| I made a pair of Voigt pipes and Shirasagi: I do what i can and am glad that this helped your understanding a bit. As i've mentioned before, if you really want to learn, you've got to do it yourself. I'd be glad to recommend some books if you're really interested. Personal experi... | |
| Negative feedback, voltage and output impedance Wasn't there a relatively recent review of a tube amp in Stereophile that had user adjustable negative feedback? If i can remember correctly, this not only affected the output impedance but also the bandwidth / linearity of the entire design. Was ... | |
| Current Trends in multi thousand dollar speakers Cdc: While i personally believe it takes "big power" to do bass correctly with most "audiophile approved" type speakers, this is only a very small percentage of the big picture. None the less, i put my money where my mouth is and have 1000+ wpc dr... | |
| condenser versus direct coupled? WOW is right!!! I guess you can learn something new every day. I'm obviously WAY out of touch with this aspect of "power delivery". Thanks for doing the legwork and correcting my screw-ups. Sean. | |
| Is it best to use a 5-channel amp for biamping?? I hate to say that anything is an absolute as there are almost always exceptions to every rule. With that in mind, it would be pretty safe to assume that you should be "okay" even with goofy internal wiring in the speaker so long as you were runni... | |
| Negative feedback, voltage and output impedance As a general rule, higher amounts of negative feedback will lower the output impedance. If you want a technical explanation of this, your best bet would probably be to head over to the Tube Asylum and ask there. Sean> | |
| Is it best to use a 5-channel amp for biamping?? If a speaker requires that all four binding posts be hooked up in order for all of the drivers to operate properly, one can passively bi-amp with out a problem. There is one hitch to this though...If the speakers are improperly wired internally AN... | |
| Classic Rock Listener - Help me build my system Dave: You really should find out what all the switches do. The potential sonic differences might be quite a bit when properly configured. Dudleston typically includes some type of switching for the "warmth" region, which may help lean out the uppe... | |
| I made a pair of Voigt pipes and Viggen: Pretty interesting stuff. For those that want to check it out and are lazy, here ya go : )http://tweakstore.com/index.htmlCdc: Did i "do good" on this one? I actually presented usable information with a technical explanation while praising... | |
| Classic Rock Listener - Help me build my system Bob aka Reb: I was referring to the newer series of Classe' amps. The 15 that you mention was closer in design to that of the original DR ( which stood for David Reich ) series. The DR's were probably the best sounding Classe' amps in my opinion. ... | |
| condenser versus direct coupled? "Actually, as I think you must know perfectly well, the rms voltage of a sinusoidal waveform (its heating power) is 7/10 that of its peak voltage, which is presumably what you are assuming for DC from a faulty amp."7/10th's is the same as a 30% re... | |
| Is it best to use a 5-channel amp for biamping?? Greg is right on the money. Increasing power potential is always a great thing, but if you can shorten the signal path between the amp and the speakers by removing passive components in the crossover, that will get you even better results. While t... | |
| CDP - running only one channel, can this damage? Not all components are built to the same standards of construction or use similar circuitry. As such, i was promoting a "low cost / common sense" approach that guarantees safe operating conditons for ANY type of device. When making suggestions / c... | |
| 120 or 240 AC current, Which one do you like best? 220 / 240 would be preferred if possible for multiple reasons. Just make sure that ALL of your gear is capable of running at those voltages. You may want to run an extra 110/120 line for future purchases or temporary use "just in case". Sean> | |
| CDP - running only one channel, can this damage? Signal is still being passed and amplified without the proper load terminations. The amplitude of signals is reduced due to the lack of current flow, but that doesn't mean that the devices aren't sustaining some type of wear and or damage. Try tak... |
