Thank you for the info jautor. That makes perfect sense.
I will go that route for now and look for the amp.
For the amp would nuvo D460 work? or Do I need different amp brand?
I understand that the simple impedance-matching speaker selector will match at same ohm level, so I would guess 8-ohm stable amp would do the trick? or do I need to go with 4-ohm stable amp?
Also for the software, I'm actually purchasing the system with software.
Question is software might be older version, would older version software work?
Once I receive the unit, I will update the status of install.
