| First Watt: current vs voltage A current source amplifier has a very high output impedance- usually multiples of the speaker impedance.A voltage source amplifier has a low output impedance, usually a small fraction of the speaker impedance.Either one can sound good, but as far ... | |
| Dynamic speakers for OTL amps Audiokinesis showed a 2-way speaker at RMAF last year call the Stratoprism that may well suit the bill. It was moderately priced and very easy to drive- with that kind of power and the efficiency of the Stratoprism you would have no worries in a r... | |
| XLR to RCA Adapters Kirkus, yes that does sound like a pain. I've always been a fan of bandwidth, well below 20Hz and well above 20KHz to maintain proper phase reproduction in the audio passband. Both areas can be hard for transformers (which is why I prefer to direc... | |
| Is no preamp the best preamp of all? Daverz, those least significant bits contain detail.Now to your issue about the 30 db. Think about in terms of a magnifying glass. Without the glass you can see a small object and depending on your eyes, all the detail is there. When you use the m... | |
| Modern Linestages Martykl, thanks for the question. I'm not exactly sure how to answer- it might help to tell the story of the MA-3.This is our flagship amplifier. I had the idea of 'something' for a long time but it was pretty nebulous. But along came a customer t... | |
| Tube Phono Stage vs Solid State What do you think? I've heard both sound very good. The biggest difference I hear is that tube units might have more hiss, while transistor units tend to play more surface noise. This has nothing to do with the bandwidth of either BTW. Beyond that a transistor unit ... | |
| Is no preamp the best preamp of all? Daverz, it does not work that way. If you turn the volume down, and assuming that 0db is your 'floor', the quietest portions will still be at or above that floor. This is true of any volume control. | |
| Modern Linestages Charles1dad, regarding your examples- I don't know about all of them but I know about some and those are good examples. | |
| XLR to RCA Adapters Pretty good for a bit of iron, eh?It is indeed! Did you get a chance to check the bandwidth at 10Hz and 5 Hz also? | |
| Is no preamp the best preamp of all? Daverz, on an analog control you will not hear much in the way of a loss of resolution. You may hear some colorations depending on the control and its position, but not a loss of resolution. | |
| Modern Linestages Naturally all products are marketed with consideration to cost.What I was referring to was that there are no strict norms as to mark-up.All products will sell for whatever the market will bear.This statement is just not supported by the facts of t... | |
| XLR to RCA Adapters I do think that it's highly inaccurate to characterize line output transformers, as a group, as requiring a substantial or specific load on the secondary to acheive proper transient response.All of the line output transformers I have ever seen nee... | |
| Is no preamp the best preamp of all? Daverz, usually the problem with digital volume controls occurs when you drop the volume below about 75-85% of full volume, heard as a loss of resolution.To get around this problem many CD players actually have analog controls (which quite often i... | |
| Modern Linestages Grannyring, years ago we had to face the issue of 'what is reference?' To that end we came to the conclusion that no media could be trusted as it all has flaws as you mention.So we used direct microphone feeds. What we found with microphones runni... | |
| Modern Linestages Yes, if I take Grannyring's line of reasoning, he is talking about using synergistic effects to make a system work.Its my opinion that its a Bad Idea to use synergies, for example using a dark preamp to go with a bright source. What you wind up wi... |
