The one I used when I was interning had been completely revamped from the inside out. It was not stock by any strech of the imagination.
It sounded GREAT but in today's 24/96 technology it would be some what out of date for anything except cutting records which it will still do very well.
There were lots of problems with them in the stock state including low level hum and hiss. The unit also took up at lot of real estate in the mastering room for what it did.
The EQs on the one I used were bypassed except for the elipitical filter and we used SONTEC EQs for most of the mastering that I did. We did not have the dual SONTECs like a lot of mastering houses had so we had to do all the EQ changes in between the cuts on the record since you could not stop the lathe once you started cutting
Hope this helps.
