I will not even read the other post!, NO!, do not ever do that. |
Audiolover718,I can tell you if I plug anything into the same outlet-dedicated circuit as my Krell 700cx, I can hear a difference of poor quality, the amp litterally suck's the required power-current for a pre-amp,cd-player, etc... right out of the componet's requirement needs to operate the way it was designed, then when I use a pre-amp, cd-player etc.. on it's own dedicated circuit, wala!, the dynamic's and transparency, sound quality in general is back with a vengence!, to conclude what I have said here, The only way this scenerio will not happen to you is if you have a very low current draw amplifier that does not require 20amp single pole breaker to a 30 amp single pole breaker dedicated circuit line, also, the last time I lived in an apartment, LOL!, I had a krell fpb-200 and the amp literally dimed the light bulb's and blew the bulb's untill I installed a dedicated line for the amplifier, just my exsperience's here that has happened many time's over, what do I know, ha, he,ha, hope this help's you. |
Listen everyone, I have a dedicated line rated above 30 amps!, their is no issues,I have said numerous times, I have a 10/3 romex, meaning 10 awg 3 conductor dedicated line, it is the same as the captive cord on my krell 700cx, seems no one is listening to me more like it! |
Jea48, also, this captive cord is a 10/3 copper power cord,when I get the money, I will be changeing the wall plug to a furutech or oyaide for performance, It seems I really don't need it, but I can always return it if something like this wrecks my sound, I am a skeptic by nature, so we will see Jim, cheers. |
Mitch2,That is funny!, my amp got way to hot on just a single pole 20 amp breaker, krell told me that my amp was designed to run on single pole 30 amp breaker, guess what, I did what krell told me to do, my amp has incredible dynamic's, bigger sound stage and transparency, and now for the kicker, the amp never run's hot and operates smoother, my krell kick's a 20 amp in the Axx! |
Thankyou Almarg for clearing thing's up for me, A very good job indeed, yes, I have to go about thing's different with my amp, also, a couple of good friend's here on audiogon confirmed what krell told me, why?, they own the Krell 750mcx mono block's, these guy's talk to me often to help me, they have even bigger than my amp, the 750mcx has the exact power supply as my amp, however, the mcx amps have two!, oem to oem, the 750mcx has a bigger sound stage, but with my modds,up-graded none oem caps through out, tweaked power supply, up-graded most transistor's to higher grade,etc... it should be awful close, cheers. |
thankyou p59teitel, that is what I have, two furutech GTX-D Rhodium's,and wall frame and cover plate, I have all the box's too, just have not had time to look at the box's and info, cheers. |
Audiolover718, This support's what i have said, why not do what ARC has said? |
|
Jea48, Asit turns out, my krell manual for my amp says to use 20 amp single pole breaker min, they put it in their manual, that means 20am will work, really terrible, but you can get by, the 30 amp single pole allows my amp to get the correct current, does it use all 30 amps, of course not!, however, it spikes well above 20 amps, the amp never runs hot like with the 20 amp breaker, way more dynamic, bigger sound stage, it's a fit! |
thankyou ct0517, it is patrick bresnahan that asked the technician's and R&D design team about the 30 amp breaker, this was NOT my idea at all, it was numerous other big krell amp owner's and krell that made this sugestion to me,however, Patrick is correct about the male wall plug, I have no issues at all, but I also said, I will be getting a high performance male wall plug for sound, Not any thing else, if I decide I really want one, currently, I do not, cheers. |
Jim, science is not all!, I am telling you, please listen, My amp does not get hot any more, got a bigger sound stage, runs smoother, hugely more dynamic, Jim, how do you explain why a single pole 30 amp breaker did all this when a 20 amp breaker choked the crap put of my amp in every way?, also Jim, this is very incredibly noticeable of the difference between the 20 amp and 30 amp breaker on my amp,I also have a $240.00 top of the line furutech GTX-D Rhodium for an outlet with the breaker, works safly, the outlet is cold all the time, period. |
Jea48, I do not understand why you would make humor of the truth, I had numerous others with the Krell 750MCX mono block's and the stereo Krell 700cx say the same thing, they encouraged me to use the 30 amp breaker as did krell them selfs,no one knows it all, we all learn from each other, I did not believe that the 30 amp breaker would do any thing either, but when I got 20hrs of break-in on the breaker, it turned out to be the best cheap tweak ever I have done in my life time, the benefit's was worth thousand's of dollar's to me! |
Jim, you do not understand, Krell runs 30 amp braker on every krell 700cx, 750mcx amp there at the factory, BTW, I have 4 fuses, well with-in the current capability useing a 30 amp breaker, as I said befor, I am not useing all the 30 amps!,however, This amp in particular spikes well above 20 amps while in use, maybe you should call krell, then you will get all the theory as to why this works properly you want, remeber, this amp at full power is 6,000 watts! |
