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?

In 2018 thread where wyn posted and before the first wyn post you posted not one but twice:

""" When you load at a very low value (like less than 100 ohms) its possible to reduce the cartridge output and also decrease high frequency tracking abilities. ( Btw, wyn runs his mandake at 60 ohms and performs fabolous. Obviously no tracking issues. )


"" the cartridge is asked to perform more work as it has to drive the lower resistance. This makes the cartridge cantilever stiffer and less able to track higher frequencies. This is why the resistor can act as a tone control. ""


Curious that in that thread that after the first wyn post there you left alone almarg ( who was supporting you. ) and you did not post nothing again about that cartridge tracking issues not even when wyn posted was FALSE because he measured.

In the other side and in the Etna/Kuzma resonance frequency it needs 3 compliance unit to change its frequency resonance and instead of 12cu we need 10cu. Again how much current is need it to happens that?

Instead 12cu we need 9cu. Frequency pass from 10hz to 9hz that's not enough for the cartridge been affected in its tracking abilities and the tonearm/cartridge behavior is not altered.

Other curious things that happened with you in those threads in 2018 is that in both threads JC participated and in both threads he not supported with a post the conversation you said took place in Munich when talked about that low load impedance consequences. Weird.

Curious too that JC even that he participated in the Agon 2018 he posted nothing when wyn posted FALSE about tracking.

Such is life.

I think is enough. If we learn something through this thread good and if not maybe helps to confirm what we already knew. All we win and no body defeated.

@rauliruegas  I have played around with the loading on several different MC's in the past..the results were not anything that could really be anticipated. BUT one thing that was never in question, was that the cartridge was mis-tracking in any way...which IME is very easy to hear! 
With my current Lyra, the tracking is spot on and is certainly not effected by the load applied at the phono stage, YMMV.
My hana el sounds its best at the recommended load of 400 ohms or close to that. Its currently hooked up to the Jensen sut which presents a 430 ohm load. Also perfect for my denon 103. My other sut is a rothwell with an effective load of 100 ohms, perfect for my other mc cartridges such as my goldring eroica lx and ortofon quintet bronze. I only use 47k ohms for my mm cartridges such as my 2m bronze or my om10 super. However, my phono preamp is of course currently set to mm at 47k ohm to accept the sut input.
Dear @daveyf  : Yes, any cartridge can't track the LP grooves in precise way but not for the loading but because all imperfections that the analog alternative has. Pivoted tonearms does not helps but increment the tracking problems and the LT too.

There are several threads where we discussed all what is happening down there at the stylus tip during playing and it's " terrible " for say the least.

MC are almost immune to impedance loading. Problem is not there, but yes a cartridge always performs with mistracking but if we can detect the mistracking in the cartridge play behavior then something is wrong in the overall set up or the cartridge tracking abilities are poor. Again, loading is out of that mistracking.

Even with all the analog alternative imperfections I know we have a lot of fun with or at least we are accustom to.
