| Balanced versus single ended Anyways, my question is: has anyone ever thought that single ended sounded better?given the 2 options. Im only referring to a truly balanced connection. I ask, because a manufacturer who makes tube amps, recommends single over balanced connectio... | |
| Voltage mode vs current mode phono stages @lewm Since the cartridge functions as the input resistor to the opamp, the impedance of the cartridge affects the gain of the circuit (as you probably know, the gain of an opamp will be the ratio between the feedback resistor and the input resist... | |
| Voltage mode vs current mode phono stages Isn't the difference between a 'warm' and 'lean' sounding system a shift in frequency responses? @ledoux1238 IME on a system level that is often caused by distortion. The ear assigns a tonality to all forms of distortion. Lower orders (2nd- 4... | |
| Pigskin or jico leather mat Ralph, the two or three times I have disagreed with you, you have been so freaking nice! I vow to not disagree with you any more. If you were to declare the Earth flat I would let it go. Seriously. If I disagree with you again I will just ask you... | |
| Can anyone identify this inductor? Iron inductors seem like a no-no. In fact, I got huge coherency improvements by taking anti-static and EMI measures on it with some usual hi-fi tweak products. I do not know if they even tried to orient it correctly. Sounds like you identified ... | |
| Pigskin or jico leather mat Just not true. This again is where intuitive/rational/objective/measurement based talk diverges from something called "listening". A platter pad with the same durometer as vinyl (is there such a thing as "the vinyl"?) may sound best with one turn... | |
| Voltage mode vs current mode phono stages whereas voltage mode is an endless pursuit of SUT’s and loading. I have admittedly rather entry level stuff, so not the final word. @ledoux1238 If you have the right voltage mode phono section, its also plug and play- no SUT and no worries abo... | |
| Cartridge Loading.....Part II The two statements you quoted from me seem to align well with each other and I was unaware that there was a different versions of ohms law for static vs dynamic loads At any rate, Moncreif threw off his numbers by using a 5 Ohm load I agree it ... | |
| Two vs four subwoofers for music playback My main speakers already go to 20Hz. But due to a standing wave in the room, there was no bass in the listening position! I added a pair of Swarm subs and it took no fiddling (once I placed the two subs I've not had to move them at all nor mess wi... | |
| Pigskin or jico leather mat I have pondered just making one The job of the mat is to control vinyl resonance while the cartridge is tracking the groove, thus preventing the vinyl from talking back to the cartridge. This results in measurably and audibly superior performa... | |
| Cartridge Loading.....Part II I didn’t mention a dead short and was only referring to the two terminal impedance the coil of a cartridge sees. Any reference to ground be it real or virtual does not factor into the load seen by the coils. Surely there has to be an actual input... | |
| Balanced v high-pass You need a set of Jensen ISOMAX boxes set up for XLR in and RCA out. They work great for exactly this sort of thing. https://www.jensen-transformers.com/product/sub-1rr/ Don't be fooled by the one in the photo- they can be ordered with the connec... | |
| Cartridge Loading.....Part II When you consider the proliferation of "current mode" phono inputs in vogue the 5Ω value isn't so strange. Transimpedance phono sections have the cartridge driving the 'virtual ground' of an opamp circuit. That's quite a bit different from driv... | |
| What's a good amount of time to have my preamp unplugged before I swap out tubes? It should be mentioned that this thread's advice is for changing tubes in PREAMPS ONLY, YOU MUST WAIT A FAR LONGER TIME WHEN CHANGING TUBES IN AMPLIFIERS OR RISK ELECTROCUTION. This statement is incorrect, unless the amp has to be opened up a... | |
| Cartridge Loading.....Part II I would say no since the two loadings PM shows for his IMD are 5Ω and 100Ω both of which will surely damp any possible LC resonance which would then eliminate the whole RFI aspect. @intactaudio FWIW 5 Ohms as a load is so low that most cartri... |
