| Tube PHONO preamp interference - RFI, EMI, bad grounding? That photo showing a 33 ohm resistor partially encased in yellow shrink wrap looks like very amateurish work. Could be the ill advised work of a previous owner. Also, is that resistor connected at its other end? If not, it’s not doing a blessed th... | |
| What is the “World’s Best Cartridge”? Raul, in your own experience, what is the best sounding cartridge? Did you hear it in your own system or someone else’s? Thanks. | |
| What is the “World’s Best Cartridge”? The idea of Raul and Ralph kissing is to say the least, not attractive. | |
| Direct Drive Terry, I am well aware of the assumptions we make when we speak of turntable speed and its accuracy or lack of accuracy. But if you categorically prefer BD turntables, with or especially without a dedicated motor controller, it’s not because BD tu... | |
| Direct Drive Terry, amidst all the verbiage and math, are you saying you heard an SP10R and it was noisy even compared to older Technics DD turntables? Or what are you saying? By the way, JP Jones analysis took into account and measured speed changes over ver... | |
| Direct Drive I have to take issue with Bliss, who wrote, "There are some incredible direct drives, but their notoriety was largely due to motor noise and vibration." I don't mean to pick on Bliss, but his statement is often the mantra for those who don't care... | |
| What is the “World’s Best Cartridge”? Even the fruitless discussion of "what is the best cartridge" was more interesting than this banter about digital vs analog. None of the protagonists is ever going to be dissuaded from his or her point of view, so best to live and let live. Howev... | |

| Tubes and GAIN on Cary Rom-808 There are a few factual errors in Jason’s posts. Use of a cathode resistor does not necessarily limit the ways in which the tube is biased . Current is measured in amps, not “watts”, but if you multiply plate current by plate voltage (voltage from... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? If the transformer itself is humming, try tightening down on the screws that hold it to the chassis, and on the screws that hold the laminations together. Sometimes the case of the transformer can be a little bit loose and this can allow the lamin... | |
| What are some high impedance cartridges? Depends also on phono stage gain and linestage gain, if any, and etc. Many use the Denon or the Benz with 1:10 SUTs. I assume their downstream components make up for the lowish signal voltage. | |
| Transimpedance phono stage Also keep in mind that current driven phono stages really work best with LOMC cartridges that have very low internal impedance, for example, less than 10 ohms is ideal. This is not to say that those stages won’t work and sound good with LOMC cartr... | |
| FR64 to FR66 conversion Analogmagik Also check out Halcro’s plinth for his TT101, photos to be found in his long thread where we argued about outboard tonearm pods. Key word for reference is “Copernicus”. | |
| What is the “World’s Best Cartridge”? So if digital is now perfect and battery supplies are perfect, who needs the world’s best cartridge? (Sarcasm intended.) | |
| FR64 to FR66 conversion Analogmagik I can only fairly say that to my ears the stiffened OEM plinth plus the mass-loaded mounting board plus the FR B60 base for the FR64S sounds “bigger” and with superior bass response compared to the original configuration. I could send photos if yo... |
