Krell 700cx, and Tara cobalt A/C power cord.


I have used many times in the past after market power cords with a Krell amp and result with a sound that was worse than the stock cord from Krell!, I am getting ready to send A Krell 700cx back to Krell to be renewed for me to last!, The amp is only 8 years old!, It came hard wired with a snake of a stock power cord!, My question is will a retail $5,000.00 Taralabs cobalt A/C power cord sound awsome with this amp?, My friend Jmcgrogan2 is telling me to get Krell to put an IEC input on the amp so I can use an after market power cord, I have extensive experience with Taralabs cables and know them very well!, However,I have never used a cobalt on a Krell 700 cx!, Will this work?, who has done this?, what was the sound out come?, Thankyou!

@ Pantera6, that would be a 15ft power cord in my case, my captive cord is 9ft long.
@ pops, Thanks, The Taralabs cobalt A/C power cord is defiantly going on the Ayon digital player!, I am getting ready to call krell now, I will let you know what they say. cheers!
@ pops, Thats funny you said stay put on the carrol power cord made onto the amp, I talked to Ray, The service manager at Krell, LOL!, They do not recommend after market a/c power cords for the 700 cx at all, and will not warranty the work performed on the amp if I use one!, It really sounds very good to me with the stock ac power cord eanyway!,, I hope some one out there in the audiogon world comes on this thread that has used a Taralabs cobalt a/c power cord with a Krell 700cx to very good effect!, cheers!
Does anyone have any exsperience with after market a/c power cords with a Krell 700cx amplifier?,, cheers!
Please, If eanybody can help, I would be grateful!, Is there eanyone ever used a after market a/c/power cord on a Krell FPB 700CX?, cheers!
@ Rondel,Hi, have you the experience of adding an after market a/c power cable to a Krell 700cx?, Thankyou.
@ Mrvordo, Hi, Man, I was really hopeing you got back to me, Thankyou for doing so, your theory is exactly what I already believed!, I also agree with your whole post!, I was believing thats exactly why the electrical stores were saying what they said, LOL!, they said the same thing you did!, Krell told me to use a 25 to 30 amp breaker, The electrical supply houses said It would not work, I knew it would!, They said it was not code to, and I would be taking a chance on damageing my amp, and a possible fire could happen, Krell did say the 700 cx would run smoother and cooler!, can you hear a difference in sound with the 30 amp breaker alone??, thats one question I would like to know, Thankyou, cheers to you!
@ Nglazer, Hi, I believe the captive cord sounds good too, one of the members thought that my Krell 700cx might sound better with an after market a/c cord,my experience with after market cords with krells sounded worse than the supplied krell cord!, The captive cord on my amp is 30 amp carrol 10/3 power cord, Krell has my amp right now, they are making it brand new again for me, its only 8 years old, krell said, before they send it back, they wanted me to change my 20 amp breaker to 25, up to 30 amp breaker!, The Audience AR^ power conditioner you have might not work on my amp???, my amp draws 6000 watts full power, but of course we do not ever get to that point, close, we like it to shake the house from time to time,LOL!, It seems no one here on audiogon has used an after market power cord on a krell 700cx!, you are the closest to an answer I have gotten!, I thankyou very much, I do have a 10/3 electrical cord in the attic running to the receptical for the krell I have, If you believe the a power conditioner can work on a powerful amp like this one, let me know, and I will look at the specifications of the power conditioner to make sure it can work!, Krell says, of course, that their is no conditioner that would work for the 700cx!, I am open minded to eanything!, I just have to know it will work,, cheers!
@ Mrvordo, Hi, Thankyou, This is some help, you are the closest to what The thread is about, did you have any problems with doing so?, your krell pulls some seious current!, My amp is very similar to yours, thou they sound different.,, cheers!
