Amp and preamp on same outlet?

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,

Ct0517, look, I do not know what krell amp you have or owned, my amp is hard wired straight to the power supply!, not going to any bus bars, there is none!,I myself have seen this inside my amp, and krell also has confirmed this to me!, my amp does NOT consume 30 amps!, it simply spikes over 20 amps, what I have tried to make clear to all of you, I have a 30 amp dedicated electrical line, a 30 amp single pole breaker, and a wpo that is 20 amp's but sustains the amp spikes over 20 amps with no issues, my amp runs smoother, cooler, bigger sound stage, hugely more dynamic, my amp is no longer choked by the 20 amp breaker.

@Audiolabyrinth
thanks for clarifying the costs - that makes sense.

jea48, ct0517's tech guy did not work at krell!

Well of course not he is Canadian. But he has worked on the Master Krell Ref's.
Can everyone working in the service dept at Krell these days say the same ?
Now..... I don't "really" care about the answer - just think about it.....

Ct0517, look, I do not know what krell amp you have or owned

Not sure why not. I show a virtual page. You can see what I have.

BTW what speakers are you using with the amp ?

I have a huge bag of the old parts!

Sometimes a picture is worth a thousand words. After all the public chat forms imo are for learning sharing and a little fun.

here is a pic to give the others reading an idea

My two rooms are in the basement adjacent to one another. B is closer to the Fuse panel over A the main room. I left a path - removeable ceiling - going from outside Room A, past Room B to the fuse panel for upgrades and changes. If I ever chose to add new line (30amp service), it would be very easy laying new line over the beams. The only costs being the electrician putting in the breaker.

Have a nice day. beautiful looking Sunday.

Happy Listening.
