| Sibilance issues with vinyl rig Just went through this issue in another thread with VPI JMW-9. You need to try weighting the headshell with a 5gm nickel applied with double-sided padded tape. That will increase the inertial mass of the arm to better control the cartridge. It sho... | |
| Sonist At T.H.E Show in Vegas this year Sonist sounded great with DeHavilland-- a big step up from Randy's prior exhibit with Glow. | |
| How to measure tonearm effective mass Mark, My tonearm has the front and rear counterweights riding on separate threaded rods going into the pivot and independent of the arm tube. Thus adjustment of counterweights does not affect the secondary resonance characteristic associated with ... | |
| How to measure tonearm effective mass Lew, All I can contribute on this subject is the result of modifying a linear arm to allow micro adjustments to effective vertical mass across a wide range of adjustment. This set-up separates observations related to changing effective mass from o... | |
| Magnepan 3.7 Agree with Weseixes that the smaller Maggies are in the sweet spot of the product line. At CES 1.7s sounded remarkably good with Rogue electronics. 3.7s with Bryston at T.H.E. Show were relatively congested and dull. I lean toward blaming the 3.7s... | |
| Kleos Sibilance Agree with above comments that you should break it in longer before judgment. It is also worth checking to see if a change in effective mass affects the sibilance. Try weighting the headshell with a 5gm nickel & rebalancing the counterweight. | |
| The Placement of Tonearm Counterweights "Decoupled" was perhaps misleading. The idea is to vary vertical effective mass using a system other than the traditional relationship between arm wand length & mass. Freed from considerations of mass, the wand can then be optimized solely for... | |
| The Placement of Tonearm Counterweights If an arrangement of dual counterweights placed front and back of the pivot point is entirely decoupled from the arm wand and offers a wide enough range of adjustment for an exact match of tonearm inertial mass to cartridge compliance, then it is ... | |
| The Placement of Tonearm Counterweights I try for the simpliest approach that addresses the main problems of physics. The first principles are:The ideal arm is such that on a flat LP, stylus deflection associated with normal tracking produces no vertical movement of the cartridge. (Hori... | |
| The Placement of Tonearm Counterweights Hi Bob,The Moerch is certainly beautiful, and like other pivots does variable effective mass and other nice things with interchangeable armtubes. However I'm done with long resonant arm tubes and the inevitable junctions in wiring attendant to det... | |
| The Placement of Tonearm Counterweights This makes good sense. However varying mass v. distance on just one side of a conventional pivot arm has the limitation of a relatively small range of adjustment. To devise a "universal" arm with continuously variable effective vertical mass, I've... | |
| Best Jazz of 2010 Charles Lloyd Quartet "Mirror" is up there. Also a few interesting off-track efforts like David S. Ware "Onecept" and Nels Cline "Dirty Baby." | |
| I am at the end of my rope, please help Ralph, I would add to your list the experimental reversal of cartridge phase on one channel-- no matter what the ohmmeter says. Incorrect relative phase will definitely shift the image to one side.Also, has each tonearm wire been checked with an o... | |
| I am at the end of my rope, please help To be certain about correct relative phase, forget the ohmmeter and just try switching the red and green cartridge clips. | |
