Volume Control Help.....

If you can get the specifications for it, primarily its "size" (for example, 50K ohms), you could make your own or have it made for you. It isn't hard to make an attenuator that's better than most in even very expensive preamps, like the CAT's. That's certainly the route I'd choose.

I would still like it to work with the IRIS remote, which is a different setup. When you touch the remote volume dial it becomes active and the unit is de-activated and vice-versa. I would like to keep it this way if possible, any more suggestions??

There is a person on eBay selling a bunch of NOS Hafler stuff. I think he had or has what you need. You might have to go to completed auctions to find. B
