| Eminent Technology ET-2 Tonearm Owners Dover."yet again you miss quote me"I think not. See your post 03-13-13. Where you go to great lengths to show, incorrectly, that when tracing eccentric records, my arm is 300% heavier than a standard ET2. The leaf spring is inactive at eccentric r... | |
| Eminent Technology ET-2 Tonearm Owners Dover.Up till recently you have been telling us all repeatedly that the counterweight decoupling spring is active at eccentric record frequencies and that at these frequencies my arm is up to 300% heavier than a standard ET2. We now all know that ... | |
| Eminent Technology ET-2 Tonearm Owners Frogman.Look to the other end of the arm and compare the counterweight attachment. If you are using a low compliance cart on an ET2, this is the main cause of diminished bass extension. Calculate your FR using the ET2 manual formula. Around 7Hz or... | |
| Turnable database with TimeLine Don.re your post to Lew. "Nobody has used the timeline.... and detected any audible sonic changes."Firstly. The time line shows average speed per revolution. A TT that passes the timeline test has a "consistent average" correct speed, no more than... | |
| Turnable database with TimeLine Dover,Less than 0.3 seconds servo response came from observing current draw modulation in the kHz range, in sync with the music being played. The test was done with the system muted and live to check if it was some sort of acoustical feedback phen... | |
| Turnable database with TimeLine Actusreus.Re my last post and tracking progressively towards the center grooves.For clarity, I should have said it progressively becomes less slow as the torque demand decreases.Lew The servos we use at my work can have response times in the micro... | |
| Turnable database with TimeLine Actusreus. Assuming 1)the stylus drag is constant throughout the LP 2) the TT slows due to stylus drag,3) speed control is open loop ( maybe) Then it will naturally increase in speed as it tracks towards the centre grooves.This is a torque moment ... | |
| Turnable database with TimeLine While I agree that it would be best for every test to use the same LP, this is likely an unrealistic requirement since it presupposes that every tester has this disc. Futher " The sum total of the error at the end of the test would be truely compa... | |
| Turnable database with TimeLine DonI don't think that any of us are claiming perfection. Well maybe one of us is. But we are, most of us, on an impossible quest for same. Religious? Maybe a substitute, but it is a whole lot of fun. Given the manyfold problems of vinyl playback, ... | |
| Turnable database with TimeLine Lewm8 feet to the wall, that is a tough test.Don_c55I understand your skepticism, but would argue that these micro speed changes are indeed audible.Sure we have tape machine speed instability along with eccentricity problems. That said, speed chan... | |
| Turnable database with TimeLine HalcroOk.., what is the music this time?NiceLewmI missed your report on the MK3 with the Timeline. Are you able to repeat them here?Thanks | |
| Turnable database with TimeLine HalcroAgree it would be nice to have consistency in the test methods.HF Dover Phase lag is a result of drag, not a cause of it. | |
| Turnable database with TimeLine HalcroFor consistency, as you have done, it may be advisable for people posting videos to show say 1 minute of stylus raised followed by a time with it lowered playing some robust music. Something like the lovely piece you played.While having the ... | |
| Turnable database with TimeLine Regarding the eddy current brake as used in the Beat TTGo to teresaudio.com and follow the link...micro precise speed technology.The Certus motor.As I said earlier, this is an elegant design. | |
| Turnable database with TimeLine HF DoverYou appear to have invented a whole new type of motor. One where the rotor follows the rotating field with zero phase lag. Please explain to us all how such a motor produces any torque.Also one which "Instantly" draws more current and supp... |
