What Would Be the Reasoning Behind Leaving Class D Amps On?

Some aren't left in standby that's why. I have Nord Buffers on NC500 modules it's one or the other. I set mine to stay on and NOT go into standby. I run them for 4 months out of the year, and combo of class ds and valves the rest of the time.

It takes 20-30 minutes of playing music even when I leave them on. If they go into standby, 2 hours to warm up and sound ok. Big difference in mine anyways. 

I also use class Ds for bass management 12K for subs and columns. 30 minutes to work well and warm up the VC in the bass system. 20 drivers for that alone. Cold gear sounds wonky, so does overheated voice coils. :-)

I have a pair of Wyred 4 Sound SX1000 (no R). Two day to sound good. A lot of people said the "R" model was a lot better. The fact of the matter was they have to be driven and on at least 48 hours. Mine actually "Boomed" and hated longer cables. I added some FAT speaker cables and a FAT power cable. It was like night and day between the first 2 hours vs a week later with cables. I actually kept the amps.. Powerful too, man alive!! Oh they like a good power supply to.

I added Triplite 2400 to maintain 120vac, too that was an eyeopener when I drove 100-300hz bass columns to over 110 db, with no audible distortion.. Without they got hotter and did distort at 10 minutes or so. After the maintainers.. 15 degrees cooler with the same ambient temperature, sound wonderful. 

I moved to 12Ks they will pound the poop out of your ears. Best bang for the buck on the planet.. I have 4 LOL NU12000s. I can't break one!

Where I live class A stopped when I hit 55. :-) 115 degrees is not uncommon where I live. Class Ds are king. Preamp are usually valves, here. I need a warehouse!!!

mrskeptic what is that suppose to imply? That you're tough to please or everyone on AG has a lack of some type of higher education. A higher education doesn't always equate to wisdom about a subject. Nor do fact that others have obtained in their class rooms always stand the test of time. Science is malleable these days. Just depends where you look and what you chose to educate yourself with.

Me I'll try anything at the neighbors house. I have 2 2" fire hoses I can hook to the hydrant in 2 minutes, FIRES OUT.

And be nice, your a newbie. Sure you are.. :-)
