Welcome Gary, and congrats on your order.

I have the Ultra preamp, and of course, I occasionally desire the advantage of remote volume control. I can tell you that the output on my Oppo player remains controllable through the remote. This is not ideal, of course, but it's a convenience factor in certain listening/viewing circumstances. So, I cannot imagine why your remote on your pre would not work for you. Regardless of which attenuator you choose on your Torii, wherever you set it will simply define your max volume using your pre. I like the stepped attenuators on all my amps, except for the Taboo, which is a headphone amp, and on which, I preferred more control fineness.
