Who needs a MM cartridge type when we have MC?
Roy,What a nice, clear explanation - an excellent contribution to this thread and to understanding of tonearm/cart interactions. I agree it makes perfect sense (again, to me). I had certainly left out the aspect of sub-10Hz resonance, partly becau...

Griffithds, you have to thank In_shore for the warning about the Phantom and the Empire. I have never tried the pair. 
Who needs a MM cartridge type when we have MC?
In_shore,The EPA-100Mk2 I had rebuilt/modded was in pretty terrible cosmetic condition, and the VTA ring had come unstuck, and it had cigarette smoke residue gumming up the bearings slightly. I had the arm completely overhauled/cleaned, some of th... 
Who needs a MM cartridge type when we have MC?
Dear Fleib,I understand the way a stylus moves in a stereo-cut groove and the way a cart body moves across the record. I understand the definition of MOI, and I understand the weakness of the wiki definition as it applies to the stylus end of a to... 
Who needs a MM cartridge type when we have MC?
David,You and I obviously agree on the physics regarding the principal 'reason' suggested above for why longer arms are 'worse' than shorter arms. The 'head' of the tonearm is NOT supposed to be 'responsive' to the cart's nano-movements. I also ag... 
Who needs a MM cartridge type when we have MC?
Dear Fleib,I am not sure what you mean by 'time constant between bearing and stylus'. Is it measurable or definable in any way? The headshell of a long arm takes exactly the same time to move from outer groove to inner groove as the headshell on a... 
Who needs a MM cartridge type when we have MC?
I stipulate the following points and conditions:1) there is no PERFECT arm.2) Some arms are better than others (they introduce less distortion into a system) with a given cart.3) when discussing a 'better' design WITHOUT KEEPING OTHER FACTORS CONS... 
Whats on your turntable tonight?
And spinning now is 'Friday Night in San Francisco' by John, Paco, and Al. I love this record! 
Whats on your turntable tonight?
West Coast Blues by the Harold Land Sextet (listening to VIJ-4080, which is a Japanese pressing of JLP 20)On deck is Sonny Rollins' Way Out West (CR S 7530), followed by a Japanese pressing of Chet Baker's 'It Could Happen To You' (VIJ-4068), then... 
Who needs a MM cartridge type when we have MC?
Dear Raul,If we filter out everything you said about AHEE and the rest, what you are saying is that..,1) the stylus-end of the tonearm is supposed to 'react' (i.e. move) when the stylus is moving. If the stylus is moving side to side, then the 'pe... 
Who needs a MM cartridge type when we have MC?
Fleib,I am not sure who is the "many" who "feel" that between 9 and 10.5" is optimal. I would be interested in understanding the math of why they may feel that way though...If we assume, for a second, that the record is stamped correctly (around t... 
Who needs a MM cartridge type when we have MC?
Raul,Could you explain why a longer arm - one which is 10-20% longer than a 10-inch arm - necessarily increases 'distortions of every kind'? Is it that the longer armwand necessarily increases distortion based different/increased resonance? Also, ... 
Who needs a MM cartridge type when we have MC?
Hi Jonathan,I think the MC-L1000 is quite decent already. I would agree about the VTF sensitivity but given it's construction, it really isn't surprising. Been there done that with the head amp - the combination is wonderful. Going to be re-mounti... 
Who needs a MM cartridge type when we have MC?
Jonathan,Thanks very much as always. The literature I have seen says the MC-1S (and X) had an air core. Were there any others besides the Victor and the MC-1S (and -X) which had similar printed coil construction? 
stepped attenuators
I wonder if they changed over time. My JP80 is ancient (s/n 008), has a single volume pot and a balance knob, neither of which are stepped.
