Wow! I cannot believe how quickly my OP went off topic. No, I am not changing my "stupid" AirLens. And no, at this point, my DirectStream DAC MK1 is not "on the chopping block." I could not have been more clear in my OP, that the equipment I have is the equipment relevant to this discussion.
Go take that discussion elsewhere please.
I appreciate audioman58 starting in the right direction mentioning Motorola 8702 and LHY SW-8 switch. Please stay on OP topic. Greatly appreciated.
And to zlone, excellent point - no, there's nothing in my current setup that bothers me - nothing. I am just exploring a potential step up allowing my ISP signal to be possibly better than what I am experiencing through my current Netgear Nighthawk CAX80 modem/router device.
