Raven One Motor Noise Problem
Without ever having seen a Raven One, but just from my past experience with turntable motors, I do not think that your experiment proves that your motor is OK. It would seem to me that the motor should not need a Vibrapod to make it quiet, and I d... 
Cardas Frequency Sweep and Burn-In Record ?
Tracks 2a, b, and c (I think) are great for reviving a cartridge that may be broken in but has not been used for several weeks. 
2 turntables and one phono stage - Can I???
FWIW, with respect to Almarg's comment, you should probably use a DPDT switch, so as to switch both sides of the two cartridges simultaneously. There should be no problem with that. The shield would be separated from the so-called "hot" and "groun... 
2 turntables and one phono stage - Can I???
As Sidssp inferred, you COULD use a splitter, if you also used a switch, so that the phono circuit was only "seeing" one of the two cartridges at any one time, or to put the same concept in another way, so that the cartridge you are listening to w... 
Tripods as turntable or component base?
Hifigeezer, With all due respect, Stereo Review was a rag. But Mike Fremer did use accelerometer(s) to evaluate the Finite Elemente and the Monaco Grand Prix stands and reported his results in Stereophile. His tests generated quite a furor among d... 
Tables That Feature Bearing Friction
Berlinta, T_bone, Raul, Dave, et al: Do you all except Dertonarm's contention that belt drive is the inherently superior way to motivate a platter, compared to all forms of idler- or direct-drive and notwithstanding theoretical air propulsion? It ... 
Tables That Feature Bearing Friction
Dertonarm, You are entitled to your opinion, but please acknowledge that you DO have an opinion - that the ultimate turntable must have a humongous platter driven by a string or thread. That is an agenda in itself. You have closed your mind to oth... 
Tables That Feature Bearing Friction
Dertonarm, For your consideration, an idler-drive in which the motor force is applied to the underside of the platter, in the vertical plane. Thus no horizontal force needs to be cancelled. No string needs to be chosen or "adjusted". In short, I o... 
Tables That Feature Bearing Friction
Dertonarm, You have written that there should be no force on the bearing in the horizontal plane, and elsewhere you have written that use of more than a single motor is a no-no. (I agree in both cases.) But how would you achieve the former goal in... 
Tables That Feature Bearing Friction
Syntax, In that third photo, is the platter on the right driving the platter on the left, as it appears? This is in keeping with some of Mark Kelly's teachings on "belt creep" and how to prevent it. Anyone interested in this topic should search on... 
Tripods as turntable or component base?
Reason for a tripod or 3 feet under a piece of gear: (1) Easiest to level; (2) The weight of the supported object will be evenly distributed among the 3 pods, once the object is level and if the tripod is properly implemented, (3) Fewest paths for... 
Tables That Feature Bearing Friction
The string "belt" on the mammoth turntable in the photo is WAY too long for optimum control of platter rotation, even if the string has no stretch at all, but I guess the inertia of the humongous platter mass compensates for this problem to a degr... 
Tables That Feature Bearing Friction
What I wrote was that any effect of stylus drag on speed will in part be a function of the distance of the stylus from the spindle (not "distance from the stylus"). I was referring to the mechanical advantage gained by applying a force some distan... 
Tables That Feature Bearing Friction
Dertonearm, You wrote, "Stylus drag is a very small sliding force in constant motion and is - coupled with any serious platter (of course not if the LP lays just on the platter and is not firmly clamped down) - really neglectable. Its a force smal... 
Turntable in 20 K$ price range - Design & Music
Davidri, Given your criteria, and since you, like most here, appear to believe in a linear relationship between retail price and sound quality, why not just pick between your two choices based on appearance? They are both excellent, and no one is ...
