So to be clear, amp can still reach full power with sufficient voltage with the gain adjustments dialed down?
Yes.
The only way it could reach full power is IF the incoming voltage is way higher than the average 1-2 volts.
Correct and many active preamps can provide more than enough gain to make up for the reduced input sensitivity on the amp.
Depends on the scaling factor on the amp/attenuator setup. I would argue that at 9 o'clock, the attenuation would be significant to restrict the output power from achieving anywhere near full output from MOST preamps.
Yep. I think we are getting wrapped up in semantics.
No, it can't (under normal usage). The only way it could reach full power is IF the incoming voltage is way higher than the average 1-2 volts, and the scaled down voltage was sufficient achieve a full powered output.
Maybe if you try reading a little slower and think about what you have read it will help.You went from painting with a very broad brush to a little thin line I can barely see.Of course each system will be different, so gain staging will vary.
(that it is very doubtful that full power can be achieved with the knobs at 9 o'clock),
It's important that listening impressions are taken in context. It's already been posted that the amp sounds different (better) when the volume knobs on the amp are at 9 o'clock. That means that the efficiency of the speakers, along with the input, needs to be understood to evaluate. If speakers are say, 85 to 87 db/w, and a source of 2 volts is connected, listening impressions could be very different.

If speakers are say, 85 to 87 db/w, and a source of 2 volts is connected, listening impressions could be very different, as the amp may not achieve full power configured like this. The input volume knobs may need to be at 2 to 3 o'clock to achieve full power.
Those Crown amps look intriguing for the money. I have a Virtue 2 on my Maggies in the living room, I could put a Crown on those and give them the power they really want, and another one on my spare set of M&K's and finally get a theater going out there. Some EMO theater receiver action and I'm set.I knew once the Ncores were introduced, class D would get better and cheaper, quickly. I doubt the Crown is on par with Ncore technology, but I've heard the TBI Millennia (which wasn't even close to Ncore in any way possible, was OzarkTom's modded tour amp, not even close), and it was a very good amp.Eventually though, I'd say within 5-10 years we will have Ncore class amps (best of the best sound quality with no need for external power filtering or stupid cables - even the Crown amp advertises this), huge power, supreme performance, commodity prices.They will be dime a dozen and far superior to the ancient, extremely expensive space heaters that came before.
It is nice to have the option to lower it or crank it up. 9 0'clock setting gives me about 20-25 WPC on my 85db Zellatons.. 12 o'clock and it is more like 75-100 WPC. I will never use the 375 WPC.Listening impressions are coming shortly.
