| Best resistors for use in phono stage? That's quite true, but I am convinced that much of what we listen to is dielectric absorption, or DA. This seems to be minimal in five components: bare wire, vacuum caps, air gap caps, nichrome wire resistors, and slightly behind these, Vishay VAR... | |
| Best resistors for use in phono stage? Three terminal regulators - how true. I burned the better part of a day last month on a circuit that wouldn't behave, only because a 7806 failed in a highly non-linear way. Name brand device, too. | |
| Best resistors for use in phono stage? My opinions are based on solid state in a vinyl / ESL system. The Vishay VAR series are rated at 300 V if IIRC, so they are suitable for any place in the amp (unless you are driving ESL's directly). IMO, VAR are better than any of the Caddock res... | |
| Best resistors for use in phono stage? Larryi is right. | |
| Turn down the Volume! ESL's played quietly. Occasionally at 'normal' volume. | |
| How best to eliminate LP warps @jazzguy43 , I would suggest that it is more a matter of correctly applying the laws of nature to a given situation that matters. Second Law is especially tricky to use - I’ve seen it used to explain why methane explodes in an enclosed volume, but... | |
| Best Stereo Upgrade Value Phono stage, speakers, turntable, in that order. | |
| Best resistors for use in phono stage? @itsjustme is absolutely right about how the loading resistor works. This is easy to see if you magnify the effect. Imagine a transistor across the signal line and ground, turning off and on. Then the signal would be grounded when the transistor w... | |
| I am taking a survey Lush and romantic, but not too much in the way of original themes or leitmotifs. Not Shore, not Devs, but a solid 3. Thanks for sharing. | |
| How best to eliminate LP warps @jazzguy43 I did the experiment. You were right, my intuition was wrong. My record remained unplayable even with the warp mostly suppressed. It seems that without constraining the boundary, the record remains damaged. | |
| What is your record cleaning regimen? 15 minutes US at 80 KHz and 75W per record, three rinses, air dry. Re-clean after 25 plays or so. I wouldn't blow on the record - saliva has both dissolved solids and oils. | |
| Need suggestions: High pitched female singers Cristina Deutekom singing in Mozart's 'Magic Flute'. Sings Queen of the Night with much enthusiasm - coloratura soprano at its best. Solti conducting. Joan Sutherland singing the songbird in Wagner's Ring, also by Solti. | |
| Do you consider cables to be a "component" of your system? Yes - but the least bang for buck. By a long way. Since I DIY with electrostatics, I can use nichrome wire for speaker cables instead of a tuning resistor - so effectively no speaker cables at all. For line level, Canare Starquad microphone cable... | |
| Dumbest cable question Connections can get dirty or corroded or oxidized over time. When you break a connection and then make it again, you get better contact. Which is why one can often hear an improvement after doing so; for example, by reversing the direction. | |
| Why do preamplifiers have so many capacitors? Or, if you want a more formal textbook, 'The Art of Electronics' by Horowitz and Hill is a bible of practical methods. A section in Chapter 1 talks about capacitors and their different characteristics. But also note that although materials are a... |
