Jloveys, when you can measure a thing in audio, and also hear the same thing, then you have a powerful correlation that cannot be denied. Critical damping of any inductive device, whether it is a coupling/setup transformer, phono cartridge or tape head is an excellent example of such a correlation. Putting a resistor across an inductive device to effect Critical Damping is quite beneficial. Harmonic distortion is reduced, revealing more detail while simultaneously producing a smoother sound, and bandwidth is extended while simultaneously flattening the frequency response curve. These effect are easily demonstrated by measurement and listening tests. As an example I've included a link to the Jensen transformer website; Jensen is one of the world's leading manufacturers of MC step-up transformers (and other transformers as well; they have been in business for decades). On the page of the link you will see a pdf that can be downloaded that shows the various loading values to be used depending on the phono cartridge in use. http://www.jensen-transformers.com/mc.html Whoever you were communicating with regarding this issue is misinformed and missing out on getting better performance. |
Jloveys, that might be true on a track. But trucks are intended for use on the road, something that Formula cars suck at- their engines are not tractable since they are intended for power at high rpm. Additionally, many trucks will handle and ride better with a bit of a load... Do you see now that its not a good analogy? If you want to use cars as an analogy, an unloaded cartridge is like a car with no shock absorbers- it will ring (bounce) and oscillate with any input. A loaded cartridge is like a car with tuned gas shocks- the output will reflect only what is on the surface of the LP. |
My post was only the exact answer that the designer of my phono preamp gave me because I was curious that the load phono is not matching with the cart. The entire phonopreamp was build with that cartridge in test, and when I hear the result it is quite amazing, dead quiet, detailed, dynamic and I realy don't see how to do better.I am no audio engineer but I am very fussy about s high quality of sound in my system.. Tron is equivalent to Tom Evans in england I heard both and like both. TW Acoustics (Raven TT) use Tron as reference. So I think that Mr Tricker is a respectable engineer and what he says must be taken with consideration. Even if what he says doesn't match with your audio preconceptions it might be interesting to see why he says that load with tubes is less important than with SS. And why his phonopreamp is sounding so natural. Like music. |
