I got the F8 today and I've been playing with it for around the last four hours. I had a late change of plans and I'm leaving tomorrow morning for a festival, so it's going to get a workout this weekend.
This thing has an amazing array of features and the review I'm thinking about doing is going to take quite some time, but it will be worth it. I might start a thread and just add to it over the course of time because if I just wait until I review everything and issue the review all at once, it might take awhile before I get a chance to test everything out.
OK, my first impressions are that this thing is amazing. I'm holding my breath about how the preamps sound but it won't be long tomorrow before I get to check them versus my AETA PSP3.
So many positive impressions right now, with the only 'new' negative (other than the items we've discussed previously) is that so far I haven't been able to find any kind of a hold button or hold feature on it. So far, I'm not seeing any way to gang any of the level controls. Even when you link stereo channels, the level controls aren't ganged. However, I've got a feeling this can be resolved with a firmware update. I don't have time tonight to explain in detail and I'll probably have to think it through some. Don't hold me to this yet though.
Construction really seems top notch and solid. The SD card covers are spring loaded doors, not rubber covers and a spot on as far as how they function. I've spent at least a couple hours in the menus now and they're very intuitive and easy to navigate. That said, since the unit is feature rich, it will take some time to learn all of the menu selections.
The buttons are all on par with the buttons on a 7xx with the same basic feel and feedback...though the buttons are generally smaller.
The main toggle knob is black knurled metal and with a very solid feel. The knurling on the knob give you a solid grip. Turning the knob provides a ratcheted detente 'clicky' feel with clicks being succinct and sharp, without being overly clicky feeling (I'm not sure if that makes sense). One click equals one spot movement in the menu up or down. Push in on the toggle knob to select an item from the menu. Again, the click when pushing (as opposed to rotating) is succinct and provides a definitive click with no mushiness whatsoever.
I've done about an hours worth of messing around with the bluetooth interface and, short of wishing it was wifi compatible, its everything I'd hoped for in terms of control. Haven't checked range yet, but my earlier concerns about accidental button pushing are mostly a non-issue. The delay between what you see on the main screen of the F8 and what's seen on the ios device is barely perceptible and won't be an issue.
Sorry I can't write more, but I want to do some more with it tonight so that when I get to the festival tomorrow, I don't mess anything up. Stay tuned next week because I think the recording I do this weekend will really provide a good indication of what can be expected from the preamps...at least for the live music taping crowd.
