virtuo is okay.
early models have issues with black spots appearing on the LCD panels due to a manufacturing defect. later models have no panel issues... but some issues with bad caps on the backlight inverters. newer ones have LED backlit panels and have issues with the caps going bad on the LVDS board. the later 2 being fixable... the spots, not at all other than panel replacement. good luck finding a panel to replace it....it's a weird size and wasn't available for long.
the computer is decent. it's output audio via regular headphone jacks so no messing around there. you will need a "red" DI box to convert the audio from the computer to the amp (amp accepts balanced audio over ethernet...the IO board does this so you'll have to sub the red DI box to do this.)
the card reader is worthless as it's been disabled due to new PCI credit card processing rules rules... making it non-compliant.
the stand should have woofers built into it... it should also have some satellite speakers attached to either side as well.
Sorry to bother you again, I'm still considering to exchange the Angelina for the virtuo, but I'm thinking on keeping the Angelina amps. By any chance, do you think its easy to modify the blue amp to make it work with reguralr sound, I mean without the red box? Or since it comes with a stand speaker, it should have the red box already? Thanks for your time.
i don't know how the stand is configured exactly... they are made by a 3rd party.
the amps are the exact same amps... they just stuck 2 of the modules in the same box.
with using a red DI box, you don't need to change the amps at all... it's literally how they interconnect.
the "red" DI box has RCA input and and Ethernet cable balanced output. then, the other end of the cat 5 plugs right into the amp. you have to supply 12v to the DI box to power it. you can buy a pre-made power adapter that plugs right in, or just wire on a 12v power brick or other supply to the appropriate places on the board.
the "BLUE" DI boxes convert the balanced audio ethernet back into standard RCA (for instance, connecting from the IO board zones to an external house system)
since you won't be using the IO board, you won't need any blue DI boxes unless you want to convert your computer audio to balanced with a red box...send it long distance over an ethernet cable, then convert it back to RCA to hook up to a house system.
one red DI box can feed audio out to 2 amps when externally powered, which is enough for the amp in the virtuo. (since it's 2 amps in one case) if you need feed a DA415 blue amp as well, you'll need another red DI box for that amp.
the DA415 amp will likely need the caps in the amp serviced. they all do.
