaking steps to match everything down to the inductors / chokes etc. on each and every one by hand.
Anyway, this is what I was talking about (for the OP's benefit):
The John Hardy Company Jensen Twin Servo 990 2 Channel Version
On a side note, an old 90's version of the Twin Servo just sold on ebay for pennies on the dollar. Crazy. If I had had the $ this last week, would have snatched it up.
Peace,
