| Lyra Atlas SL Cartridge Magnet type?? @daveyf Neodymium is king when it comes to flux per uinit density but i believe the strongest magnetic field ever created was via field coil.as to whether different magnets sound different or by definition the strongest magnet type is best I'll a... | |
| Lyra Atlas SL Cartridge Magnet type?? daveyf Platinum magents are a thing and not some marketing gimmick. The Lyra Parnassus famously used this type of magnet and in order to get an Olympos beyond the original run of 10pc, a Parnassus donor was required for the magnet.dave | |
| Cartridge loading who is this "palmer" and can someone point me to the relevant posts of his regarding this subject?dave | |
| Cartridge loading Alas this article is not available online but if you go to the IAR website it states Issue #5 can be purchased. I got my copies off of Ebay when I was pointed to the topic.I said in proper design it is obviously possible to reach a neutral balanc... | |
| Cartridge loading Ok, so if by tracking problems at HF you mean attenuated HF then I agree. But this behavior applies to any damping, also purely mechanical, not only to electromagnetic.The first thing Moncrief does in his article is to do a frequency plot of the c... | |
| Cartridge loading Hey Ralph,this is where we got last time we had this discussion. Quite simply it does not need to! Audio energy can cause the excitation. A resonant circuit can be driven into excitation with a single pulse; it should be no surprise that on-going ... | |
| Cartridge loading I’m much more intrigued by @intactaudio dave’s observations of lowering the IMD. Have you tried plotting the IMD vs. R dependence?not yet. coming up with a concept for a test methodology to do this is not an easy task and then bringing that conce... | |
| Cartridge loading Mijostyn,The Hagerman site gives loading examples for what appear to be a typical MM cartridge where the resonances being damped are just outside the audio band. This discussion has been about MC cartridges where the resonance in question is typi... | |
| Cartridge loading Syntax,you mention cartridges sound purest into 47K and dull into larger loads and if your phono stage isn't up to it you are in trouble. Mocrief suggests (and then supports with data) that the "dull" sound reported from loading a cartridge is si... | |
| Cartridge loading I agree that the load effecting the compliance is a plausible explanation for part of what is happening with loading but when it comes to "work" and tracing high frequencies the water becomes a bit more muddled. It seems that moncrief pretty cle... | |
| Cartridge loading I did repeat the experiment with a completely different setup and my results paralleled Moncrief's. I would expect different absolute results with different tonearm / cartridge combos. I did see a pattern of behavior that was consistent with bo... | |
| Cartridge loading There is an interesting article in IAR #5 by Peter Moncrief titled "Audio Fallacies Exposed Low Impedance Loads for MC Cartridges" about loading and he proposes that loading down a cartridge helps it keep better contact with the grove. Moncrief a... | |
| NAGATRON HV9100 what needs to be repaired on it? I have one that also needs a new stylus assembly and have not gotten much past that. It is missing the cantilever and it appears as if the suspension has "dissolved" to give no indication where / how the cantilev... | |
| Stylus-Drag..Fact or Fiction? the time constant of the timeline is so long in relation to the music it can only show general speed and your experiments seem to show that stylus drag does indeed slow the platter. It is interesting that the TT-81 seems to correct for this "auto... | |
| Phono Cart Impedance Question If I had to guess, the broadband hiss is from a noisy tube gain stage and since it changes with volume setting tubes would be a good place to look. Check to see if the noise is the same type / level in both channels and if there are differences sw... |
