I don't think it would.
The pot shafts are 5mm (~.2") and 8mm (.315") and the knob is designed to work with 3.2mm and 6.8mm (roughly 1/8 and 1/4) shafts.
One does wonder though, what particular discovery they made whereby they realized that their current process was substandard and needed tweaking? Oh, and they made this discovery after having cans ready to ship.
I am becoming increasingly frustrated with the calendar function and the lack of choices for reminders for appointments. I often want to be reminded not only multiple times but as much as a week in advance of something. The idea that it's limited to one reminder and 2 day max in advance is pissing me off.
1. Slept in, glorious.
2. Had some friends and family over for lunch, dad delivered the bookcase that he and I built together for Lily.
3. Mowed the lawn for hopefully the last time. More a leaf-collection operation than actual mowing.
4. Fell in love with wipe-on poly wood finish.
Look at Outlaw's "Virtual Receiver" combos Haj, pretty sweet if you don't mind or need to have your receiver switch your video (which I personally try to avoid). Their previous receivers and preamps banked on DVI becoming the standard for video and completely missed the boat on HDMI. My TV has enough high def inputs that this isn't a big deal and just means that I have to program the Harmony to switch video inputs on the receiver when I switch tasks.
If you went with something like the Outlaw separates they have a remote trigger function so that when they aren't receiving an input they shut off. I feel like a one note horn always bringing up outlaw but my experience with them has been good and historically they've been well reviewed.
As far as I see it you're at least part way there. Good fronts, need center and surrounds. Personally I don't understand the logic of throwing huge $$ at surround pieces so really that just leaves the center channel. Hard to imagine that costing more than a grand which would leave that much for the amp side of things. Perhaps your tastes are more refined than mine and you have higher expectations which would of course blow the budget.
I see this as a "something's gotta give" scenario.
If it's a true loop out it would be non-volume dependent, i.e. muting the speakers would be as easy as turning down the integrated. If it's a preamp output you're semi-screwed. Of course you could also just split the output of your source (less than ideal) or get a switch box but I swear we've been down this road before with your speaker rig and that you had a switch box already?
