A question of loading...

"" certainly NOT on TRACKING which is demonstrably FALSE based on IM tests on tracking performance that I have incidentally performed as a function of load. ""

( He measured and is the only gentleman I know that did it. )

Pick-up your measures and come back to talk with Wyn. Btw, 2 years ago you had the opportunity to post in that thread but you did not do it.

You posted several times there ( two years ago. ) but when wyn posted what you are reading here you just " dead silence ", not even JC posted to refute Wyn measures and he posted at least one time in that same thread. That attitude from you speaks by it self more than thousands of words.

" that there were any white papers. But FWIW they aren’t needed;..."

well Wyn thinks different and he proved. You, as almost always just: bla, bla, bla, with out facts, exactly as two years ago. Measures is a fact .

Anoher anecdotal: at A.Porter place he was running his low impedance MC cartrige around 400-500 and when I listened to it ( I/O phono stage. ) I told him that something was wrong with and I suggested to change the load impedance to 100 ohms and the cartridge quality performance " shines as never before " ( this was the AP words. ) and yes : nigth and day change for the better.

Btw:  ""  The 'more dynamic the sound' bit is false though.  "

Don't claim/tell to me but to Ortofon and do the same with M.Huber at FM Acoustics. Not to me.

So not going with education huh?

A.Porter place he was running his low impedance MC cartrige around 400-500 and when I listened to it ( I/O phono stage. ) I told him that something was wrong with and I suggested to change the load impedance to 100 ohms and the cartridge quality performance " shines as never before " ( this was the AP words. ) and yes : nigth and day change for the better.

No doubt.

if inappropriate loading bathes the phono stage in copius amounts of high-frequency noise, it may start to distort (unless the designer implemented various techniques to make sure that this won't happen), and the result will likely be intermodulation distortion. ""

Apparently Albert's preamp needs that because

If the phono stage does not have high overload margin at ultrasonic frequencies, or not-so-favorable linearity at ultrasonic frequencies, the ultrasonic spike resulting from high-value resistive loads (the spike can be in excess of 30dB at 5-7MHz if the phono stage input termination is 10kohm or higher) can easily result in ringing and intermodulation distortion which will obscure real information.

Dear @daveyf  : As many of us I'm sure you know the Hagerman calculator  that's an old cartridge tool that explains several issues that J.Carr expanded and goes deeper than Hagerman.

As in the past threads here and in other forums everything is clear but the cartridge mistracking where Wyn measures and he was really emphatic:

"   certainly NOT on TRACKING which is demonstrably FALSE based on IM tests on tracking performance that I have incidentally performed as a function of load. "  "

All what JC developed was in order and learning white papers for any audiophile.

The  issue that's false is that  exist mistracking when more current running through the cartridge.

Any one of us can do/run a tests  with our today set up making load impedance changes ( and everything the same not touching any other parameter. ) and I'm totally sure that no one will dtect or find out a mistracking due to any of those individual load impedance changes.  

The test is not looking if the sound is better or not but if exist a mistracking or not. Obviously listening an LP tracks where we already know the today cartridge has no tracking issues.
Perhaps the only characteristic that we can detect could be that with 100 ohms or lower the SPL will goes a little lower or other characteristics not related with mistracking that is what we are looking for.

The test is not looking if the sound is better or not but if exist a mistracking or not.

This is complete and utter nonsense.
In 40 years of high end audio, including distributing and retailing high end audio back in the 80’s, setting up hundrededs of high end TT’s I have NEVER had mistracking due to "incorrect" loading.

The assertion is a fantasy. If the perception is loading down has cured mistracking, the listener must have the disease known as "cloth ears". Might want to consult an ENT specialist.

atmasphere :  ""   If what you say (that loading the cartridge has no effect on the stiffness of the cantilever),... ""

that's not what I'm saying even if I did not explain it in the rigth way.

What I'm saying is what i posted:


"2   stiffness to the cartridge cantilever enough to mistracking. ""

the key in that statement is: " enough ", this is what I'm saying and in his technical words Wyn too.

Two years ago here and in the other forum I told you the same: how much current has to pass through to stiffness the cantilever enough to the cartridge mistracking?

In those oboth forums I told you that for the mistracking could happens the cartridge compliance has to change a lot of compliance units and here in the Etna/Kuzma real example you need to pass from 12cu to 7cu to be out of the ideal resonance frequency range but that does not means for sure that will be a mistracking down there.

The issue is that mistracking not that cantilever stiffness. It's you who need to prove with measures that can gives the rigth answer to that question I made it two years ago and that you never answer.
