| Matching up speakers and amps You should go ahead and do that then. The Spendors have usually been tube-friendly. | |
| a solid state amp that is recessed in the treble The problem has three elements. If you have ever wondered why a tube amp and a transistor amp can have the same bandwidth but the transistor amp sounds bright here's why:Our ears are tuned to listen for the odd ordered harmonics in order to determ... | |
| VDH Colibri XPP. Best Load impedance? The inductance of the cartridge is what speaks to the loading value. In this case the 500 ohm resistance value is also in question, but even if it were so, the inductance is what interacts with the phono cable capacitance to set up the tuned RF ci... | |
| highly sensitive loudspeakers for single ended poe David12, the difference between 10 watts and 20 watts is 3 db. That's not a lot to the human ear- something else is going on.SETs make very low distortion at low power levels. Once they get over about 25% of full power, then a substantial amount o... | |
| VDH Colibri XPP. Best Load impedance? Josef, as stated in several other threads, unless your preamp is sensitive to Radio Frequency Interference (RFI) then the loading will not be critical. If you find that it is, then your preamp is having a problem (and if it were me, I would consid... | |
| 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?? |