Hi Jim, sorry, I just got back to this thread, yes, I have been listening, I do have a 10/3 romex connected to a furutech GTX-D Rhodium for my amp, yes, The Krell 700cx amp comes with a captive power cord that says 600 volts rating on it, Jim, I have said over and over, my amp is NOT useing all 30 amps, it simply spikes over 20 amps, all I am saying Jim-Jea48, My krell 700cx runs cooler, more dynamic, bigger sound stage, more or less, effortless useing a 30 amp single pole breaker versus a single pole 20 amp breaker, I was shocked after 20hrs of burn-in of the breaker at the difference this made, Damn Jim, this is the best cheap tweak ever I have done, more than cost effective, I do not know why or how Jim, But I assure you, the 20 amp breaker in my opinon, was chocking my amp!, Thankyou jim for all the post you have done, I really don't have an explaination, I am just telling you that this works, no problems, and was worth doing, and that I know many members of audiogon that did the same here with their Krell amps, I was afraid to do it Jim, Chris Vanhas of vh-audio sold me the furutech GTX-D R with the understanding that it would not heat up or damge the outlet with a 30 amp breaker because of how well it is built, as it turns out, he was correct, not even warm!, I have checked this outlet over and over, the wires going to it, if any smell was coming from it, for heat, nothing, the wpo-wall power outlet is cold all the time with NO issues, thanks jim. |
Jea48, one of these audiogon members that has e-mailed me for months about the 30 amp breaker is MRvordo, you can consult with him, maybe bring him to this thread, he uses the 30 amp breaker on his krell 750mcx mono amps, I believe a 30 amp breaker for each?, any way, every aspect of what he said this will do for my amp was spot on correct, he is one among many others that have done this with no issues. |
Jea48, Hi, believe it or not, I have $11,500.00 into my amp!, it is totally new out side nearly everything inside, however, I was shocked myself, I have no idea Jim as to why Krell used a inter power 15 amp wall plug on this captive power cord!, unless they were tring to save money,LOL!, the inter power I have is brass, ok sound for what it is, but you can see as to why going to a high end wall plug like the furutech FI-50 Rhodium that is overly built 20 amp would be a good idea, Jim, I talked to chris vanhause of vh-audio, he sells the 30 amp wall plug version of the FI-50, his words- why would you buy this?, the 30 amp only has a little bigger contact surface area inside, the side ways blade is for child safty or people that would try to plug this type of wall plug to a normal fitted wall outlet, their is NO difference in each one for sound or power handling., end quote, chris also told me he does not list the 30 amp wall plug version on his site, no need, the version he sales is cheaper and can handle a load that I have here for sure, that said, I believe krell also used the inter power 15 amp plug on my captive power cord because this will not make any difference useing a 30 amp circuit, I know you dont believe that Jim, however, I have no issues!, the wall plug does not in any way change temperture driving the amp hard, it stays cold all the time jim, like I said, I am only conterplating on this furutech FI-50M for sound purposses only because I have the matching wpo's-wall power outlet's, thankyou jim, I am reading into what you are posting, I do not disagree with you, but I am saying I have NO issues here with what I have set-up, I constanly check, cheers. |
Jim, I would have to e-mail patrick at krell, he can look into your request, or you may e-mail him, patrick bresnahan, very nice guy indeed,my amp does have two huge transformers jim,this thing weighs 180 pounds out the box!, jim, I have said that this amp is NOT useing all 30 amps period, it is spiking well above 20 amps, that is all, the 30 amp breaker gives the amp room to breath so to speak of instead of being choked down!, I believe my amp does have two 4KVA transformers, the so called breaker on the back of the amp is really a power switch, turns on the amp to stand by, I took a look at it for you, it says nothing on it or around it about amps, that stereo times review is a good one, should give you some info there if I recall Jim, and my recepticle is fine, it stays cold, no heat up or some kind of trip you specified, I learn alot from you jim, but for some reason, you believe this will not work, or does not work, please listen, this works wonderfully, sounds way better than a 20 amp breaker, I do know krell has told me it is a simple thing for them to change the power to 220 on this amp instead od 120 for u.s.a., I do not know if this helps jim, I do have a owners manual on this amp here, cheers. |
Jea48, another thing I wanted to say to you, first off, you have my respect, I bought this amp and refurbished it beyound oem because it is the last of the big iron of amps, it's the biggest most powerful stereo amp in krell history!, sure their may be better, I am thrilled with what this amp does jim, it's the kind I can ride off into the sunset with, I care less about the best next thing, very good sound is never absolete to me, sometimes, one needs to think about getting off the merry go round, do you believe that?, I do, tring to build something special here, krell already has informed me I am the only they know of with an amp like this that is modded, may not be the last to do all this, I do know this amp sounds hugely better than it did, all this took me two years jim, back and fourth this amp went to krell!, I have had it all complete as of december 2014, not very long at all,mated with tube equipment, it's magical sounding,cheers. |
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. |
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. |
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. |
I agree with Mrvordo!, he has the krell 750MCX mono amps with 30 amp breaker!, he knows first hand this works on our monster amps! |