@ Mrvordo, Hi, I have went around and around with the electrical parts houses, they do make since thou, and I understand what they are saying, so, I will tell you, the electrical parts houses say, In no way can you run a 30 amp breaker to your amp!, I asked why?, they said that all american recepticals for the home for 110-120 are maximim 20amp, therefore you cannot use a 30amp breaker on a 20amp receptical, they said it would damage the amp and melt the receptical likly..,,,, Now my question to you is, how did you or how can you use a 30 amp breaker on a 20 amp receptical??,,, Krell said to use a 30 amp breaker on my amp to, untill I told them that all recepticals are 20 amp, krell then said keep my 20 amp breaker in!,, needless to say, I am confused here!,, As far as recepticals, I have a 10 gauge 30 amp electrical 3/1 wire going to a 20 amp receptical now, I am changing the receptical to the best built receptical I know of, It is berlinuim and very thick copper metal, all the metal is thicker than all the brands and models I know of and it is cryo treated!, They come from melbourne, Australia,, many, many audiophiles say this receptical out performs the ps audio power outlet that you are talking about, I will look into the wattgate you have, I have studied the recepticals for a very long time now, currently, the receptical from Australia is the best I have ever seen!, another thing is, your power cord is 20amps as well, how is that going to work with a 30 amp breaker?, The captive cord on my amp is a 30 amp power cord, It says 30 amp on it,, cheers.
@ Isochronism, Hi, No, I have not looked into Coconut power cords, However, It may not be the very best, I just bought a Taralabs cobalt with oyaide plugs back on june 28th to go on my source, it is a 20 amp power cord, I do believe there is no better power cord from the $9,000.00 class on down, my opinion only, what do I know, right!,LOL!, I have not even used the cobalt power cord yet untill I get my amp back from Krell.,, cheers.
Mrvordo, You talked me into to it!, I am going to run my Krell like you!, I mean, how different can our power grids be from each other?, Like I said, krell told me to do what you are doing!, A 25 to 30 amp breaker,man, If its a 5% improvement, Its worth it!, A breaker only cost $15.00 to $25.00!, This does Help!, How long have you been useing this set-up?, and you have not seen no problems?,, you are one of many people that told me that they were doing this on the audiogon, cheers.
Hi Mrvordo, I will take your advice on getting a good outlet first, more than 5% up-grade in sound is great news, I believe you, I did not know the result in doing this would yield such great results, You have been alot of help, thankyou, I still like to talk more with you, tell me of your system, cheers.
@ mrvordo, Man-o-man, what a killer set-up you have, the room, the system, etc..awsome to say the least, congrats are in full order here!
Mrvordo, that is cool, over the top that you built your own cross overs!, sad news here, I do not have a pre-amp period!, I use digital source direct to amp, just started building this system in april, 2012,,,, I may or may not go to a pre-amp, since 1997 I have been running the high-end this way!, source to amp, very spooky clear, I love analog, to get the matching i/cs and a pre-amp, and phono pre, and a phono cable, mmmm that would be $60,000.00 for real for me, can not afford that now, my interconnect retailed for $15,000.00 a meter, can you imagine buying two more pairs of them and everything else that I listed, I would need a $10,000.00 pre-amp or more to better the source direct to amp, in due time I may go this route, buying a piece at a time,LOL!, not today, I just sent the Krell 700cx to krell to be totally renewed in and out, it was only 8 years old,It was already in mint condition when I bought it used, april, 2012, thats costing us $3,157.00 to do this, I have been spending my lifes money totally on this system as it is, every 3 to 4 months, something else, I just bought the Taralabs cobalt power cord with oyaide plugs june the 28th, 2013,, it retails for $5,450.00 for 6 foot, I will put that on the source, I wanted to use it on the Krell, the krell has a captive carrol 3/1 30 amp power cord on it, from the factory, they made the cx line like that, I asked krell about changing that out to iec, they did not recommend that at all!,, how do you like the phantom 3?, I have conterplated going to a krell pre-amp!, I like tube sound alot to, thats my sources I always use, currently I have a Ayon 2s player, I may keep this, if I do I will use it on a second system, it has the best transport I have owned, I have started looking to go even Higher end than the player I have now, This player was $6,350.00, I want to see what alot more money can do or not do, this search will take a while, I have got four brands on my list so far, Ayon, Esoteric, Aesthetix,vincent.., some of these players have analog pre-amps built in the cd player!, this also keeps cable cost down, you know what I mean?, I am very interested in a few pre-amps to, Krell is defiantly one of them, How much was the phantom 3 ?, cheers.
