MC for Low Mass Tonearm
Add some mass at the headshell and use any MC you want. You need not take the perfectionist approach. Also, have SS retip your F9E with their OCL stylus on a Ruby cantilever and you may not feel the need for an MC cartridge or a SUT.  
Lyra and OMA
Michael, a few postings ahove you wrote something to the effect that the higher the effective mass, the higher the resonant frequency. Actually, it’s exactly opposite. Resonant frequency and tonearm effective mass are inversely related. So a highe... 
Lyra and OMA
11Hz should be fine for the calculated resonant peak. Keep in mind that you’re using parameters (compliance and tonearm effective mass) that are good guesses at best. Fortunately there is a lot of plasticity in the equation itself as well, since i... 
Lyra and OMA
Many tube based MM phono stages use 12AX7 as input gain tube. 12AX7 has high Miller capacitance, so I don’t know how you’d defeat that . This has been going on for decades(mating a SUT to a 12AX7 input). Do you see it as a real problem?  
Lyra and OMA
Do you have any idea who actually make the OMA SUT?  Typically, OMA collaborate with other companies to manufacture equipment they market under their brand name.  Also, what is the turns ratio, which determines the voltage gain, of the SUT?  
Second MC Cartridge Choice.....Tokyo
Yodibashi Camera in the Akihabara district of Tokyo sell MSL right off the shelf.  Last time I was there, they had a wide array of MSL cartridges in stock.  They also discount the Japanese VAT and give an additional discount for using a CC.  
Pioneer PL630- upgrading the phono cable?
Ghd, how can you say in the same post that you never heard a difference among phono cables and also that you’re a big advocate of carefully choosing interconnects, etc? Seems internally contradictory, especially since a phono cable might be expect... 
So Weird- No Stylus Contact Woofer Pumping with Hana ML and Elac PPA-2
DC has no "rise time", by definition.   
Discuss The Viv Lab Rigid Arm
Yes, everyone knows what you think. Does your disdain apply to the very idea of an underhung tonearm or only to the Viv Float, which is a bit eccentric in other ways?  I wish someone would market an underhung tonearm that is otherwise conventional... 
Stepping Up From A Graham 2.2 On A Basis Audio Debut Deck
The Walker is definitely designed to supply AC TT motors.  However, if you already own it, and if the Basis motor is DC, I think you still can benefit from it if you just set it to put out the full 120VAC.  It normally controls speed by reducing A... 
Discuss The Viv Lab Rigid Arm
Less than zero overhang.  Underhang.  
Discuss The Viv Lab Rigid Arm
Raul, I think you are talking about making a calculation and Dave is talking about geometry.  The point is that in order for any pivoted tonearm to produce two null points on the playing surface of an LP, there MUST be overhang AND the headshell M... 
Help me understand cartridge alignment
Clearthinker earlier brought up a great point about zenith errors in the fastening of the stylus tip to the cantilever, which of course is done by the manufacturer. This came up in the other long thread on the Viv Float tonearm. Apparently, Ogura,... 
The Mood Was Ruined
Maybe you should stick to digital, if vinyl is so painful for you. I quite agree with you that DD turntables get piano right, whereas some of the other TTs that use other drive systems don’t. Anyone else’s turntable excepted. (Note, I am leaving h... 
Stepping Up From A Graham 2.2 On A Basis Audio Debut Deck
If you have never had the benefit of a motor controller before, you will be very pleased with the Walker, whether or not the Phantom is a revelation, though I suspect that it too will make you happy.  I would have thought that Basis provides a mot...
