Mine are up to song straight away, and don't seem to change with warm-up.
Class "D"amps IMO should be on 24/7. After two days on they will sound better. The power supplies like being on and coming to operating temperature. Try it before burning me at the stake.charles
Class "D"amps IMO should be on 24/7.
That's quite a generalization considering the very different class D architectures and implementations out there. Any rational analysis as to why that might be?
Because it sounds better.
IMO, all SS amps should be left on 24/7 to get the best sound.
No, it doesn't.
Maybe if you buy some reference speakers to go with your reference amp, you will hear the difference.
That runs counter to my experiences. I have a very noisy and unstable mains (some of the graphs introduce nausea), but my ncores (fed by smps600's) don't seem to mind. The fast and efficient feedback architecture of the nc400 seems to be able to correct out anything that makes it through the smps...
I myself have horrible power fluctuations including wide fluctuations and long multi-hour power cuts, which I mentioned in another thread.
I run mine using a surge-protector that also employs an under/over 180v/250v disconnect, which should at least keep them within the Hypex specs even if the mains voltage goes outside those parameters.
a) You think it is still a good idea to use these surge protectors with the over/under cutoff?
b) Whether feeding the ncores a modified sine wave could cause any damage?
Ouch! Not fun!
There is no "absolute minimum" voltage, as undervoltage won't hurt the smps/amp, it just won't work as well.
Yes it's annoying. So far, touch wood, the whole-house surge protector has protected all my devices well and I've had no actual damage. Other people who don't use often do get blown devices.
The only device that had problems was my Audiolab MDAC, which freaked out (display flashing, wouldn't boot) when served voltage of around 200v. It was either the low voltage or the modified sine wave I'm not sure, but it sure didn't like it.
It employs similar cutoffs but anywhere within the "acceptable" range it stabilizes at 240v. I was wondering if I ought to plug the nCores into this as well but reading your comments and some others it seems that might not be the thing to do.
Here everyone has to use protection against brownouts (extended low voltage) as it kills the motors in fridges, although I guess that's completely different.
Wouldn't a lower voltage lead to a higher current than normal being drawn?
So you think low voltage even over extended time won't cause any damage to the ncores?
