Amp and preamp on same outlet?

also

the female end of the Krell cord is unlike any of my other gear and has horizontal bars like this

Ct0517, the specified $11,500.00 is also the cost of the amp I paid before all the modds and refurbishment,the modd job was with shipping back and fourth, buying two pallets 2 diferent times, krell kept the first one and sent one back half the size of the original, so I bought a new full size pallet,straps 2 different times, fork lifts damaged the first 4 straps, $4,000.00 total for me, shipping the amp was $300.00 one way, and the amp went to krell a few times!, the actual cost I paid to krell was $3,157.38!, so wih the purchase of my amp, all the shipping, all the material to ship with, you damn straight I have $11,500.00 into this amp!, also, I do NOT have a 20 amp line, I have a dedicated 30 amp line, 30 amp breaker, copper 10 awg romex 3 conductor line,and yes I did get NONE oem brand caps, tweaked power supply, alot of new transistors, new heat sensors on both sides of the amp, 6 of them, 3 for each side, etc..., I have a huge bag of the old parts!, and I got new proccesors on each side of the amp, also, I am tired of telling all of you that the 30 amp single pole breaker made a huge difference in sound and the operation of my amp, I care less what any one says, all those that have done this convinced me to use the 30 amp breaker, it works great, again, with NO issues, BTW, I also renewed the cosmetics on the out side of my amp too.

I have come late to this party, and I didn't read every single post, so forgive me if I missed something important to the discussion.

First off, Krell IS NOT recommending that you simply replace your 15A breaker with a 30A breaker. What they do recommend is that in order to get the best out of the amp, use a 30A breaker with the APPROPRIATE wiring on a DEDICATED line. Appropriate wiring would, of course, include the appropriate outlet and plug.

Now that being said, IF you have a dedicated line with 10# wire and a 30A breaker, the use of a high quality outlet and high quality plug, while NOT meeting code, would still be fine as far as safety issues go. The 20A Furutech, WattGate, ect. high end outlets and high end 20A power cords (plugs) are way over built and can handle the load presented by the amp even in the event of catastrophic failure. So there would be no fire danger. The amp in normal operation does not draw enough current to cause any problem at the outlet or plug.

So technical wiring issues aside, does the 30A setup help the sound? Does a dedicated line help the sound? Do Power Cords help the sound? If you have a revealing system, you probably already know that EVERYTHING matters. The only thing is how much, and is it worth the expense.

My personal experience has been that all these things help improve the overall sound of my system. If you don't believe that Power Cords make a difference, I'm probably not going to change your mind, and I would think that if you do not believe PC's make a difference, you are not going to believe that a dedicated line can make a difference, so why even discuss a 30A breaker setup? If you do think PC's make a difference, you should realize that the 30A setup COULD at least make a difference, and from my experience, it does.

Good listening,

jea48, ct0517's tech guy did not work at krell!, no one knows krell amp's like krell does them self's, and Dan D Agostino, and Steve Lacrone that use to be the service manager there at krell up to 2009, Steve Lacrone owns a company called, The service Department Home, he specializes in all Krell equipment among other brands he services too, you may do a web search and see the company, he is located in CT, not far from Krell.cheers Jim.

And to the OP, having your equipment on separate dedicated lines does improve the overall sound quality of your system. That is why ARC recommends it.
This does not mean that your system cannot sound good on a single outlet, just that it would sound better on separate circuits.
Best,
