I recently demoed the 683 and 684. Honestly, I liked the 684 better, for $500 less. The 3 way implementation just seemed disjointed. The 2 way was much more integrated. This was for a home theater and music setup and we paired the 684 with a NAD T 757 and I liked the sound a lot. A NAD stereo integrated would make a nice match, however this setup was for classical, folk, jazz, not rock. PSB and Paradigm are other contenders in this price range.
Personally, I stay away from Rotel. I find them forward and bright. But, that might be what you want for rock. I just find them fatiguing.
The NAD C356 (or C375) includes a DAC and USB input so it would be easy to also do computer music, but it does not have a phone input. You can also add a phono input, but I am not sure of the details. Spearit Sound sells new and refurbished NAD amps online.
I also like the Naim Nat 5-i2 (or its replacement), but it is more money and does not have phono or DAC. But it is a great integrated for the price. I have used it with Totem, but not with the other speakers you mention.
Both the Nad and Naim will be less "analytical" than the Bryston. That is all about your tastes.
Personally, I would start with simple interconnects/speaker wires and add those on over time.
Good luck! Building this system is hard work but also fun.
