Rewiring Klipschorns

Recommended Posts

 Hello, 

 

 From late Q4 2019 on, you and any of your friends would always be warmly welcomed, and it would be fun to meet you.  

 

I have my VOTTS set up,  ( A7-8s)  after several years, finally,  to where I am happy with them, and the new KT88 DC SE amp looks like it will have me quite satisfied. 

 

I have work to do , to have friends listen.  I need to repair my System Attenuator.  Priority number one.

 

I then have to replace a broken Phono RIAA EQ, with something decent, that I can afford.  Maybe build one. 

 

I have a decent turntable, arm, and 13 Fulton ( conical stylus  ) moving coil cartridges.  What a shame,  over 10.000 L.P.s,  but a unrepairable RIAA EQ !!  

 

Been using the top-of-the-line Pioneer BDP-09FD Blu-Ray player, which is decent enough.

 

You stated this as an idea :   " We need at least another individual, perhaps more than that. "   I agree, but its not always  easy to A-B things.  ( If it is BLOWING you away, there is less need to A-B or to prove - anything. !! )   Look what I put together, about a week or two ago, where we all went to Montana -  just to hear audio gear, amps mostly.  

 

                     https://community.klipsch.com/index.php?/topic/185504-montana-directly-coupled-2a3-amps-versus-missouri-kt88s-in-sepentode-zero-nfb/

Yes, I saw that.  I see every post on every thread, believe it or not.  Just to state it again, I'm not here to embarrass you or anyone.  My ears aren't what they used to be, and I'm in my early 50's.  I know I can't hear certain things anymore.  I believe there isn't any magic or witchcraft or quantum effects in any of this.  I believe that any differences in an AB test should be measurable with standard instruments.  I'm intrigued by your claims of hearing things that make others lose their minds - just from the claims!

 

Mark Waldrep has said (and I believe him) that if you AB a tune with a louder version of itself, most people will chose the louder one as better.  This doesn't say which one is actually better.  Better is itself a subjective term.  So let's not get into "blowing you away" comparisons.  Let's stick with, say, wire.

 

I contend that neither you nor anyone else should be able to consistently and definitively hear the difference between these wires:

 

57 1/8" wire vs. some other length, say 60".

 

Standard wal-mart 16ga zip cord "speaker wire" vs. a coat hanger.

 

If you can, I should be able to measure that "something" in amplitude or phase or impedance or capacitance or some combination.  My guess is that I could "null test" the wal-mart wire vs. the coat hanger without a person in the loop and the difference would be zero.   

 

We cannot have a day or even hours between tests.  The test switching must be near instantaneous.  Let's figure out what that looks like.

I hope you have a day job or, a rich wife!! (both would be nice too!!)

 

:emotion-19:

 

 

Yes, this is a life-long hobby and passion for me,  have a day job, but best of all, I finally found the solution on amps.

Inside an a DIY amp I am constructing, one can often hear the difference between one inch of 16 AWG versus the use of 10 AWG for that same one inch span. 

 

I find that to be an incredible statement considering the poor quality soldering I see in your builds. The lousy solder joints likely cause far more audible degradation than the few milliohms difference between wire gages do.

 

I see you use a soldering gun for your projects. So did I when I was a high school student many years ago. I have since learned that a controlled temperature soldering iron with interchangeable tips yield the best results; Temperature controlled soldering equipment is required by NASA, and soldering guns are specifically prohibited.

I may be a little off topic here, but below is a picture of my Klipschorns upgrades with the Western Electric wires and other upgrades that to me takes a great speakers and takes it to the next level.

Its on topic !!  One of the few on topic posts in this thread that is.  Thanks for posting it for all to see.

 

I MAY try to get a shot of mine, with 8 AWG and 16 AWG  m22759/11 wire. 

 

I avoid polarities to touch each other, thats audible on my rig, and others'.

I am pretty sure you can not go off topic on your own thread. You are the OP, have at it. In my opinion, your post was the most on topic in many pages.

