| MOSFET "no need to go onto MHz ranges I believe" In general, to keep things stable output stage should be as fast as possible (little phase shift)and input stage as slow as possible (large phase margin). Power output transistors of modern amplifiers have... | |
| Zero Feedback: Atmasphere vs. BAT Scottlanterman - I read very positive review of Atmasphere (MA-1) but what makes them hot is amount of current that tube heaters consume. Each tube is about 6.3V 2.5A and there is 28 of them total. That equals to 441W dissipated power just for the... | |
| MOSFET There is no perfect device. Mosfets output stages are:- more robust than transistors- have higher bandwidth - are more tolerant of difficult loads but are:- less efficient since have lower voltage swing from the same supply voltage - are more nonl... | |
| S/C: DH Labs Q10 vs Nordost Super Flatline Acdvd - I have shotgun version and never tried regular. Difference should be very small and is speaker dependent. My brother has biwired version of Q-10. Nice cable but not the same class as Satori. Satori is very thick. It uses 6N zero crystal co... | |

| Who has dumped the power conditioner? Tbg - People who post about their experiences with gear help me a lot to make decisions and learn, while people who say that everything is relative and I should listen to music instead don't help at all. | |
| Amp damping factor? Pauly - I agree. Specifications are very flexible and often misleading. Amplifier (and any other) design is a series of compromises and when you see an amp with exceptionally high DF and extremely low THD something else has to give - the sound. Jo... | |
| Amp damping factor? "An amp doesn't have a damping factor"Pauly - You'll often find DF in amps' specifications. "Having" DF simply means amp has that many times lower output impedance (at given frequency) than assumed 8 ohm speaker. DF is a measure of output impedanc... | |
| Amp damping factor? Deep loop feedback is equivalent to high gain before feedback. With such high gain (in order of thousands)any delay in the signal path (limited bandwidth) results in improper (late) summing of the input and the feedback signal causing TIM - tenden... | |
| Amp damping factor? Atmasphere - also speaker design can make for better quality of bass. As far as I know typical, used in 90% of cases, overhung motor speakers have a lot of distortions at lower frequencies. More expensive underhung speakers,used by some manufactur... | |
| Amp damping factor? "Digital amps seem to be the exception which normally have a damping factor of up to 1000".My Icepower amp has DF=4000 at low frequencies. It is inherent in class D amps since speaker is always shorted by Mosfets to power and GND (to very low sour... | |
| Amp damping factor? Inductor in-series with the woofer has resistance approx. 0.08 ohm limiting DF to 100. | |
| Who has dumped the power conditioner? Some people should get INEGRITY ! | |
| Who has dumped the power conditioner? Let me get this straight - (I can laugh during it if it makes you feel better):Prosound who is rep for Silver Circle Audio makes sales pitch (I don't have any other name for that):"This power conditioner simply out-performs every other conditioner... | |
| Who has dumped the power conditioner? "However, in a sense we are all reps..." - Are you trying to muddy the water? Repping product is a contract activity not the state of mind.One thread though, hmm?...still a little suspicious - not really. For me this forum is an opportunity to lea... |