Mrvordo, Are you there, you must be listening to some music, when you get a chance, get back to me, Happy listening.
@ Mrvordo, Hi, I have a ways to go on building my system, you already have a magnificent system and room, congrats!, you have helped me here with this power set-up, thankyou very much, cheers to you.
@ Pantera6, Hi, Thats interesting post!, you are saying you kept the stock power cord on the unit, and added a female plug at the end and used a aftermarket power cord?, wow!, thats a very long power cord, Why did'nt you put an iec connector on the amp, and then use the after market power cord straight from the amp to the wall receptical?, I asked Krell about putting an Iec on the amp, of course they said they did not recommend that because of my amp being a 700cx, I really would love to use my Taralabs cobalt power cord, that has oyaide plugs from the Tara factory, on this amp, My captive power cord on my Krell is a 30 amp cord, I do not believe their is a 30 amp after market power cord?, your post is very informative!, cheers.
@ Pantera6, Hi, Your last post was a great write!, I believe I said Krell did not recommend putting an IEC socket on my amp,But they did not say they could not do it, and they did not say that would not do it if I asked them to, why don'nt you get Krell or sombody else put a IEC socket on the amp, I know Krell can do it to cosmetically great effect!, I am finally sold that a super high quality power cord can improve the sound of my amp, I did buy a 1-year old Taralabs cobalt power cord with oyaide plugs last june the 28th, it is 3ft long, this power cord in a 6ft version is retail $5,450.00,, this would do the trick for sure if I can get enough balls to try it on my amp, the power cord is 20amp with 20 plugs, MRvordo did it with his fpb 600 he has now with no issues, I do have a dedicated circuit and electrical cord just for the amp now, what you did with your power, I did in 1997, yes!, It improves Krell amps substanially, The difference I did however, was to run a very short ground to earth, with a real copper ground rod, less than 6ft was how long the ground was, talking about a very huge improvement!, I'm still working on that here thou, warning, when you use a dedicated ground like this, BTW, Krell factory does the same thing, It will not flip your breaker if you incure an issue!, thats the drawback!, If you are like me, I unplug the whole system when I am not useing it eanyway!, there is no worrys this way, LOL!, Pantera6, My amp is still at Krell now, we have 6 weeks and she will be home, Krell has been done with the amp, They were kind enough for us to make payments on the amp being totally renewed inside and out, at cost no object!, I wanted to have the countrys very few, if eany?, Brand new FPB 700CX amp!, Krell guranteed this to be brand new in every way, Krell said, with what they have available now to go in the amp, Its likly It will sound alot better after the break in of 600 hours than it ever did in the amps life time, mmm, needless to say, I was Thrilled to be told that!,BTW, I love your user name, It reminds me of one of my all time favorite metal bands, Pantera!, The thing is, I could get Krell to do the IEC socket there at their factory, I do not believe we can afford it, I know that sounds awfull funny!, But we are paying them $3,157.38 now!, I will have a little over $11,000.00 in this amp!, I know I will never get my money back out of it, we plan to use it one way or another on one of our systems untill it dies!, currently, its on the main system for the next few years, untill I can get my hands on a Dan D Agistino amp!, this Krell 700cx was made in 2005, It was not even needing an overhaul yet, thats ok, we will have a new one, I am sorry fellas, I am very proud of that! cheers.
interesting Mrvordo, thankyou for your response, what does all of this retail for each?
Hi,, Your post needs to be on the thread, cables more hype than value!, there will be alot of disagreement there for you!, this thread knows the difference cables will do to any cost componet!, the unfortunate thing here is everyone on this thread has very,very, exspensive componets they are useing high-end cords and cables on!, they are very happy, and have no regrets!
Hi adri2005 , who and where did an iec for you,  krell would not do it, Thankyou.