Have fun with your thread. There should be some helpful info hidden in here somewhere.

You, and your supporters, are sorely mistaken.  You saw my earliest use of a Soldering Gun. It got better as I gained practice.  For the wires I use,  my ( or any I know of ) temperature controlled soldering station is not powerful enough, and it does not work - at all, to do what I want .  Ninety percent of the time,  I use a 325 Watt device now - to get it to do what I want, not what NASA wants !!

Hi Tom,

 

 

Yes, about 40 years of hearing wires,  building amps and some speakers with different wires, and hearing what it does when incorrect and correct.

 

 

Jeff 

So it's all your subjective opinion in other words?

 

Fair enough, that just means it will vary from person to person.

I was referring to the KT88 build from March of this year.

Well, I have used a Weller WCTPC 60 watt production soldering station with an 800 degree chisel tip to solder 12 gage wire to the inside of a 1/2 inch schedule 40 stainless steel pipe. Previously that job had been done using a propane torch, so... I'm pretty sure that soldering station could solder any wire you have used in amplifier builds.

You brag about using MIL spec wire, yet you do not use MIL spec tools and standards to solder those wires in your builds. Got it🙄

Absolutely.  Different people will have different levels of audio listening experience, with different gear over their lifetimes !!

Maybe you should show us a graph of your hearing range within .1db.

That basically means that anybody can say anything on any audio related subject and it can't be proved wrong because they say that it's so.

So was I.  I ordered a Weller D-650, current model, 300 Watt, for thaqt KT88 build.   I had not used that before, so I had to learn how.

You are discussing ONE non-audio solder joint.  How about a whole amp ?? 

 

Don, for a ground run, I was regularly using not one 12 AWG wire,  but instead, using 12+12+14 AWG in parallel, and later, midway through the construction, went to a single 8 AWG run ( better sounding !! ).   The photos of that are in the KT88  " interrupted " build thread.   I am very sure that WCTPC is totally No Good at all, for my use.  I think I even have one .

Wait a minute, I don't " brag " about using Mil Spec wire at all !!!   I offered it freely up here for people to try.  Why, Its the most cost effective wire, well made, I have found to-date in audio. 

 

READ what Steve Deckert says about his use of that over the last 20 years !!   But one need not spend $450 for four ten foot lengths to do stereo from a Manufacturer - reseller.  I did the math and showed you how to do it ( DIY ) for under a C-Note !!   

 

If I bragged, it was about finding the most cost effective wide-band wiring I have ever found, and suggested use of it in 8 AWG to the Klipschorn , from the amp, 8 AWG to the midrange driver, and certainly  8 AWG to the 15 inch.  16 or 14 AWG to the tweeter, from the crossover.    

 

If a person had a really good tube amp on a Klipschorn, this 8 AWG m22759/11 wire suggestion of mine will seriously outperform  all 16 AWG Dueland or WE wire !!  

 

Do you understand me a little better after I clarified your misconception(s).??  Hope so.

 

Have fun, I do.

Right sir, and thats what occurs on Forums. 

 

It is the reader's job to discern what the posting person's background is, and to what degree they want to pay attention to any poster.

 

Unlike many, my information is posted up here, starting with - a Moniker under my full given name, photos of my high efficiency speaker set up, and (on my Member's page ), my complete HISTORY in audio, from the time I came home from the hospital, and my Mom was nursing me to an original ALTEC 604, with WOR ( New York City, FM station- classical  ) playing in the background.  

 

 I often wonder, what are the qualifications of people who post up here, their experience,  and better yet, how good would their home Hi Fi sound to me?? . 

 

My information has given rather thoroughly.

Soldering, 8 AWG equivalent wiring.  For highest instantaneous pulsed current delivery to the speaker.

What occurs on forums is that a few people decide to post opinions with no basis in fact or science.  It's easy for members to spot said posters.  Normally controversy surrounds their threads and posts for obvious reasons.  Sometimes threads get locked, some times posters are banned.  That's what occurs on forums.
