Looking for a new home theater AVR that can drive 4ohm load. 9 ch. Budget 3k. NAD T778 came highly recommended. Need advice. Thanks 
Big NAD fan here.  Owned a flagship AVR in the past and currently using an older T175HD HDMI pre/pro and a couple of Acurus amps in my main HT rig.  While you could go with NAD's flagship AVR the T778, why not opt for the T777v3 and get a high current 3 channel amp to drive your LCR.  Even entry level multichannel amps(Outlaw Audio, Monolith) will have better 4ohm capabilities than most if not all AVRs on the market. 

Just my take.

That would be my take as well.  Look for a multi channel amp to drive as many speakers as possible, and use a budget pre AVR as a pre amp (and possibly to drive rear or ceiling speakers).  Then upgrade as funds allow
What if I wanted just one box solution ? Is there a worthy AVR that can drive heavy loads ? What about anthem ?
Yes Anthem would be a good choice.
The NAD T777v3 or the T778 will provide plenty of grunt to drive most HT rigs in most rooms.

I am also looking at the Nad 778, I currently have separates now and want to downsize to a good AVR like the Nad and get rid of additional cabling like the XLR 's and get a cleaner look don't need all the power for a couple of surrounds still at 5.1 I may go with the receiver and a 2 channel amp for music. Which would be less wiring and less space then 5 channel. Just my 2 cents
I already ordered it. 2 month wait! I think it’s the coolest AVR out there at the moment 
Did you get a good deal on it? I saw they are back ordered everywhere hence the "wait" glad to hear looking also at the Lexicon RV 6 , and the new Anthem MRX 540, 740 but like the Nad the most and may just wait also. Thanks for your post
