Believe it or not there are people who might actually think a Shakti stone might acutally do something for their stereo, just like there are people who think that damping factor is an important specification for amplifiers. Damping factor *is* important albeit the the typical numbers quoted for SS amps are so high as to be beyond worrying about from the perspective of choosing one over another based on that parameter. For small signal conditions, yes. For large signal conditions, yes as well. But have you experienced the condition where one amplifier which is rated nearly flat to 20 Hz provides noticeably inferior bass to another with similar specs? Obviously you haven't reliably experienced *anything* relevant to your claims, Robert. A lot of your strange perceptions seem to be related to the observable fact that you hate doing listening tests where relevant variables are maintained as stable as is reasonbly possible. For evidence of your hatred for controlling relevant variables during amp tests, anybody can see all your ranting and raving here ABX. ABX is just about basic experimental controls. In addition Robert, I seriously doubt you are controlling other relevant parameters, momentarily putting bias controls aside. Things like level matching and checking frequency response with real-world loads. If you were actually monitoring these parameters, your posts would loose their profound aroma of ignorance of real-world facts. The reason is that damping factor is not reported for large signals. Don't know about that, but every time I've measured amp source impedance at its output terminals with large signals, nothing changes appreciably from the small signal numbers. But Robert you're playing expert here. Why haven't you delved into any of this stuff yourself? You say you're so much smarter and wiser than I am - why do I have so much practical experience with this relatively speaking, and you demonstrate none? Robert, is it that you are locked up some place where you can't get your hands on sharp objects like meter probes? Meter probes and all the stuff that goes with them are readily availble for reasonable prices. Why aren't you more familiar with their use in an audio context? IMHO, this is one of the major shortcomings in the quantitative analysis of amplifier performance. Only in your mind, Robert. For an amp's source impedance to its load to change appreciably, it would have to be appreciably nonlinear. Until you clip 'em, SS amps are nothing if not linear at low frequencies where you started ranting about in this post. |
