Thanks for the response. I have 3 kids in college so once out, the av room gets redone.
I had an old Marantz sr18 but it blew a chip. Repair cost is probably 300.00. It just does not do the current systems justice.
The 4k, wifi and Airplay are all a +
I want the one that would be best for upgrades, dual room, TV too
Thanks.
