| Turntable speed accuracy Halcro, I'm not sure I agree with Peter on this one. Our model 208 has the motor quite close to the platter (opposite the tone arm; there are no hum problems even with Grados). However the 208 uses a motor that would easily qualify as a flywheel i... | |
| pass labs xa30 to valve amplifier. Slam and attack with clarity? Tube amps can do that in spades. A lot of that has to do with the relationship between the amp and the speaker:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpTube failure should not be a cause f... | |
| Retip Transfiguration Orpheus They,however, politely declined to do a retip/repair etc citing the non availability of parts on a small scale etcYes- *very* small parts...I was told that the Orpheus was (temporarily, at least) no longer available because the gentleman that does... | |
| Turntable speed accuracy The platter also does not keep rotating very far after the motors are switched off indicating perhaps a bearing designed for friction so that the motors have a load against which to pull?Halcro, I can't think of a reason for a bearing to provide d... | |
| Tube amp decision - Thoughts True, but what is the tradeoff? If there were none, I would imagine they would build high-efficienty speakers (unless they also sold high powered amps) :) No?The problem with high efficiency speakers is that the drivers cost about 10 times more th... | |
| Hum, buzz, snap, crackle and pop? Does the unit make snap crackle and pops when the needle is not on the record? If so tube replacement is good advice.If no, then you have a setup problem and tubes are not indicated. | |
| pass labs xa30 to valve amplifier. Pubul57, as best I can make out, Bobby is pretty conservative with that 89db rating on the Merlins. | |
| Is upgrading worth it? 70s music sounds fine on my system. I like to use bad recordings to test my gear- it should not editorialize if the recording is messed up. I have found that a lot of equipment *will* get upset when you play a bad recording, and make it worse, eve... | |
| Turntable speed accuracy But in general, a good direct-drive motor WiLL have more torque than a good belt-drive motor.As a generalization that is incorrect. A DD drive has to spin at 33 1/3 rpm. In a belt drive, there is a tremendus amplification of torque of the motor af... | |
| Lifespan of a quality solid state amplifier? I've seen corrosion at the terminals open up computer grade caps that were only 5 years old.It is true that heat will shorten the life of an electrolytic. But even if there is no heat, to continue to operate an electronic piece with 30-year old ca... | |
| Kate Bush My copy is fine. I played at CES/THE Show as a demo. | |
| Linear tracking arms and compliance... If LPs were perfectly concentric like they are supposed to be, I can imagine that having a high lateral tracking mass would have its advantages. But in real life, concentricity is something that we hope for and often come very close to getting, bu... | |
| TriPlanar Tips The coupling of the arm to the plinth is paramount in any turntable. IME you do not want anything to interfere with that. | |
| Linear tracking arms and compliance... The problem you have with a really short arm is two fold. First, warps can cause audible speed variation. Second, by the nature of the device, the pivot point of the arm bearings must be placed above the plane of the LP. This results in variable t... | |
| Tube amp decision - Thoughts Efficiency is really important in a speaker. It gives you a lot more flexibility with your choice of tube amplifier. |
