Help me to decide to this NAD T758 and NAD T777

[Relly Carreon]

Both MA Silver 8 are RX8 are 4 ohms nominal.
Marantz receivers can drive 4 ohms speaker as long as you don't push them to the limit. I installed a Silver 8 5.2 recently using a Marantz SR-7010 in a large room and there was no problem at all. We were able to listen very loud with volume at -20.

Hi Peng Thanks for your advice
I have to consider also this Marantz SR7010

The NAD receivers are all rated for handling 4ohm speakers. If nothing else, they're as close to "blow up proof" as you'll find in regards to their amps. The "soft clipping" feature will be the thing that saves your receiver...and your speakers.

I check the NAD T758 and it says it can only drive 8ohms speakers. I don't have a problem for my 4ohms Front speakers. Do you think T758 can drive my rear, sides and center speakers at 6ohms? Thanks!

I have one and it's right in the owners manual the rating of 234 watts per channel dynamic power at 4 ohms (two channels driven.)

My KEF R500 are known to dip down to 3.2 ohms yet I can run them right up to reference level on the receiver. When I am driving all 5 speakers I can get to -5dB and it will go into protection mode after a few minutes. That's awfully loud though, enough that my wife complains at nearly the same volume.

Lol! Thank you very much Sir! I really appreciate all your response and I learned a lot.

I think you would be better off with the Marantz as long as it has good protection from overdriving the amps as the NAD's do. The SR7010 is more powerful than the T758 for certain, and has a lot of video related features you may want now or in the future.

Thanks Sir. Now I need put my attention to this SR7010 and T777 I think this are the best fit for me right now. I like the NAD because it has an extra outlet to hook my MC7100. as much as I can I don't want to plug it directly to wall outlet and only NAD had an extra power outlet.

Of course a biased opinion from me, being an NAD owner. I would LOVE to have the T777. Yes, they are slow to get current technology into their products but unless you're in a hurry for 4K (and there are workarounds to that) the unit has a tiny bit more power than the SR7010 and that feature you like.

Where are you located? I bought locally through a dealer many here use via the internet, Spearit Sound and they are the central clearing house for NAD's own open box returns and refurbished units.
