| How to accomodate a balanced only phono stage ? (I was just about to click "submit" on the following, when I saw Dave's (Dgarretson's) post above. Thanks Dave).I should have added at the end of my previous post that there is a second reason why it is preferable to use a properly designed adapte... | |
| How to accomodate a balanced only phono stage ? The main purpose of the pin 1 ground connection on balanced interfaces between powered components is to keep their respective circuit and chassis grounds reasonably common. Where one or both of the two components has a 2-prong power plug, or is us... | |
| Pass Labs 150.5 suitable? Good point, Auxetophone -- thanks. I suspect that what you are saying is correct, now that I think of it (except that I think you meant to say "peak" when you wrote "peak-to-peak" or "p-p").So my reference to 2592 watts as being the limitation tha... | |
| The difference between impedance and resistance BUT you cant have C and L at the same timeActually, that's not correct. A real-world (physical) capacitor will have some small amount of stray inductance, and a real world inductor will have some small amount of stray capacitance. Both will also h... | |
| Pass Labs 150.5 suitable? Assuming that the speakers are truly a benign load as you indicated (meaning that their impedance does not dip down to very low values at any frequencies, and that they are not highly capacitive at any frequencies, such as electrostatic speakers w... | |
| What is the effect of age on audio components? In addition to Mlsstl's excellent response, you may find the following thread to be of interest. The bottom line: it's very unpredictable.http://forum.audiogon.com/cgi-bin/fr.pl?htech&1267845685Regards,-- Al | |

| The difference between impedance and resistance Hi Bob,In the case of a capacitor, the voltage between the two plates or conductors is proportional to the charge that has accumulated on them, the charges being equal but of opposite polarity on the two plates. Charge accumulates as a result of c... | |
| Unecpected and not understood tweek - help? If the front end source is a CDP, and basically the tape out jacks of the amp are connected in parallel with the CDP output, would that be causing the difference in sound Rpg is hearing? The output of the CDP is being affected. Hi Jim,Yes, that's ... | |
| Unecpected and not understood tweek - help? OK, well then I would suspect that the output impedance of the tape outs is much less than 47K, and also that the tape outs are not driven by separate buffer stages that would isolate the main signal path from what is connected to those jacks.So p... | |
| Unecpected and not understood tweek - help? If I understand correctly, you are saying that the sound when listening via speakers is affected by the connection of the V-CAN to the Krell's tape outputs. Does that occur with the V-CAN turned on, or turned off, or both? I would not assume that ... | |
| The difference between impedance and resistance Hi Bob,Re the use of radians vs. degrees, see the section on this page headed "Advantages of measuring in radians," which begins by stating:In calculus and most other branches of mathematics beyond practical geometry, angles are universally measur... | |
| The difference between impedance and resistance Hi Bob,The 2pi factor converts the units of frequency from cycles per second (Hertz) to radians per second, one radian equaling 360 degrees/2pi = approximately 57.3 degrees.The need for using radians per second is inherent in the calculus (differe... | |
| Why is high capacitance good? Hi Pani,What would be best, of course, is an analysis reflecting the particular component impedances, cable lengths, and cable parameters that are being considered. But that is probably impractical to cover here in a generally applicable way. And ... | |
| The difference between impedance and resistance Hi Magfan,Yes, your statements are correct, and the posts you have made emphasizing the importance of phase angle and how resistive vs. reactive a speaker load is are good.A pure inductance or capacitance (with a phase angle of plus or minus 90 de... |
