| highly sensitive loudspeakers for single ended poe To get the best results out of an SET, unless its fairly high powered, the speaker should really not be less than about 97 db. Otherwise the amp will be making a lot of distortion, meaning that it will not sound as transparent and will also take o... | |
| 6sn7 and 12sn7 octal preamp for under $5k The Atma-Sphere MP-1 has an all-octal line section but you won't find that in your price range used. The MP-3 uses a combination in the line stage and used they will be in the right range. | |
| Stylus Drag In any motor, AC or DC, if the load increases the current in the motor will increase too. This provides a feedback mechanism that functions well even on open loop systems. For an AC motor that runs off the line, if the motor has any torque at all ... | |
| What makes music so congested? Yes was one of my favorite groups back in the 70s. Close to the Edge is considered one of their classics, but the organ on side one always breaks up on any American copy. There are two editions that don't - the Mobile Fidelity re-issue and the ori... | |
| Preamp possibles for system... A true differential balanced unit will have to double the number of parts in some stages.This is not correct. It is true of *balanced* if not differential, but if *balanced differential* the parts count is less than double. | |
| Ground loop b/w amp and phono stage The most common problem when this shows up is a but in the arm wiring, FWIW. | |
| Active FETs vs. Step-up phono stage designs Hadn't really thought about that! We make two... it might be interesting to take a poll. | |
| Is there a list of cartridge capacitance? I'd be interested to see what you think! | |
| What makes music so congested? Philjolet, did you hear the British or American press? I never found the US press to my liking but the UK is great. | |
| Stylus Drag The fact that a platter slows when the stylus is in the groove is not the same as what as referred to as stylus drag.That is how I define stylus drag. What else would it be?? | |
| Active FETs vs. Step-up phono stage designs Dan_ed got that right...Its been my experience that you don't want semiconductors at the input of a phono stage- they just don't have the same low level detail as an all-tube phono section. I don't like transformers for the same reason- they limit... | |
| Is there a list of cartridge capacitance? Input the resistance and inductance for your cart, and input capacitance values to see what the resonant frequency is. I think anything above 20 KHz is fine, so capacitance values up to that resonant frequency should be OK. Yikes! When you are dea... | |
| Analytical or Musical Which way to go? David12, the Wilsons are voiced by listening too. If you have them on the right gear they are quite musical, also very revealing. But put them on the wrong gear and they can sound the way you describe.In speakers its really important to see what t... | |
| What makes music so congested? See if you find a British original LP of that and see if you still say the same thing (Atlantic 'Plum' label). The mix is OK FWIW, though its not going to be as spacious as many jazz LPs, its pretty standard fare for the period. Its not likely IMO... | |
| Stylus Drag You don't hear the change in pitch as such. You hear it as a shaky soundstage. Speed variation causes the tonearm to decrease and increase skating forces. This makes the soundstage less solid. This is why speed stability is so important. |
