Is this set to support google cast in the future, or do i have to keep using the chromecast itself?

Hi, this receiver is Google Cast ready. A future firmware update is required. Thank you, CB

Will the system work as well with a power transformer (that transforms it to the European standard of 220w)?

I hesitated for two years because I was worried about using a step down to power my Onkyo TX-NR 646. I eventually did and have not had any issues for at least the past 5 months that i have used it. My worry was not about the stepped down voltage (I certainly won't believe anyone who tells me it will have any effect). My worry was with the frequency, 50Hz vrs 60Hz which the stepdown cannot convert. As long as there are no moving motors or internal clocks, I bet with all my ignorance in electronics, sound and electricity, that you will enjoy your amp. Your ears must be really super sound sensitive to notice any sound "degradation", whatever that is. Beware of what interested parties tell you. If you are concerned about warranty, sure follow their instructions to the letter.

Does this receiver support unpowered subs?

Hello, you need a powered sub for this unit. A subwoofer that is powered by the receiver is not supported on this model. -DH

Does this receiver have a graphic equalizer?

HI, it does have an equalizer. It is in programming under speaker settings. There are three presets that can be programmed. Thank you, CB
