| Cartridge loading Raul, Likewise, I wrote the above post before I saw your response to Dave. No problemo. | |
| Cartridge loading For the record, I did mention the relationship between the input impedance of the Intactaudio device and the output Z of my MC2000 (2 ohms into 20 ohms), by way of speculating on how it is working with that particular cartridge. Nearly any very LO... | |
| Cartridge loading Raul, Intactaudio made measurements of frequency response and IM distortion, I think. You are here reporting your subjective impression, which is fine, but there’s a big difference. | |
| Phono Preamp Tube Rush three-easy, I would expect that different persons would get different results, if each person were to replace the stock tubes with the aftermarket brand you selected, because to a great extent it depends upon the pre-existing condition of the tube... | |
| What is the appeal of the Denon 103 cartridges? Tubehead, The formula in the form you quoted is the same as mine, except you start with the end of my calculation. It's just algebra. But 99% of the time, one is going to use the formula starting with a known turns ratio in order to determine th... | |
| speed controller for Lenco or Garrard karma, Here is how I would think of the two alternative products you are considering: Even though you don't need the motor, with the Eclipse you get the tachometer that feeds back to the power supply and maintains speed at a near perfect range ar... | |
| Which cantilever to choose for re-tip I can't swear to this, but I do believe the Mk3 was at most only a few hundred bucks more than the Mk2 (not double the price of a Mk2), last spring when I was in Tokyo. It may even have been the same price. I eventually bought a Mk2 Mono. | |
| What is the appeal of the Denon 103 cartridges? Tubehead, you may have misspoke by accident. The formula relates the reflected impedance as inversely proportionate to the square of the turns ratio. (For a 47K resistor load, a 1:10 SUT will reflect 470 ohms to the cartridge, as you correctly sta... | |
| Cartridge loading I was merely pointing out that there is some merit in this idea of a "current-driven" phono stage for certain very LOMC cartridges, even though the use of the term may be semantical or to put it another way, an exaggeration. On a practical level,... | |
| speed controller for Lenco or Garrard First, SOTA, the company that makes turntables, hooked up with Bill Carlin, the person who owned and designed the Phoenix Engineering gear, and SOTA now markets the Phoenix stuff under the "Eclipse" name. This includes an AC power supply like the... | |
| speed controller for Lenco or Garrard If the current SOTA Eclipse power supply and tachometer are like their Phoenix Engineering forerunners, you cannot go wrong by buying that ensemble and using it to drive your Lenco motor. (No need to buy the Eclipse motor along with the power supp... | |
| Cartridge loading bydlo and larry, I wouldn't argue with what you both say, but I would point out that the capacity of a LOMC to make signal current into a very low resistance load (meaning a load that is equal to or much lower than its internal impedance) does not... | |
| Which cantilever to choose for re-tip By the way, I am only quoting the advice of Jonathan Carr, who designs Lyra cartridges for a living. He also pointed out that there is a significant difference in mass between boron and sapphire, which would have led the original designer to choo... | |
| Turntable recommendations The alacrity with which certain persons state their personal preferences as absolute fact always surprises me. I won’t name names. Tasty, you keep asking about Vertere turntables. Could you be referring to “Verdier”? The Verdier Platine is a clas... | |
| Which cantilever to choose for re-tip The best philosophy is to stay with the original cantilever material because the cartridge was designed and built with that choice in mind. So your answer is “boron”. This has nothing to do with one being “better” than the other. |
