I'm helped my son inlaw out today with my grandson. By daughter his wife is in basic training while he, also a member of the Canadian armed forces was working later that would impact him from picking up his son from day care. Listening to a system that I gave him
AVR is a Yamaha RX-V1800
Speakers are all PSB, Alpha mains and center channel and Alpha Mites for surrounds
Subs are both PSB, left one is Subsonic 5 with a 10" driver and dual ported, the right one is PSB Subseries 2 with a 12" and dual ported as well.
The source is my PC via HDMI into the AVR.
Currently streaming a group called Black Elephant which I highly recommend.
