A question of loading...


I have just replaced my aging tube preamp with a new model. When I was using my older model with tube phono stage, I would run my Lyra Kleos and other MC cartridges with a load of 750 ohms. So, I assumed that with my new tube phono stage, which also utilizes a transformer in the phono stage and is also built into my new preamp, that the same cartridge loading would apply. I listened to the Kleos for about a week with this loading, and frankly, while it was fine, I wasn’t bowled over. Tonight I decided to experiment, so the first thing I did was to run the cartridge straight in, with no loading plugs. WOW, the increase in overall musicality and soundstage width was eye opening! Lesson learned is that not all gear is going to react the same when it comes to cartridge loading, particularly if there is a transformer involved and even if you are using the same cartridge from one phono stage to the next! An eye opener, anyone else experience something like this?

Dear @daveyf  @fsonicsmith  and friends:  Why I don't took in count before:

in the thread where J.Carr shared his white papers ( load impedance/capacitance/inductance. ) and where he posted 6-7 times and in the Agon 2018 thread I mentioned J.Carr not even did mention about that cartridge mistracking behavior but he no where in any thread and certainly not in the WBT one J:Carr never mentioned not even near about that " increment of clicks and pops " ! ! !   GO figure  ""

That " clicks and pops " is a big and false tale/lie/disinformation/fraud or just name it as you want it.

Additional to that does not exist all over the internet any white papers about both subjects. DOES NOT EXIST NOTHING AT ALL ! ! !  No measures of any kind about even that in the two other threads and in this one some of us asked for and he just as always: dead silence because has nothing in hand that can prove it. Period and I mean it.

It's incredible to been discussing seriously both subjects and no one exist ! ! ! 

Next info is what J.Carr posted about the consequences that we can read in his white papers:


""  As most phono stages are designed are right now, the input resistor needs to serve two functions. The sonically dominating function is to make sure that the resonant ultrasonic spike isn't so large that it affects the behaviour of the phono stage. The sonically lesser function is to load the cartridge. I would like to see these two functions separated so that we can start discussing cartridge loading in terms of what it does for the cartridge, rather than as a phono stage band-aid in disguise.

How heavily contaminated (or not) your audio system's environment is by conducted and airborne noise in the frequency-peaking bands will also play a role.


 if some electronic component in your house is producing RF, this could preclude you from using higher resistive values for loading.  """



Now I can really laugh of that biggest audio " tale/lie " in the all audio history and now I understand why JC don't supported that man and his " tale ". Pity for say the least.

Raul-you are quite the enigma. Sometimes it seems that you are arguing about things that you falsely perceive the rest of us are arguing about-but aren't-and at other times you seem to misunderstand the entire topic. We can be talking about the weather and you start talking about the meaning of life. You probably will misunderstand my analogy too. This might get hilarious. 
Even your signature line is grammatically flawed. It should be "Enjoy the music and not distortion". You are missing a critical word "and" and you have erroneously applied the plural to the word "distortion". And this is before I get to the fact that your premise that music can be recreated without distortion is fundamentally flawed and your apparent belief that some people only enjoy the [inherent] distortion to the exclusion of the attendant music is also absolutely flawed. 
I am willing to bet you would be a great guy to have a beer with in person but your online persona is so clouded by your poor grasp of English that things go sideways fast. 
@fsonicsmith Let’s give Raul some credit here. He is posting in a foreign language about technical issues that are somewhat difficult to extrapolate on even if you are fluent in the language. I appreciate the fact that Raul clearly is one of the more dedicated audiophiles here- and while i may not agree with some of his posts, I do think he contributes points of interest. I know that if we ( natural english speakers) were attempting to do the same thing in Raul’s native language on a foreign web page, I seriously doubt we could make ourselves understood as well as he does. ( even if we have to translate a little in our minds as to what he is trying to put across..:0) ).
Dear @fsonicsmith  : At least I'm not a lier. Thank's for your post.

Last night i decided to do a little more experimenting with loading. I had felt that the change from the 750ohm load to wide open ( presumably 47Kohms) was beneficial. The sound was like I described in my OP. However, over more time, I was hearing a very slight increase in brightness on wind instruments, particularly trumpet. Since it was suggested in my preamp manual that a load would be beneficial to reducing any kind of brightness in the cartridge, and that a load of 300ohms was a great place to start, that is what I did. Sure enough the minimal brightness was no longer a factor...and the soundstage benefits i had previously heard were still there! So, for now, 300ohms is where I am at.
