Koetsu cartridges - myth or reality?
My point is that the effective mass of the tonearm is largely governed by the mass between the pivot and the stylus contact point. The CW is on the "other" side of the pivot and I don't think makes much contribution to effective mass. I saw a disc... 
Koetsu cartridges - myth or reality?
Dgad, I think the point is that one can alter the effective mass of the DV507 in the vertical plane, by using headshells of different weight mostly. I am not sure about iSanchez' idea that changing counter-weights has much of an effect on effectiv...

Cool! Thanks. 
Koetsu cartridges - myth or reality?
Dear iSanchez, I read the URL you posted on the DV507. Your post above Sirspeedy's last one missed the point of my question. I am wondering about tonearm effective mass as it relates to cartridge resonance, and you wrote about counter-weights and ... 
Koetsu cartridges - myth or reality?
Genesis and others who recommended Dynavector 507 with Koetsu: The Koetsus are relatively low compliance cartridges. The DV507 is said to be a "high mass" tonearm, but just looking at its unusual design, it would seem to have low mass in the verti... 
In love with my Loricraft
Sorry for the apparent "tone" of my post. I really was only curious to learn about the Loricraft as it might be compared to my VPI HW17. The HW17 also is bi-directional, and the cleaning fluid can be dispensed either from the storage reservoir by ... 
Koetsu cartridges - myth or reality?
Thanks. The virtues of the 507 are similar to those of the Triplanar, as regards azimuth and VTA adjustment, apparently. 
Koetsu cartridges - myth or reality?
Raul and others, you have made me interested in purchasing a Dynavector 507 in order to max out the performance of my Urushi and future Koetsus I may want to own. I have never seen a Dynavector "in the flesh". Does it have provision for azimuth ad... 
In love with my Loricraft
So, apart from the noise reduction vs a VPI, what are you in love with? What else makes the Loricraft functionally superior to others? (I clean records in my basement workshop, where noise is not an issue, and I don't try to talk on the phone whil... 
Koetsu cartridges - myth or reality?
If you don't want to spend the bigger bucks for the Koetsu stone series or the Platinum upgrades, consider the Urushi. The Urushi avoids some of the bass and treble colorations for which the lower level Koetsu's are noted but retains that wonderfu... 
Building high-end 'tables cheap at Home Despot II
Those great speakers of the 50s have never gone out of fashion for some and are now in a mini-Renaissance of sorts, as more and more folks tire of modern, constricted, and dead sounding "hi-fi" speakers that need 250W of transistor power to make t... 
Building high-end 'tables cheap at Home Despot II
Don't really know why I continue to use the clamp (as a record weight, really). Probably it has something to do with a deep-seated insecurity, perhaps some fear that if not weighted down, the LP will rise from the platter like a flying saucer. I a... 
Building high-end 'tables cheap at Home Despot II
I've been using my Sota Reflex clamp with my Giant direct-coupled Lenco. But honestly, I don't hear any difference with it vs without it, for better or for worse. I don't activate the clamp mechanism; I just let the clamp ride on the spindle. I th... 
Do enzymes only live for 8 hours
What's the problem? Enzymes degrade slowly over time; they don't go away suddenly after 8 hours. Different enzymes in solution will lose activity at different rates, and temperature and buffer content are other factors that will determine the rate... 
Do enzymes only live for 8 hours
Biologist here. All enzymes ARE proteins. It is folly to make generalizations about the lifespan of the activity of an enzyme, because they are all different. However, they can be grouped based on their specificity, half-life (time it takes to los...
