| Cartridge Loading- Low output M/C Bill (Wrm57), thank you kindly :-)Best regards,-- Al | |
| Cartridge Loading- Low output M/C Great info, Wyn; thanks! And thanks also to Catcher10 for his inputs. So, perhaps the answer to the loading question is, no matter how unlikely it seems- it depends on the architecture of your phono amplifier! This is exactly what Ralph (Atmaspher... | |
| Tekton Double Impacts @david_ten @343mpsThe visible text of the link in 343's post will work, but what is hidden "underneath" the visible text, which is what the browser is directed to when the link is clicked, has two extraneous characters at the end, namely ">Aft... | |
| Cartridge Loading- Low output M/C Hi Wyn,Yes, that is of interest. And I agree with your math, of course, while having two comments: First, I’m not sure that "back EMF" would be the best terminology to apply to what you are calculating, or the best way of considering it (see the n... | |
| Ugraditus is calling....again. Phono stage? Uberwaltz, the Chinook has particularly low output impedance (50 ohms nominal according to its manual; 91 ohms and a recommended minimum load of 2.5K according to its website description), so it won’t have any problem driving the 2170. Or most oth... | |
| Cartridge Loading- Low output M/C Thanks for providing the comprehensive simulations, Wyn.Regarding: Now 1000 pF. 0mdB at 20kHz, -32dB at 10MHz, 0.5dB peak at 1MHz.Now 10nF. 10mdB at 20kHz, -52dB at 10MHz, 3dB peak at 400kHz.Now 22nF. 20mdB at 20kHz, -59dB at 10MHz, 2.2dB peak at ... | |
| RIP Dave Wilson Very, very sad news indeed. A class act in every way, as well as one whose many accomplishments have provided countless audiophiles with enjoyment. I refer not only to the products of his speaker company, but also of his record company, and even h... | |
| Cartridge Loading- Low output M/C By the way, I still have no idea what you mean by energy of the cartridge itself etc. I didn’t say "energy of the cartridge itself." I said energy "generated by the cartridge itself," and I was referring to energy "generated by the cartridge itsel... | |
| Cartridge Loading- Low output M/C Thank you for joining the thread, Jonathan, and for providing the link. The text to the right of the last figure in the post Jonathan linked to is particularly relevant. Some excerpts [words in brackets are mine]:The resonant peaks have too high o... | |
| Replacing my Krell FPB 600 amp with a tube amp Thanks for the nice words, Dentdog. I found that information about the CAT JL2 in the measurements section of this review of the Signature Mk2 version of the amp, in SoundStage. The data provided near the top of the measurements page states "outpu... | |
| Replacing my Krell FPB 600 amp with a tube amp The impedance curve for the Matrix 800 that is shown in Figure 1 of Stereophile’s measurements indicates an impedance in the vicinity of 4 ohms in much of the bass region, as I mentioned previously, and more than 10 ohms at almost all frequencies ... | |
| Replacing my Krell FPB 600 amp with a tube amp A point to keep in mind regarding passively biamping the FPB600 with a tube amp, in addition to the gain matching concern that was mentioned, and in addition to the possible effects on coherence of driving the speaker with two very different amps,... | |
| Cartridge Loading- Low output M/C Are you perhaps stating that the increased current generated by the lower resistive load increases distortion? No, I was not saying that or implying that. And for that matter I have no particular knowledge of how the distortion performance of phon... | |
| Cartridge Loading- Low output M/C Hi Wyn,Thanks for providing the excellent and thought-provoking analysis. I see no flaws in it as far as it goes. And in fact the manual for the OP’s phono stage states that the higher capacitance setting (570 pf) can sometimes be beneficial with ... | |
| How much do I need to spend to get a preamp that sounds better than no preamp? Honashagen 5-26-2018 As I sit here listening with no preamp, it seems like common sense would tell you that if a preamp alters the sound from the source in any way it's really a processor of some type. Right? ... Unless, that is, the presence o... |
