after months of research I finally took the decision to switch from my classic amp and software based amp simulations to the unpowered KPA toaster in combination with Yamaha HS 8s or headphones for private use at home only without recording intentions yet.
In terms of connection I would like to ask for your advise on how to connect the devices to get the best sound quality as well as flexibility to add another instrument like keyboard or an edrum-set somewhere in the future.
Please note I need to connect my mac to the HS 8s/headphones as well to play along.
1. guitar -> 6.3 mono jack -> kemper
2. KPA main out -> 2x 6.3 mono jack -> audio interface (which Focusrite item to recommend?)
3. mac -> usb -> audio interface
4. audio interface -> 2x 6.3 mono jack -> HS 8s
Thanks for your support
