I'm curious why the Grand Concerto seems to be mentioned alot recently. What are the key diferences between it and the Russound CAM 6.6? They seem pretty similar but with the Russound at a lower point so I'm curious why the GC seems to be mentioned more. I'm sure there's something I'm missing here
I will only state a few comparison facts, the rest really just comes down to a personal decision. The Grand is a new item, so some of its press may be due to that, but the facts are....
Starting with price...
CAM6.6T-S2 is $3,899 for the amp with 6 keypads
NV-I8GMS is $3,499 for the same configuration
To be fair, the CAM includes a single AM/FM tuner. For the GC, you would need to purchase the NV-T2DF whicj is a dual am/fm/weather tuner for $799. So the GC would be $400 more with the tuner, but it is a more capable dual tuner with weather. Or, look at the CAM6.6-S1 which is $3,249 and does not have a tuner, but has inferior S1 keypads. I do not see a configuration with no built in tuner and S2 keypads. Keep in mind these are retail prices and not ebay or dealer prices, so you exact costs may vary, but retail, or 'advertised' price is the only true comparison.
The GC is the first system to use an 8 line capacitive OLED keypad. There are no membrane keys to stick, wear, etc. It is a flat glass screen. The technology comes from the kitchen appliance technology. Look at things like the GE profile line and you will see what the keypads look/feel like. They are very clean and elegant looking and have 8 lines of text that you can even send custom info too, like caller ID, temperatures, reminders, etc (assuming you use NuvoNet and hooked up to an HA system). I personally think the keypad is really nice, but others may like the more traditional ones better.
The GC is twice as powerful. It has 80 watts of clean Class D digital power per zone. The CAM is 40 watts of analog power.
The GC contains the same 6 amplified zones as the CAM, but it also has an additional 2 unamplified zones that you can either add full amps, or smaller amps like the LSA40 local source amps for smaller rooms.
The CAM has 2 fixed/variable outputs, the GC has fixed/variable output for each zone.
The GC allows you to use Input source 6 as a paging zone, the CAM has no paging capability.
And I'm sure alot more can go into a complete comparison. But for a very similar price, the GC has twice the power, is digital, has nicer keypads (imho) and some major additional features.
I don't know for sure, but maybe thats why it so popular right now. The best thing to do if at all possible is to see them both live at a show like EHX, and look and listen for yourself.
