| 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. | |
| surface noise and cartridge/ phono pre questions Panu21, it *can* be, but can also be a setup problem with the arm and cartridge. If the cartridge is not loaded properly, and is not set up correctly, it is conceivable that the additional RF energy that shows up at the end of the LP could bother ... | |
| Efficient speakers with high powered ss amp? Rischa, go look at the link I posted earlier. It relates directly to your question. | |
| Lifespan of a quality solid state amplifier? Most electrolytic caps used in power supplies will show some signs of failure before they start to leak. Most such capacitors have some sort of plug on the terminal end that will show signs of bulging prior to outright failure of the part.Its a ju... | |
| surface noise and cartridge/ phono pre questions Jcarr, I think you may find this article by Nelson Pass to be interesting:https://passlabs.com/articles/audio-distortion-and-feedbackIt seems to re-enforce some of your comments above. Norman Crowhurst wrote about some of this as well, although I'... | |
| Efficient speakers with high powered ss amp? You might want to look at this link:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpThe issue of the intention of the designer will play a huge role in this matter. In fact, if the amplifier technology does not match what the... |
