| damping factor Good answers above. There is an additional factor that often needs to be considered, though. Damping factor and amplifier output impedance are inversely related. Damping factor, as usually defined based on an assumed 8 ohm speaker load, equals out... | |
| getting file onto usb flash drive I took a look at the manual.Unfortunately it does not say that Apple Lossless is supported. AAC format is listed (along with some others), which as I understand it uses the same MP4 file "container" and the same .m4a file extension, but is a diffe... | |
| Does the Direction of Twisted Cable Matter? Keep in mind that we are dealing with AC waveforms, and so the directions of conventionally-defined current flow and magnetic flux lines are continously reversing.It is my understanding that Current & Magnetic field flow through wire in a cloc... | |
| What is my next step to a better sound ? One thing that hasn't yet been mentioned is that if your connection between the Blu-Ray player and the RDAC is via digital coax, the LENGTH of the cable can be a significant factor. It should either be very short, less than say 12 inches, or it sh... | |
| Coincident Dragon Amplifier Thanks very much for the nice comments, guys.Waltersalas, you're most probably already aware of the need to make certain that any 300B used in the Renaissance amps conforms to the original Western Electric specifications (which many 300B's that ar... | |
| difference between an active and a passive preamp? 04-12-11: AlmargI can't envision a reason why the length of the cable between source and preamp would be any more critical than with an active preamp.05-18-11: AtmasphereWith passive controls, the cable length is quite critical as is the construct... | |
| Is equal gain OK for bi-amping? If the amps have 2 very different input impedances, say 20K and 60K and they have equal gain, won't the output volume be different also because of the impedance being un-equal?No. If the two preamp outputs are not separately buffered, the inputs o... | |
| Coincident Dragon Amplifier My amplifier upgrade recently occurred, and so I thought I would provide an update to this thread:While the thread was active I received a helpful, credible, and experience-based email about the original (and then current) version of the Dragon fr... | |
| Newbie question: Amplifiers, Volume, Clipping? Loomis, thanks very much! I always find your posts to be informative and enjoyable, as well.Best regards,-- Al | |
| Is equal gain OK for bi-amping? Minorl, your posts are always extremely knowledgeable and helpful, but in this case I'm not sure that you are correct regarding the need for sensitivities to match.As I'm sure you realize, sensitivity is the input voltage that is required to drive... | |
| Newbie question: Amplifiers, Volume, Clipping? Hi Bruce,My statement about the output waveform abruptly transitioning to an essentially constant level was not worded as completely as it should have been. The "constant level" will persist only until a tiny fraction of a second later, when the i... | |
| Newbie question: Amplifiers, Volume, Clipping? No eye-rolling here, Stan, just a good chuckle at your comment :-)The reason that speakers are commonly damaged by clipping of underpowered amplifiers is essentially as follows: Clipping occurs when the amp is asked to deliver a larger voltage swi... | |
| Dollar to Satisfaction Ratio not met. Hi James,I couldn't find an input impedance spec for the line-level inputs of the Hsu sub. But I would feel pretty certain that the Burson buffer would have no problems driving the combined input impedances of the DNA-500 and either the sub or the... | |
| How do you judge your system's neutrality? Once again I am in complete agreement with Bryon, despite the fact that his latest post perhaps negates my earlier claim that nothing is perfect :-)Regards,-- Al | |
| Dollar to Satisfaction Ratio not met. An additional thought: How are you hooking up the sub(s)? I don't know whether or not the two XLR output connectors for each channel that are apparently provided on the BAT are individually buffered, but I would guess that they are not. If that is... |
